I would recommend to take the integration hub approach. 

1. Create Connections and Credential Alias

2. Create a Spoke

3. Create a custom REST Action.

4. Create the flow. 

Please mark as helpful if this works.

Here's a short step-by-step guide to build the integration in ServiceNow:

1. Create a REST Message

   Go to System Web Services > Outbound > REST Message.Define the endpoint, HTTP methods, and authentication for the third-party app.

2. Create Scripted REST API (if needed)

   If the third-party app also needs to call ServiceNow, create an inbound REST API under System Web Services > Scripted REST APIs.

3. Use Business Rule for Triggering

   Create a Business Rule on the Incident table with a condition for specific state changes.In the script, call the REST Message using RESTMessageV2().

4. Parse Response

   Parse the response using response.getBody() and JSON.parse().

5. Update Incident Form

   Populate custom fields on the Incident form with the response data using current.<field_name> = value;.

6. Test the Integration

   Change incident state and verify the integration is triggered, and response fields are populated.
