Payment workflow? Callback urls?

Hi, I am developing a simple webapp. I am trying to figure out how to setup a payment workflow, url callbacks.

User pays gets redirected to transaction complete page or cancels and gets sent to a failed page.

I am working with static html, javascript and jquery.

I am looking at both AlgoPay and QR code payments.

Is there anyway of doing this in a simple manner?

I have read the documentation and it mentions nothing about callback urls.

I would recommend you to go through this article below to get a basic understanding of how payment transaction works.

I did that and I can’t find nothing on callback urls

There is no callback / push system available on official SDK/node right now.

You can use 3. Your First Transaction - Algorand Developer Portal
or query the indexer regularly with the transaction ID.
