Configured the EventBridge rule in AWS console with source genesys.cloud and detail-type genesys.cloud.api.events. The rule matches and triggers the Lambda, but event.detail is always null.
{
"version": "0",
"id": "abc-123",
"detail-type": "genesys.cloud.api.events",
"source": "genesys.cloud",
"account": "123456789",
"time": "2023-10-27T12:00:00Z",
"region": "us-east-1",
"resources": [],
"detail": {}
}
Docs say the event bus should receive the full payload. Is this a permissions issue or do I need to set a specific detail filter?
You’re seeing an empty detail object because the EventBridge rule is matching the source, but the actual event data isn’t being pushed or parsed correctly. Genesys Cloud events sent to SNS/SQS often require explicit filtering or the target needs to handle the base64 encoding if you’re using SQS. If you’re using SNS to EventBridge, make sure the MessageAttributeFilter in your SNS subscription is set correctly.
Check your Lambda handler. Sometimes the payload is nested deeper than expected. Try logging the raw event object, not just event.detail. Also, verify that the Genesys Cloud event subscription is actually active and sending data. You can test by triggering a test event in Genesys Cloud Admin > Platform > Event Subscriptions. If the SNS topic receives it, the issue is in the EventBridge rule configuration or the Lambda parsing logic.
{
"detail-type": ["genesys.cloud.api.events"]
}
The suggestion above touches on filtering, but the real issue here is usually how the event payload is constructed in the Genesys Cloud integration settings. Docs state: “EventBridge receives a standardized envelope. The detail object contains the specific event data defined by the source.” If detail is empty, the source isn’t sending the payload correctly, or the event type isn’t fully supported in the current integration version.
Check your Genesys Cloud integration configuration. Specifically, look at the “Event Types” section. Are you subscribing to the correct granular event? Often, genesys.cloud.api.events is a broad category. You might need to subscribe to something more specific like genesys.cloud.conversations.call or genesys.cloud.users.login depending on your use case.
Also, verify the target configuration. If you’re using SNS as an intermediary, ensure the message attributes are being passed through. EventBridge doesn’t automatically parse SNS message bodies unless configured to do so.
Here’s a quick check for your Lambda handler to see what’s actually arriving:
import json
def lambda_handler(event, context):
print(json.dumps(event, default=str))
if not event.get('detail'):
print("Detail is empty. Check Genesys integration event types.")
return {
'statusCode': 200,
'body': json.dumps('Detail missing')
}
# Process event.detail here
return {
'statusCode': 200,
'body': json.dumps('Event processed')
}
If the print statement shows the full event but detail is still {}, then it’s definitely a configuration issue on the Genesys side. Double-check the “Event Types” in your integration. Make sure you’re not just subscribing to the top-level category. Some events don’t push data into detail by default. You might need to enable “Include Event Data” or similar option in the integration settings.
