Token Introspection (Refresh Token)

POST {{authPath}}/{{envID}}/as/introspect

The POST /{{envID}}/as/introspect endpoint returns information about the refresh token.

You need to authenticate using the client credentials for the client that was issued the token. Note that the application’s tokenEndpointAuthMethod property value determines how you authenticate. The tokenEndpointAuthMethod property supports these options: CLIENT_SECRET_BASIC, CLIENT_SECRET_JWT, PRIVATE_KEY_JWT, CLIENT_SECRET_POST, and NONE.

In the sample request shown here, the application’s tokenEndpointAuthMethod value is CLIENT_SECRET_BASIC, which requires the Authorization: Basic HTTP header and a Base64-encoded representation of "username:password" in the request, in which the username is the client_id and the password is the client_secret.

If the application’s tokenEndpointAuthMethod value is CLIENT_SECRET_JWT, the token endpoint uses a JWT signed by the application’s client secret to authenticate the request. For information about creating the JWT and the claims in the JWT, refer to Create a client secret JWT. Token requests that use this auth method require the client_assertion and client_assertion_type OAuth properties to specify the JWT:

curl --location --request POST '{{authPath}}/{{envID}}/as/introspect' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_assertion={{clientSecretJWT}}' \
--data-urlencode 'client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer'
--data-urlencode 'token={{refreshToken}}'

If the application’s tokenEndpointAuthMethod value is PRIVATE_KEY_JWT, the token endpoint uses a JWT signed by an external private key file to authenticate the request. For information about creating the JWT and the claims in the JWT, refer to Create a private key JWT. Token requests that use this auth method require the client_assertion and client_assertion_type OAuth properties to specify the JWT:

curl --location --request POST '{{authPath}}/{{envID}}/as/introspect' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_assertion={{privateKeyJWT}}' \
--data-urlencode 'client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer'
--data-urlencode 'token={{refreshToken}}'

If the application’s tokenEndpointAuthMethod value is CLIENT_SECRET_POST, the request does not need an Authorization header, and the client_id and client_secret property values are submitted in the request body:

curl --location --request POST '{{authPath}}/{{envID}}/as/introspect' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id={{appID}}' \
--data-urlencode 'client_secret={{appSecret}}'\
--data-urlencode 'token={{refreshToken}}'

If the application’s tokenEndpointAuthMethod value is NONE, the request requires the client_id property value in the request body and does not require an Authorization header:

curl --location --request POST '{{authPath}}/{{envID}}/as/introspect' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id={{appID}}' \
--data-urlencode 'token={{refreshToken}}'

The exp claim in a refresh token is expressed in epoch seconds (time in seconds since January 01, 1970), and resolves to a specific date and time. The value is calculated based on the lesser of current time + refreshTokenDuration and original token minting time + refreshTokenRollingDuration. The "original token minting time" is the time the user last authenticated using an authorization_code grant type on the /token endpoint and received the initial refresh token.

For more information about the refreshTokenDuration and refreshTokenRollingDuration OpenID Connect application properties, refer to the Applications OIDC settings data model.

Prerequisites

  • Use the Token endpoint to create an refreshToken.
