In all cases above the integration can be done using Everifin UI (recommended) or Everifin API. The following table shows which combinations are allowed for which use case:
One-time payment | Payments from saved bank accounts | Payments from Everifin accounts | |
|---|---|---|---|
User registration/login | not applicable | not applicable, the merchant is logged-in via API | Everifin UI (Multibanking or Wallet) * |
Connecting bank accounts | not applicable | Everifin UI (Paygate Redirect flow) | Everifin UI (Multibanking or Wallet) * |
Payment initiation | Everifin UI (Paygate Redirect flow) |
Everifin |
Everifin UI (Paygate Redirect flow) |
/ Everifin API (/wiki/spaces/~5dd3fb319def2a0ee974c384/pages/2469232674)
* - this step is done outside Paygate as a pre-requisite

Everifin UI is the simplest method of integration and for maintenance. It takes the user to a trusted and licensed payment services provider Everifin (e.g. using a redirect or a modal window). The user can safely authorize the payment and return back without sharing any sensitive data with the original client application (an accounting system, an ERP, an e-shop, etc). Unless there are API breaking changes to the payment status call or link creation call, no additional development is required to leverage the latest Everifin Paygate updates.
Everifin API
Everifin API is a more complex integration method which requires the client application to take care about the specifics of the payment authorization process itself. E.g. it must store the list of connected bank accounts, monitor the status of each connection, handle different types of payment authorization processes supported by the banks (redirect to a bank, embedded in the application and decoupled) each with multiple types of authorization factors (push notification, SMS, one-time code, QR code scan, etc).
