Buy now pay later

Antom is planning to add some payment methods with the Buy Now Pay Later (BNPL) feature. BNPL is a type of installment loan, which gives a buyer a certain credit line that is long-term effective and recyclable. The buyer can use this credit line for transactions. However, payment methods still need to apply real-time risk control to BNPL transactions to reduce risks on the buyer side and the payment method side, which requires merchants to provide specific information in the API request to Antom. The required information is categorized into basic ones and extended ones, and they have a heavy impact on the success of payments.

Requirements for merchants

Certain parameters are required for the pay API requests. See the following sections for details.

Basic info parameters
