he Merchant Services Web-Services Platform enables partner Merchants to integrate with the Paga platform to enable Paga to process automated real-time payment transactions with the Merchant's systems using secure SOAP Web Services. This specification describes the web-services interfaces that the Merchant must implement for automated integration using Web-Services

The services that are described in this specification are:

Get Supported Integration Services -This service allows Paga to verify which of the integration services listed here the merchant implementation supports in order to configure subsequent interaction with the merchant platform.. This service is mandatory.
Payment Execution -This service provides the mechanism for Paga to submit a payment notification to the merchant systems and receive confirmation of its approval. This service is mandatory.
Customer Validation - This service allows Paga to verify the existence of a customer in good standing with the merchant using several customer properties. This service is optional.
Query Payments- This service provides the mechanism for Paga to request historical payment(s) records from the biller. This service is optional.
Get Merchant Services - This service provides the mechanism for Paga to request a list of named merchant services and associated service properties provide by the merchant. This service is optional.

1. Get Supported Integration Services

This service is mandatory.

To secure the communications between the Paga platform and the merchant systems, there are several communications layer and web-service security requirements and options.
SSL
All communications between the Paga platform and the merchant must be performed over a secure sockets layer (SSL) HTTP communication channel. This means that the merchant must provide an encrypted SSL HHTP address (HTTPS URL).
Username/Password Digest Token
All merchant web-services integrated with the Paga Merchant Services Web-Services must implement the standard Web-Service Security Web Services Security: SOAP Message Security 1.0 Standard 200401, March 2004 which provides a specification for SOAP web-service header username/token authentication credentials.
Within this specification, the service will employ the Password Digest authentication MS-WSP password will be provided along with the username to authenticate the merchant. The merchant's username and MS-WSP password credentials will be provided to the Merchant a part of their Merchant Services registration process.
Certificate Authentication
This authentication method is optional
In order to verify that web-service requests are originating from Paga to the Merchant platform, the Merchant can choose to perform public certificate validation. If this is required by the Merchant, during the registration process, Paga will share a public certificate key with the merchant which can be used to validate that the request originated from the Paga platform.
