Your First Application
If you are adding Sign2Pay to a native application, all you’ll need here is an application name and description.
For web integrations, you’ll be asked to provide a redirect_uri as well. The redirect_uri does most of the heavy lifting of your integration. This is where you will handle both success and error responses returned when asking your users permission to process your request.
This means a publicly available resource hosted on your site that will handle everything from updating your purchase status to redirecting to your complete or error page. Upon a successful authentication, your redirect_uri will receive a request containing the authorization_grant code and state parameters which you then use to obtain the access_token for this user.
