I am trying to implement “Paypal Onboard for Sellers”.
User clicks “Connect Paypal”, then he is directed to “Log In with Paypal”, and finally he comes back to my return_url.
The problem is that at the end of the day, I don’t understand how to retrieve authCode and sharedId from this process.
Paypal literally says
When your seller completes the sign-up flow, PayPal returns an authCode and sharedId to your seller’s browser.
Build onboarding into your software
What is “returns to browser” ? Nobody knows…
