Define a Trigger with Webhook Transformation

Learn how to define a trigger that transforms a webhook payload into a simplified format, which is displayed in the Oracle Integration mapper.

Prerequisites:

Define a schema representing the trigger object, to be presented to the Oracle Integrationorchestration or mapper.
Define a schema representing the actual webhook received by Oracle Integration.
Ensure a flow for transforming data exists in the adapter definition document. For information on how to define a flow, see Invoke a POST API.

In VS Code, click Explorer on the sidebar.
The directory structure of your workspace folder is displayed.
Within the definitions directory listing, click the adapter definition document that you want to work on.
The document is displayed in the VS Code editor.
In the triggers section of the document, define a pass-through trigger. See Define a Pass-Through Trigger.
Add a webhook with the body referencing its schema.

In execute object, refer to the data-transformation flow.

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

"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"
          }
        }
     }
    }
}
