What You’ll Need

• Enable Post-call summary in Amazon Connect (via Contact Lens).
• Use a Lambda function to push the summary to Salesforce.
• Create a custom Apex REST endpoint in Salesforce to accept the data.
• Store the summary on the custom field on VoiceCall object.

Step 1: Enable Post-Call Summaries in Amazon Connect

Step 2: Trigger a Lambda When the Call Ends

Use Amazon EventBridge to create a rule that will trigger the lambda once the call is Disconnected.

Step 3: Lambda Fetches the Summary and Sends to Salesforce

Here’s what your Lambda needs to do:

1. Grab the contact ID and instance ID from the event.
2. Use AWS SDK to get the summary from Amazon Connect Contact Lens.
3. Send it to Salesforce via an HTTP POST request.

A simplified version of the lambda code:

NOTE : Instead of hardcoding the domain value/ bearer token within the Lambda function, consider storing it as an environment variable.

Step 4: Salesforce Receives the Summary

In Salesforce, create an Apex class that acts like a Web Service with REST endpoint . It receives the summary and updates the custom field on VoiceCall object.

Here’s an example Apex class:

Testing the Post-Call Summary Integration

To validate that your Lambda function and the Salesforce Apex REST endpoint are working correctly, you can use Postman as a testing tool.

• Use the same REST endpoint exposed in your Salesforce Apex class:

• Add Authorization Header
• Pass JSON Body

• Send the Request : If everything is configured correctly, you should see a 200 OK response and the corresponding update reflected on the VoiceCall record in Salesforce.
