Explain Service REST integration in Pega

 REST integration in Pega is a process that allows two different systems to exchange data with each other via a standardized protocol such as REST (Representational State Transfer). This is done by creating an API that the two systems can use to communicate with each other. The API acts as a bridge between the two systems and can move data from one to the other and vice versa. The API is usually accompanied by a couple of web services that need to be invoked in order to complete the integration. These web services may include authentication, authorization, data transfer and other services needed to complete the integration. By leveraging the power of REST, Pega can provide integration to various systems and services, giving users greater flexibility and control over their data.

Service REST integration in Pega is a feature of the Pega platform that enables an organization to access and manage web services to interact with external systems. It is based on Representational State Transfer (REST) architecture and allows developers to configure services to interact with external applications using HTTP protocol. It provides a unified approach to transfer data between applications across different domains. With Pega Service REST integration, developers can define a service with a description of the parameters to be sent or received, define the service operation mappings, identify the data source, and configure security to the service. With this integration in Pega, organizations can benefit in terms of cost savings and customer satisfaction.

Service REST integration in Pega allows systems to exchange data in a structured and easy-to-use format. This integration helps to make communication more efficient, less complicated, and cost-effective. With this integration, applications can send and receive data from other systems with minimal effort. This integration is possible through representational state transfer (REST) web services. In this approach, web services have a set of resources that can be modified using the HTTP protocol. All operations that can be performed against these resources are expressed as HTTP request methods (such as GET, POST, PUT, and DELETE), which are made accessible to the interfaces of the external systems. Through this integration, Pega can easily access service layer functionality from a remote system and use the data within the platform. It is also possible to create a system link by exposing a service in Pega to the external system.
