Method to Validate REST API Identity

[Anonymous]

Hi, I'm trying to utilize the REST API, and am attempting to validate the credentials the users would be providing. So far I can validate everything except the REST API Identity.

Besides checking if the link follow a valid URL format, is there a way to validate the identity?

Thanks in advance!

I'm not really sure what you're asking here.  What exactly are you requesting from users, and what component of it are you trying to validate?
