Hi!

I’m using checkout API (POST /v2/online-checkout/payment-links). According to the documentation, Square should add orderId, transactionId, and referenceId to the URL specified in redirect\_url parameter. However, this is not happening (at least in sandbox environment). Square redirects to the URL “as specified”, and all of the transaction information is missing.

Is this behavior expected? I need to pass transaction information back to my website. Thanks!

Sincerely,  
Ilya

Yes, this is the expected behavior in sandbox because payment links aren’t fully supported in sandbox. In production the `orderId` will be appended to the end of the `redirect URL`. 🙂
