Mazo Capital Solutions' custom endpoint eliminates all the hassle of creating an application that satisfies all of Salesforce's requirements. We've already done the work, so you can submit Applications here instead.
This makes it unnecessary to use a Salesforce login, or track details like token expiry and the "refresh_token" to renew your session.
Our system takes care of all the authentication stuff, so you can just send us the applicant information and not have to worry about it.
