How do configure your account ?

You must contact your account manager to obtain the necessary information to configure your account on Payline (contract and name of the bank).

Then please send an email to our support team with the information, so that they can proceed with the settings in your Payline merchant account, indicating the Merchant ID and the name of the alias of the partner contract to be created.
You must carry out 'pilot' transactions to validate an operation in production.
In the Payline administration center, when creating the payment method, the fields to configure are the Visa and Mastercard contract numbers.

• In Web API or PG Checkout integration: the merchant will use service ID (SID) and Payline Certificate Signing Request (CSR) (recommended).

• In Direct API or Merchant checkout integration: the merchant must retrieve his service ID (SID) from the Partner Portal and communicate the Certificate Signing Request (CSR) via this same channel. The merchant communicates the test / production IP addresses via the Partner Portal so that Samsung Pay can declare them in the system.

To set up Samsung Pay on Payline, you need to create a Samsung Pay account in SellerCentral and retrieve the Merchant ID, NWS Authorization Token, and Customer ID information needed to set up your Payline contract.
To create a Samsung Pay account please refer to the Samsung Pay documentation  and follow the detailed procedure (DirectPayment API).
