JSON Web Token (JWT) UserIdentityTokens can be passed to the Server using the IssuedIdentityToken. The body of the token is a string that contains the JWT as defined in RFC 7159.
Servers that support JWT authentication shall provide a UserTokenPolicy which specifies the Authorization Service which provides the token and the parameters needed to access that service. The parameters are specified by a JSON object specified as the issuerEndpointUrl. The contents of this JSON object are described in Table 39. The general UserTokenPolicy settings for JWT are defined in Table 38.
