Getting "invalid_grant" when validating the authorization code
Hi, everyone,I'm trying to implement Sign in with Apple and it's been going fine until I tried to valiate the authorization code using the Web Service Endpoint – https://appleid.apple.com/auth/token.The error I'm getting back from the request is invalid_grant.I'm sending the following in the POST request to that URL:code=the_auth_code_given_to_the_app_when_signing_in client_secret=the_jwt_i_generated client_id=com.my.app grant_type=authorization_codeIf I decode the client_secret jwt that I created, it looks like this, which is what the documentation says it should look like.{ "alg": "ES256", "kid": "ABC123DEFG" } { "iss": "DEF123GHIJ", "iat": 1437179036, "exp": 1493298100, "aud": "https://appleid.apple.com", "sub": "com.my.app" }Any ideas? Thanks in advance.
