Payment form on the site as an example where to find?

Question

Fintech

Tell me, who knows where you can get such or a similar payment form, plugin, script or application on the site like salsabil.info/donate-vibor.html here .
Thanks to all.

Answer 1

What are you actually looking for on the Internet?
A form that magically allows your site to accept payments?
In fact, only banks have the right to do this.
Connect to payment systems, their documentation contains enough examples of how a payment request is generated.
