Creating a RESTful service through PRPC in Pega 7.1.8

I would like to create a consumable REST service which is exposed to an external application. Is it possible in Pega 7.1.8 ?

Integration > Service accelerator only allows the following service types -

  • SOAP, .Net, HTTP, EJB, Java, JSR94, JMS, MQ, File

If you need to create a REST Service, you will have to do it manually by creating the following rules:

  • Service package
  • REST service rule
  • Service activity
  • Response stream

Like Sambildikar and RashmiR8 above, I am seeking information on the recommended way to build a RESTful service in PRPC. There is no wizard to do this.

Specifically:

1. How do I generate the Parse JSON and Stream JSON rules that are needed?

2. How do I generate the WADL file that my customer will need to configure his REST connector in SAP?

A good "How-To" guide for REST services in PRPC would be highly appreciated! There seems to be very little information I can find on PDN, and what I can find is very bald, with little detail on how-to.

Thanks in advance.

Hi 

For REST Service there wont be any Parse and Stream JSON required. The response is sent as JSON from the Service Page on which service is run.

Also there is n o WSDL or WADL for JSON and only the sample JSON response is given as refecrnce for the third party developing REST Connector.

If you are using a POST method in Service REST. The request and response mapping looks like below.

Request:

MapTo - JSON

MapToKey - Page Context on which Service is getting request (this will be mapped to Clipboard page on the Servir Page from there you can use this request values for processing).

Example - 

MapToKey - .InputData (example)

this indicates  the request will be available on clipboard in MyServicepPage.InputData. Here the thing to note is all the properties required ineed to be created manually in class of InputData Page.

Response:

In similar lines to request here we have 

MapFrom - JSON

MapFromkey- .OutputData (example)

this indicates  the reponse should  be available on clipboard in MyServicepPage.OutputData . Here the thing to note is all the properties required need to be created manually in class of OutputData Page.

Hi,

The following records need to be configured for a REST service

1. REST Service – Rule that holds service activity, resource path parameter, query string parameters and request/response mapping for each method type.
2. Service Activity – The activity that holds the implementation logic of service method.
3. XML Stream for the response – Source to map the response. The XML stream rule assembles the response data for the message.
4. Service Package – Service Package data instance defines a package name, define access for listeners, and support deployment of services.
