How to validate scope parameter in Web APIs

Certified Senior Developer

Hi all, 

We need to validate the scope parameter in Web APIs. I've seen in the documentation that with the Appian OAuth 2.0 client the scope parameter must either be blank or omitted entirely:

https://docs.appian.com/suite/help/24.1/Web_API_Authentication.html#using-the-oauth-2.0-client-credentials-grant

Can we use a third-party OAuth 2.0 client to validate scope parameter? With this authentication method, would the scope be validated internally or would we have to do it at the web API level?

Thanks in advance.
