Test Environment

Base URL: https://api-test.sweuze.com/v1

The test environment connects to provider sandboxes - no actual charges occur.

MBWay (mbway-eupago): use any Portuguese-format test phone number (e.g. +351912345678); simulate the approval in the Eupago sandbox app.
Multibanco (multibanco-eupago): returns test entity/reference pairs. Simulate payment via the Eupago sandbox.
Neteller (neteller-paysafe): use Paysafe sandbox wallet credentials.
Paysafecard (paysafecard-trustpayments): use TrustPayments sandbox test vouchers.
Card (card-rillpay): use Rillpay sandbox test cards at the hosted checkout (covers 3DS, declines, soft-declines). Remember to include customerType, kycStatus on paymentMethod, and email, phone, firstName, lastName, dateOfBirth on customer.
Open Banking (openbanking-rillpay): use Rillpay sandbox banks at the hosted checkout. Include customerType, kycStatus on paymentMethod, and email, firstName, lastName, dateOfBirth, nationality on customer (no phone required).

Payment intents can be created for every method enabled on your merchant account (check GET /payment-methods?currency=EUR)
Customer redirects work correctly (Rillpay, Neteller, Paysafecard)
Requisites are displayed correctly (MBWay, Multibanco)
Return URLs handle all statuses
Webhooks are received and signature-validated
Orders are fulfilled only on payment_intent.succeeded / payment.succeeded - never on return URLs
Error scenarios handled gracefully (422, 502)
Idempotency prevents duplicates (same reference reuses the existing intent)
Monitoring configured
