Welcome to the Getting started page, this page will provide you with the information required to get started with Paga Merchant Services |
1. Overview
This document will guide you in implementing the Paga RESTful Merchant Services API. Which you can use to execute the different Paga services exposed to Merchants. This API works for both JSON and XML determined by the HTTP request Accept header value.
2. PAGA Merchant API
The PAGA Merchant API platform exposes operations that are useful for Merchants to provide PAGA’s services to themselves or third-party clients. The Paga Merchant Services are:
- Get Transaction Details
This service allows the merchant to verify the status and details of an executed transaction using the pre-shared transaction reference number. - Get Transaction Details By Invoice Number
This service allows the merchant to verify the status and details of the executed transaction using the invoice number. - Get Process Details
This service allows the merchant to verify the status and details of an executed process. - Reconciliation Report
This service allows the merchant to get any settlement reconciliation items generated for payments intended for the merchant made through the platform. - Get Foreign Exchange Rate
This service allows a merchant to get foreign exchange rates between two currencies. - Refund Bill Pay
This service method allows a merchant to refund Bill Pay transaction made to Paga by a customer.
3. Paga Authentication Details
As of this time, Paga Merchant authentication details have to be obtained directly from Paga. That will change in the near future.
The steps required to obtain authentication details are outlined below.
- Create a Paga Business account
- Send and email to the Paga Operations Support team.
- You will be contacted by a Paga representative that will provide you with the information you require.
4. Implementations
Get Transaction Details
This service allows the merchant to verify the status and details of an executed process or to determine if a transaction was indeed executed on the system using the pre-shared transaction reference number. The transaction reference number used is unique across the platform, so merchant aggregators checking for transaction status across multiple users should use this method.
