I’m following the PHP example listed here: connect-api-examples/connect-examples/v2/php_checkout at master · square/connect-api-examples · GitHub
Where would the redirect_url be configured if I were to implement it in this example?
Per the documentation:
You can also configure a URL for customers to be redirected to, once they complete their purchase, to verify that the payment went through successfully.
I saw others referencing something like this:
However, it does not work and apache logs show $checkout as undefined.
