def (access_token)
  headers = {
    Authorization: "Bearer #{access_token}"
  }

  IntuitOAuth::Transport.request('GET', @client., headers=headers)
end

#validate_id_token(id_token) ⇒ Boolean

If the token can be correctly validated, returns True. Otherwise, return false

The validation rules are:
1.You have to provide the client_id value, which must match the
token's aud field
2.The payload issuer is from Intuit
3.The expire time is not expired.
4.The signature is correct

If something fails, raises an error

Parameters:

  • id_token (String)

    The string form of the token

Returns:

  • (Boolean)
