Online Checkout Link - can I pass it variables, and can it return to a dynamic link?

[rainkid]

I have a Square account and created my first Online Checkout Link for a subscription product. On my webpage, I can link to this Online Checkout link, however, is it possible for me to interface with the online checkout link?

For example, on my webpage, the user has to be signed in for the payment link to appear. Can I pass the username to the online checkout link? Once the user has paid and checked out, can the return page include a variable such as http://www.mydomain.com/squaresuccessfulpayment.php?username=$Username ?

Or do I need to use the full access API for this sort of customization? I'm trying to do this as quickly and simply as possible since I only have one product to sell and don't want to invest a lot of time into programming a full cart with Square's API.

Thank you.

Hello @rainkid 

And WELCOME to our Seller Community, it's always exciting to see new faces. 

The checkout page and landing page after successful checkout cannot be edited for security reasons. 

Now, depending on the type of checkout link you create, you can or cannot add a link to redirect to after a successful checkout. 

The Collect a payment and Accept a donation checkout link have advanced settings that allow you to redirect to a website after checkout. If you are selling an item or event/class you won't be able to add a redirect link, unfortunately. 

There is an active feature request for this feature, I would suggest commenting on that thread to add your voice to the request. 

Using our API, you would be able to have Square redirect your customers to a page of your choosing after a successful checkout, but the checkout page itself is not customizable. 

I hope this helps! 

Thank you ✨

Thank you for the information.

Does an order that goes through the Online Checkout link trigger the payment/order webhooks?

What is the purpose of the Custom Fields in the Online Checkout page? That is, can I pass a variable to it, or can I extract it's contents post-order?

Hello MayaP,

I'm referring to the Square developer webhook subscriptions:

https://developer.squareup.com/docs/webhooks/v2webhook-events-tech-ref

Do webhooks only work with orders made through API event calls, or are they triggered regardless of how an event is triggered?

I guess my situation is - I want to use Square's Online Checkout link for its simplicity, but I want to be able to track my user through the checkout process. Is this possible, or must I use the API for user and order tracking? Specifically, I sell a subscription service. User has to be logged in to my website. They then click the Online Checkout link and go through the payment process. Square can then link user back to a static page on my website. However, how can my site know that this user has completed the checkout process? I can absolutely do this using the API and also using webhooks, but I'm curious if this can be done using just the Online Checkout link functionality.
