Error Responses

Following are errors returned by the Hellō server when making an authorization request, or when calling the introspection API.

Authorization Request Errors

If there is an issue with fulfilling the request, the response (Step 4) will have an error query parameter set to one of the following string:

Error	Description
`invalid_request`	The request is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, or is otherwise malformed.
`access_denied`	The user denied or cancelled the request.
`invalid_scope`	The requested scope is invalid, unknown, or malformed.
`server_error`	The Hellō server encountered an unexpected condition that prevented it from fulfilling the request. (This error code is equivalent to a 500 Internal Server Error HTTP status code.)
`temporarily_unavailable`	The Hellō server is currently unable to handle the request due to a temporary overloading or maintenance of the server. (This error code is equivalent to a 503 Service Unavailable HTTP status code.)

Example

*NOTE: If the request contains an invalid client_id or request_uri, a response will not be sent and the user will be presented with an error message per RFC 6749 4.1.2.1 (opens in a new tab)

Introspection Errors

Following are the responses from the Token Introspection API https://wallet.hello.coop/oauth/introspect

If the token is invalid in anyway, the API will return active set to false

{
    "active":false
}

If any of the parameters are missing you will receive an error

Error	Description
`token_required`	There was no `token` parameter.
`client_id_required`	There was no `client_id` parameter.
`nonce_required`	There was a nonce in the ID Token, and there was no `nonce` parameter.

Example

{
    "error":"nonce_required"
}
