Where does seller authorize application?

[Jimmy89]

But I am still missing the clarity on the last piece of integration.. On the seller side, when my square up showed up and customer ready to give a scope of what I need as part of app integration.. Where he authorize.. My assumption is that all the existing apps in the marketplace are redirecting to their websites.. The redirect URL I had set as part of the application when does that get's triggered?? Does I have to build a page on my website to get authorization from the customer?

A high level overview can be seen here. A word from our API Team:

To be more specific, the redirect URL is "triggered" if the seller approves their application. As soon as they approve, they will be redirected to the URL they provided in the request, with additional parameters (such as a code) so they can generate an OAuth access token for the seller. They do not necessarily need a front-facing web page, but they would at least need a server-side endpoint that they redirect to so they can get the code.

Hope this helps 🙂
