Single merchant payments

Note! If you are a Platform (ak.a. BaaS Partner) please use documentation here.

To create and execute single merchant payments that require redirection, you will need to call our Initiate Payment API. The purpose of this API is to receive commercial transactions to Your account. Before calling this API we strongly recommend selecting payment method (PIS – for payment initiation service, CARD – for card-related payments), provider (applicable only for PIS payment method) and language (all these parameters are optional) – to save clicks and steps for your customer.

For testing only. When testing requests in stage environment, please note that not all providers support frontend. We recommend selecting these details while testing:

1. For FI country and PIS method – Test Bank, provider ID 03a4effd-d047-4c3e-ab95-1b4fb198b64f
2. For LT country and PIS method – Siauliu bankas, provider ID a7640cb7-4dec-4a44-a9ad-b918c803254e
3. For CARD payment method, use card No 4242424242424242 for success result and No 4539467987109256 for failed result.

If request was successful, you will receive response with http code 201 and paymentId together with redirectUrl in response body. You have to redirect your customer to redirectUrl to authorize a payment within their provider (bank or card issuer). Save paymentId for further status check.

"payment": {
    "paymentId": "07400128-60a9-47cc-8c99-924cb079a32b",
    "redirectUrl": ""

You can see full sequence diagram below:

After authorization within their bank or issuer, Consumer will be redirected back to widget and will be presented with payment status information. All commercial transactions require SCA for payments or 3DS authorization for card-related payments. Exemptions might be applied by Consumer’s bank or Issuer.

Tip! Delivery of a payment might be different (not all providers support SEPA INST), please check providers and schemes they support here.
