Azure OpenAI in Microsoft Foundry Models REST API reference

Learn how to use Azure OpenAI’s REST API. In this article, you learn about authorization options, how to structure a request and receive a response.

This article provides details on the inference REST API endpoints for Azure OpenAI.

API specs

Managing and interacting with Azure OpenAI models and resources is divided across three primary API surfaces:

• Control plane
• Data plane - authoring
• Data plane - inference

Each API surface/specification encapsulates a different set of Azure OpenAI capabilities. Each API has its own unique set of preview and stable/generally available (GA) API releases. Preview releases currently tend to follow a monthly cadence.

There is now a new preview inference API. Learn more in our API lifecycle guide.

API	Latest preview release	Latest GA release	Specifications	Description
Control plane	2025-07-01-preview	2025-06-01	Spec files	The control plane API is used for operations like creating resources, model deployment, and other higher level resource management tasks. The control plane also governs what is possible to do with capabilities like Azure Resource Manager, Bicep, Terraform, and Azure CLI.
Data plane	v1 preview	v1	Spec files	The data plane API controls inference and authoring operations.

Authentication

Azure OpenAI provides two methods for authentication. You can use either API Keys or Microsoft Entra ID.

• API Key authentication: For this type of authentication, all API requests must include the API Key in the api-key HTTP header. The Quickstart provides guidance for how to make calls with this type of authentication.

• Microsoft Entra ID authentication: You can authenticate an API call using a Microsoft Entra token. Authentication tokens are included in a request as the Authorization header. The token provided must be preceded by Bearer, for example Bearer YOUR_AUTH_TOKEN. You can read our how-to guide on authenticating with Microsoft Entra ID.

REST API versioning

The service APIs are versioned using the api-version query parameter. All versions follow the YYYY-MM-DD date structure. For example:

POST https://YOUR_RESOURCE_NAME.openai.azure.com/openai/deployments/YOUR_DEPLOYMENT_NAME/chat/completions?api-version=2024-06-01

Data plane inference

The rest of the article covers the GA release of the Azure OpenAI data plane inference specification, 2024-10-21.

Completions

POST https://{endpoint}/openai/deployments/{deployment-id}/completions?api-version=2024-10-21

Creates a completion for the provided prompt, parameters, and chosen model.

URI Parameters

Name	In	Required	Type	Description
endpoint	path	Yes	string url	Supported Azure OpenAI endpoints (protocol and hostname, for example: https://aoairesource.openai.azure.com. Replace “aoairesource” with your Azure OpenAI resource name). https://{your-resource-name}.openai.azure.com
deployment-id	path	Yes	string	Deployment ID of the model which was deployed.
api-version	query	Yes	string	API version

Request Header

Name	Required	Type	Description
api-key	True	string	Provide Azure OpenAI API key here

Request Body

Content-Type: application/json

Name	Type	Description	Required	Default
prompt	string or array	The prompt(s) to generate completions for, encoded as a string, array of strings, array of tokens, or array of token arrays. Note that <|endoftext|> is the document separator that the model sees during training, so if a prompt isn’t specified the model will generate as if from the beginning of a new document.	Yes
best_of	integer	Generates best_of completions server-side and returns the “best” (the one with the highest log probability per token). Results can’t be streamed. When used with n, best_of controls the number of candidate completions and n specifies how many to return – best_of must be greater than n. Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for max_tokens and stop.	No	1
echo	boolean	Echo back the prompt in addition to the completion	No	False
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model’s likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by their token ID in the GPT tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token. As an example, you can pass {"50256": -100} to prevent the <|endoftext|> token from being generated.	No	None
logprobs	integer	Include the log probabilities on the logprobs most likely output tokens, as well the chosen tokens. For example, if logprobs is 5, the API will return a list of the five most likely tokens. The API will always return the logprob of the sampled token, so there may be up to logprobs+1 elements in the response. The maximum value for logprobs is 5.	No	None
max_tokens	integer	The maximum number of tokens that can be generated in the completion. The token count of your prompt plus max_tokens can’t exceed the model’s context length.	No	16
n	integer	How many completions to generate for each prompt. Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for max_tokens and stop.	No	1
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.	No	0
seed	integer	If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. Determinism isn’t guaranteed, and you should refer to the system_fingerprint response parameter to monitor changes in the backend.	No
stop	string or array	Up to four sequences where the API will stop generating further tokens. The returned text won’t contain the stop sequence.	No
stream	boolean	Whether to stream back partial progress. If set, tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.	No	False
suffix	string	The suffix that comes after a completion of inserted text. This parameter is only supported for gpt-3.5-turbo-instruct.	No	None
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.	No	1
user	string	A unique identifier representing your end-user, which can help to monitor and detect abuse.	No

URI Parameters

Name	In	Required	Type	Description
endpoint	path	Yes	string url	Supported Azure OpenAI endpoints (protocol and hostname, for example: https://aoairesource.openai.azure.com. Replace “aoairesource” with your Azure OpenAI resource name). https://{your-resource-name}.openai.azure.com
deployment-id	path	Yes	string	Deployment ID of the model which was deployed.
api-version	query	Yes	string	API version

Request Header

Name	Required	Type	Description
api-key	True	string	Provide Azure OpenAI API key here

Request Body

Content-Type: application/json

Name	Type	Description	Required	Default
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.	No	1
stream	boolean	If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.	No	False
stop	string or array	Up to four sequences where the API will stop generating further tokens.	No
max_tokens	integer	The maximum number of tokens that can be generated in the chat completion. The total length of input tokens and generated tokens is limited by the model’s context length.	No
max_completion_tokens	integer	An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens.	No
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.	No	0
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model’s likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.	No	None
user	string	A unique identifier representing your end-user, which can help to monitor and detect abuse.	No
messages	array	A list of messages comprising the conversation so far.	Yes
data_sources	array	The configuration entries for Azure OpenAI chat extensions that use them. This additional specification is only compatible with Azure OpenAI.	No
logprobs	boolean	Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of message.	No	False
top_logprobs	integer	An integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability. logprobs must be set to true if this parameter is used.	No
n	integer	How many chat completion choices to generate for each input message. Note that you’ll be charged based on the number of generated tokens across all of the choices. Keep n as 1 to minimize costs.	No	1
parallel_tool_calls	ParallelToolCalls	Whether to enable parallel function calling during tool use.	No	True
response_format	ResponseFormatText or ResponseFormatJsonObject or ResponseFormatJsonSchema	An object specifying the format that the model must output. Compatible with GPT-4o, GPT-4o mini, GPT-4 Turbo and all GPT-3.5 Turbo models newer than gpt-3.5-turbo-1106. Setting to { "type": "json_schema", "json_schema": {...} } enables Structured Outputs which guarantees the model will match your supplied JSON schema. Setting to { "type": "json_object" } enables JSON mode, which guarantees the message the model generates is valid JSON. Important: when using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly “stuck” request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length.	No
seed	integer	This feature is in Beta. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. Determinism isn’t guaranteed, and you should refer to the system_fingerprint response parameter to monitor changes in the backend.	No
tools	array	A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for. A max of 128 functions are supported.	No
tool_choice	chatCompletionToolChoiceOption	Controls which (if any) tool is called by the model. none means the model won’t call any tool and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools. Specifying a particular tool via {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool. none is the default when no tools are present. auto is the default if tools are present.	No
function_call	string or chatCompletionFunctionCallOption	Deprecated in favor of tool_choice. Controls which (if any) function is called by the model. none means the model won’t call a function and instead generates a message. auto means the model can pick between generating a message or calling a function. Specifying a particular function via {"name": "my_function"} forces the model to call that function. none is the default when no functions are present. auto is the default if functions are present.	No
functions	array	Deprecated in favor of tools. A list of functions the model may generate JSON inputs for.	No

Be watchful for signs of sickness, such as lethargy, loss of appetite, puffin' up, or change in droppings, and make haste to a vet if need be.\n\n8. Provide fresh air 'n avoid toxins: Parrots be sensitive to draft and pollutants. Keep yer quarters well ventilated, but no drafts, arrr!

chatCompletionsRequestCommon

Name	Type	Description	Required	Default
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.	No	1
stream	boolean	If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.	No	False
stop	string or array	Up to four sequences where the API will stop generating further tokens.	No
max_tokens	integer	The maximum number of tokens allowed for the generated answer. By default, the number of tokens the model can return will be (4096 - prompt tokens). This value is now deprecated in favor of max_completion_tokens, and isn’t compatible with o1 series models.	No	4096
max_completion_tokens	integer	An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens.	No
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.	No	0
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model’s likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a json object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.	No
user	string	A unique identifier representing your end-user, which can help Azure OpenAI to monitor and detect abuse.	No

createCompletionRequest

Name	Type	Description	Required	Default
prompt	string or array	The prompt(s) to generate completions for, encoded as a string, array of strings, array of tokens, or array of token arrays. Note that <|endoftext|> is the document separator that the model sees during training, so if a prompt isn’t specified the model will generate as if from the beginning of a new document.	Yes
best_of	integer	Generates best_of completions server-side and returns the “best” (the one with the highest log probability per token). Results can’t be streamed. When used with n, best_of controls the number of candidate completions and n specifies how many to return – best_of must be greater than n. Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for max_tokens and stop.	No	1
echo	boolean	Echo back the prompt in addition to the completion	No	False
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model’s likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by their token ID in the GPT tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token. As an example, you can pass {"50256": -100} to prevent the <|endoftext|> token from being generated.	No	None
logprobs	integer	Include the log probabilities on the logprobs most likely output tokens, as well the chosen tokens. For example, if logprobs is 5, the API will return a list of the five most likely tokens. The API will always return the logprob of the sampled token, so there may be up to logprobs+1 elements in the response. The maximum value for logprobs is 5.	No	None
max_tokens	integer	The maximum number of tokens that can be generated in the completion. The token count of your prompt plus max_tokens can’t exceed the model’s context length.	No	16
n	integer	How many completions to generate for each prompt. Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for max_tokens and stop.	No	1
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.	No	0
seed	integer	If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. Determinism isn’t guaranteed, and you should refer to the system_fingerprint response parameter to monitor changes in the backend.	No
stop	string or array	Up to four sequences where the API will stop generating further tokens. The returned text won’t contain the stop sequence.	No
stream	boolean	Whether to stream back partial progress. If set, tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.	No	False
suffix	string	The suffix that comes after a completion of inserted text. This parameter is only supported for gpt-3.5-turbo-instruct.	No	None
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.	No	1
user	string	A unique identifier representing your end-user, which can help to monitor and detect abuse.	No

createCompletionResponse

Represents a completion response from the API. Note: both the streamed and nonstreamed response objects share the same shape (unlike the chat endpoint).

Name	Type	Description	Required	Default
id	string	A unique identifier for the completion.	Yes
choices	array	The list of completion choices the model generated for the input prompt.	Yes
created	integer	The Unix timestamp (in seconds) of when the completion was created.	Yes
model	string	The model used for completion.	Yes
prompt_filter_results	promptFilterResults	Content filtering results for zero or more prompts in the request. In a streaming request, results for different prompts may arrive at different times or in different orders.	No
system_fingerprint	string	This fingerprint represents the backend configuration that the model runs with. Can be used in conjunction with the seed request parameter to understand when backend changes have been made that might impact determinism.	No
object	enum	The object type, which is always “text_completion” Possible values: text_completion	Yes
usage	completionUsage	Usage statistics for the completion request.	No

createChatCompletionRequest

Name	Type	Description	Required	Default
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.	No	1
stream	boolean	If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.	No	False
stop	string or array	Up to four sequences where the API will stop generating further tokens.	No
max_tokens	integer	The maximum number of tokens that can be generated in the chat completion. The total length of input tokens and generated tokens is limited by the model’s context length.	No
max_completion_tokens	integer	An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens.	No
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.	No	0
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model’s likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.	No	None
user	string	A unique identifier representing your end-user, which can help to monitor and detect abuse.	No
messages	array	A list of messages comprising the conversation so far.	Yes
data_sources	array	The configuration entries for Azure OpenAI chat extensions that use them. This additional specification is only compatible with Azure OpenAI.	No
logprobs	boolean	Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of message.	No	False
top_logprobs	integer	An integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability. logprobs must be set to true if this parameter is used.	No
n	integer	How many chat completion choices to generate for each input message. Note that you’ll be charged based on the number of generated tokens across all of the choices. Keep n as 1 to minimize costs.	No	1
parallel_tool_calls	ParallelToolCalls	Whether to enable parallel function calling during tool use.	No	True
response_format	ResponseFormatText or ResponseFormatJsonObject or ResponseFormatJsonSchema	An object specifying the format that the model must output. Compatible with GPT-4o, GPT-4o mini, GPT-4 Turbo and all GPT-3.5 Turbo models newer than gpt-3.5-turbo-1106. Setting to { "type": "json_schema", "json_schema": {...} } enables Structured Outputs which guarantees the model will match your supplied JSON schema. Setting to { "type": "json_object" } enables JSON mode, which guarantees the message the model generates is valid JSON. Important: when using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly “stuck” request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length.	No
seed	integer	This feature is in Beta. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result. Determinism isn’t guaranteed, and you should refer to the system_fingerprint response parameter to monitor changes in the backend.	No
tools	array	A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for. A max of 128 functions are supported.	No
tool_choice	chatCompletionToolChoiceOption	Controls which (if any) tool is called by the model. none means the model won’t call any tool and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools. Specifying a particular tool via {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool. none is the default when no tools are present. auto is the default if tools are present.	No
function_call	string or chatCompletionFunctionCallOption	Deprecated in favor of tool_choice. Controls which (if any) function is called by the model. none means the model won’t call a function and instead generates a message. auto means the model can pick between generating a message or calling a function.
