We could use the access token to access your Azure function API directly if your azure function authentication level is anonymous or function key is also required. The detailed steps are as below.

1. Configure Azure AD for Azure Function. Please refer to https://docs.microsoft.com/en-us/azure/azure-functions/functions-how-to-use-azure-function-app-settings#auth.
2. Get Access token

I get an access token from AAD using clientID and clientSecret using the following code:

METHOD: POST

Url : https://login.microsoftonline.com/your directory ID/oauth2/token 

HEADERS:  Content-Type : application/x-www-form-urlencoded

BODY: grant_type+=client_credentials&resource+=”your Function url”&client_id+++++=”the application that your register  id”&client_secret+=”the key you create”

Please note that according to the Azure Resources portal (https://resources.azure.com/), the default allowedAudiences is

https://{functionAppName}.azurewebsites.net/.auth/login/aad/callback

So I added the https://{functionAppName}.azurewebsites.net/ as allowed audiences.

Then I can use the access token directly. I tested it with Postman:

Please note that if your azure function authentication level is not anonymous, you need to add the function key
