Steps to Integrate Pega with an External REST API

1. Understand the API Requirements:

   • Obtain the API endpoint URL.
   • Understand the request/response format (e.g., JSON or XML).
   • Identify the necessary authentication method (e.g., Basic Auth, OAuth, API keys).
   • Review the API documentation for required parameters and headers.

2. Create a Connector:

   • Use Pega’s Connect-REST rule to create a connector to the external REST API.

3. Configure Authentication:

   • Set up the necessary authentication profile in Pega.

4. Create Data Page:

   • Use a data page to load the data retrieved from the REST API.

5. Map Data:

   • Map the request and response data to and from Pega properties.

6. Test the Integration:

   • Test the connector and data page to ensure the integration works as expected.

Detailed Steps

1. Understand the API Requirements:

   • Obtain the API endpoint, request method (GET, POST, etc.), headers, parameters, and authentication details from the API documentation.

2. Create a Connector:

   • Go to Records > Integration-Connectors > Connect-REST.
   • Click Create to create a new Connect-REST rule.
   • Fill in the details:
     • Endpoint URL: The URL of the REST API.
     • Resource Path: The specific resource path, if needed.
     • HTTP Method: The method used (e.g., GET, POST).

3. Configure Authentication:

   • Go to Records > Security > Authentication Profile.
   • Click Create to create a new authentication profile.
   • Configure the authentication type (Basic, OAuth, etc.) and credentials.

4. Create Data Page:

   • Go to Records > Data Model > Data Page.

   • Click Create to create a new data page.

   • Configure the data page:

     • Mode: Choose "Read-Only".
     • Object Type: The type of data the page will hold (e.g., Customer).
     • Scope: Choose the appropriate scope (Thread, Requestor, Node).

   • In the Data Sources section, choose Connector and select the Connect-REST rule you created.

5. Map Data:

   • In the Connect-REST rule, go to the Request and Response tabs.
   • Map the Pega properties to the API request parameters and response fields.

6. Test the Integration:

   • Test the Connect-REST rule by running it directly and checking the response.
   • Test the data page to ensure it loads data correctly.
