Hi Robert,
You can find documentation and samples for auth0-php@7.9
on the Auth0 website. The Auth0 PHP SDK provides a Token
class that can decode, validate, and verify JSON Web Tokens (JWTs) for your application Reference
This SDK supports both HS256
and RS256
tokens. To decode HS256
tokens, you will need to configure a client secret. On the other hand, RS256
tokens require an authorized issuer. The SDK also includes a utility for token processing, which offers customizable options for verification and validation.
Regarding your question about the token, it is a plain JWT. You can check it with the client secret from your app’s page Reference
