EventBridge Rule Triggering but Genesys Webhook Payload Missing Required Fields

Hey everyone.

We are trying to sync agent state changes from Genesys Cloud to our internal WFM database using AWS EventBridge. The goal is to get real-time adherence data without polling the API every minute. We’ve set up the integration in Genesys Cloud under Integrations → Amazon EventBridge. The connection test passes, and we can see the events arriving in the CloudWatch logs.

The problem is the payload structure. The EventBridge rule triggers, but the detail object doesn’t have the agentId or state fields we need for our Lambda function. It looks like the generic platform event wrapper is stripping out the specific interaction data.

Here is the JSON payload we are receiving in the Lambda handler:

{
 "version": "0",
 "id": "a1b2c3d4-...")
 "source": "genesys.cloud",
 "account": "12345",
 "time": "2023-10-27T08:00:00Z",
 "region": "us-east-1",
 "detail-type": "Genesys Cloud Event",
 "resources": ["/api/v2/users/..."],
 "detail": {
 "eventType": "user.state.changed",
 "timestamp": "2023-10-27T08:00:00Z"
 }
}

We expected the detail object to contain the actual state change data, like userId, state, and teamId. Instead, it’s just the event type and timestamp. We’ve checked the Webhook configuration in Genesys Cloud, and we have enabled all available event types for user.state.changed.

Is there a specific setting in the EventBridge integration that controls payload depth? Or do we need to make a secondary API call to /api/v2/users/{userId} inside the Lambda to get the state? That feels inefficient if the event is supposed to be real-time.

We are using the standard AWS SDK for Python (boto3) to manage the EventBridge rules. The rule pattern is:

{
 "source": ["genesys.cloud"],
 "detail-type": ["Genesys Cloud Event"]
}

Any ideas on how to get the full payload? We don’t want to hit the API rate limits by fetching user details for every state change. It’s a high volume environment.

Check the EventBridge bus mapping. The Genesys integration sends events to a specific bus, not the default one, and the detail object is nested under detail. If you’re parsing the raw event as the payload, you’re looking at the envelope, not the data.

The payload structure looks like this:

{
 "id": "...",
 "source": "com.genesys.cloud",
 "account_id": "...",
 "time": "...",
 "region": "...",
 "detail-type": "Genesys Cloud Event",
 "resources": [],
 "detail": {
 "eventType": "agent:state:change",
 "accountId": "...",
 "data": {
 "id": "...",
 "state": "available",
 "timestamp": "..."
 }
 }
}

Your rule needs to filter on detail.eventType and then map detail.data to your target. If you’re using a Lambda, extract event.detail.data before processing. Don’t assume event.body or similar structures. EventBridge doesn’t wrap it in a body field.

Here’s a quick Node.js handler snippet to verify the structure:

exports.handler = async (event) => {
 console.log('Received event:', JSON.stringify(event, null, 2));
 
 const payload = event.detail?.data;
 
 if (!payload) {
 console.error('Missing detail.data in event');
 return { statusCode: 400, body: 'Invalid payload' };
 }
 
 // Process payload here
 console.log('Agent state:', payload.state);
 
 return { statusCode: 200, body: 'OK' };
};

Make sure the EventBridge rule filter matches the detail-type exactly: Genesys Cloud Event. Case sensitive. Also check that the integration in Genesys is publishing to the correct bus. If it’s sending to a custom bus, your rule must be on that bus. Default bus won’t catch it.
