In the redirect flow the user is redirected to Everifin Paygate page where user can process the payment (select the bank and continue to bank SCA). In this flow:
the merchant’s system initializes the order,
redirects to URL received in the response
and then, once the payer is redirected back to merchant system, checks the payment or order status
This makes the redirect flow much simpler for implementation comparing to the embedded (full API) flow.
Order initialization
In order initialization you send the information about the order and its first payment to Everifin. Everifin responds with an order ID, processable payment ID and redirect link pointing to Everifin Paygate page.
