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

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, see Applications settings data model.
