V1.0 for Microsoft Entra-only applications. Web APIs have one of the following versions selected as a default during registration: These versions determine the claims that are in the token and make sure that a web API can control the contents of the token. There are two versions of access tokens available in the Microsoft identity platform: v1.0 and v2.0. It doesn't apply to tokens issued for Microsoft-owned APIs, nor can those tokens be used to validate how the Microsoft identity platform issues tokens for a registered API. See the following sections to learn how an API can validate and use the claims inside an access token.Īll documentation on this page, except where noted, applies only to tokens issued for registered APIs. This data allows the application to do intelligent caching of access tokens without having to parse the access token itself. This information includes the expiry time of the access token and the scopes for which it's valid. When the client requests an access token, the Microsoft identity platform also returns some metadata about the access token for the consumption of the application. Tokens that a Microsoft API receives might not always be a JWT that can be decoded.Ĭlients should use the token response data that's returned with the access token for details on what's inside it. For validation and debugging purposes only, developers can decode JWTs using a site like jwt.ms. The contents of the token are intended only for the API, which means that access tokens must be treated as opaque strings. These proprietary formats that can't be validated might be encrypted tokens, JWTs, or special JWT-like. Microsoft-developed APIs like Microsoft Graph or APIs in Azure have other proprietary token formats. The format of the access token can depend on the configuration of the API that accepts it.Ĭustom APIs registered by developers on the Microsoft identity platform can choose from two different formats of JSON Web Tokens (JWTs) called v1.0 and v2.0. Some identity providers (IDPs) use GUIDs and others use encrypted blobs. Per the OAuth specification, access tokens are opaque strings without a set format. Web APIs use access tokens to perform authentication and authorization. "aud": " tokens enable clients to securely call protected web APIs.
