Define a Trigger with Webhook Transformation

The Rapid Adapter Builder developer can use triggers to host APIs that can receive webhook events.

This procedure gives an overview of how you can transform a webhook payload into a simplified format that is exposed in the Oracle Integration mapper.

Ensure to:

• Define a schema representing trigger object to be presented to orchestration/Mapper
• Define a schema representing actual webhook received by Oracle Integration.
• Flow to transform exists in the adapter definition document. For more information on how to define a flow, see Create a Flow for invoking a POST API.

1. Open the adapter definition document in Visual Studio Code Editor.
2. In the triggers code section, define a pass-through trigger. For more information on how to define a pass-through trigger, refer .
3. Add webhook with body referencing its schema.
4. Refer to flow in execute.

   The following sample code shows how to refer to a flow in the execute:

   "triggers":{
      "pageChangeEvent": {
         "displayName": "Wiki Page Updated Event",
         "description": "This trigger detects when a Wiki Page Updated Event has been raised.",
         "type": "webhook",
         "httpMethod": "POST",
         "request": {
           "schemaType": "application/schema+json",
           "schema": {
             "$ref": "#/schemas/eventSchema"
           }
         },
         "execute": "flow:handleNotificationRequestFlow",
         "webhook": {
             "body": {
             "schemaType": "application/schema+json",
             "schema": {
               "$ref": "#/schemas/webhookSchema"
             }
           }
        }
       }
   }
