For example, if I created a static payment through Square website https://square.link/u/XxXxXxXxXxXxXx, can I add extra parameter like this https://square.link/u/XxXxXxXxXxXxXx?session_id=ABC so that when I receive webhook POST the input data would have session_id=ABC in there?
Stripe supports this, which I think is very convenient for people who find it inconvenient to generate dynamic payment links for each checkout session. As I’m new to Square, I want to ask if there is a similar feature. Thanks!
You can add this to a
redirect_url when you create a link with the Checkout API.
Not sure how that works, but the point is I want to avoid creating a new payment link each time using the API. If I specify redirect_url at the link creation time, I can’t change it without creating a new link, right?
Each link you create with the API is a one time use link. You’ll have to crate a new link for every customer. Unless you use the checkout link created in the Seller Dashboard. If you use that link there there’s no way to pass extra parameters.
Good to know, thanks! I will try to propose this as a feature request, as I think it is important.
