PayByLink
Pay By Link is a well-known payment method in Poland that allows customers paying their online shopping using their Bank accounts. SIBS Payment Gateway provides the API to integrate with Pay By Link services through the Web Redirect pattern.
The API provides the means to present your customer with the payment wall with all addressable entities. Once the customer chooses the entity to use, just call the API that will provide you with the appropriate redirect URL.
How it works
Before you start, you should create the order request with PayByLink as payment method.
After that, you should perform the following steps:
Step 1: Get the list of all Pay By Link entities and present them to the customer
Step 2: Call the API to get a valid Payment Link for the chosen entity
