Is it possible to get a second pair of eyes on this EventBridge event pattern? I’m trying to capture Conversations.Message.V1 events from Genesys Cloud in my AWS account, but the rule simply never triggers, even though I can see the events flowing through the Genesys Cloud webhook console without errors.
I have configured a Genesys Cloud webhook pointing to my AWS EventBridge custom endpoint. The webhook is active, and Genesys reports successful HTTP 200 responses for every message event. However, my downstream Lambda function never receives the invocation. I suspect the issue lies in the strict matching logic of the EventBridge rule pattern.
Here is the rule pattern I am using:
{
"detail-type": ["Conversations.Message.V1"],
"source": ["genesys.cloud"],
"detail": {
"conversationId": ["*"]
}
}
My environment details:
- Genesys Cloud Org ID:
prod-1234
- AWS Region:
us-east-1
- Lambda Runtime:
python3.9
I have verified that the source field in the raw payload matches genesys.cloud exactly. The detail-type appears to be correct based on the documentation. I even tried broadening the pattern to just match the source:
{
"source": ["genesys.cloud"]
}
Even with this broad rule, no events are delivered. This suggests the issue might not be the pattern matching itself, but rather how Genesys Cloud formats the payload when sending to EventBridge versus a standard HTTP endpoint. Is there a specific header or payload structure required for EventBridge that I am missing in the webhook configuration? I am using the default webhook template provided by Genesys. Any insights into debugging the exact payload structure received by EventBridge would be appreciated.
It’s worth reviewing at the event source arn and the detail-type matching. i’ve seen this exact issue where the webhook fires, but the event pattern is too strict or the source identifier is wrong. genesys cloud sends events with a specific source format, not just genesys. in the eventbridge rule, ensure the source is set to aws.partner/genesys/... or check the exact detail-type string.
here is a working event pattern for Conversations.Message.V1:
{
"source": [
"aws.partner/genesys/genesyscloud/your-account-id"
],
"detail-type": [
"Genesys Cloud Conversation Message Event"
],
"detail": {
"eventType": [
"Conversations.Message.V1"
]
}
}
if you are using a custom endpoint, the source might differ. check the raw payload in the gen webhook logs. copy the source field exactly. also, verify the detail object structure. sometimes the eventType is nested differently depending on the api version.
another gotcha: the eventbridge rule might be processing the event, but the target lambda is failing silently. add a cloudwatch logs subscription to the rule itself to see if the event is actually matching. if the rule doesn’t fire, it’s a pattern match issue. if it fires but nothing happens, check the lambda permissions.
also, make sure the webhook in genesys cloud is configured to send the raw json, not a transformed payload. if you are using a data action to transform it, the structure changes, and the event pattern breaks. keep it raw for testing. once it works, you can add transformations.
this is similar to the twilio function calls i ported. the payload structure is rigid. if you change one field, the whole integration breaks. be precise with the json paths.
Have you tried bypassing the EventBridge pattern matching entirely?
Cause: AWS EventBridge often drops Genesys payloads if the source or detail-type strings do not match the exact casing and namespace provided in the webhook payload.
Solution: Use a Rust Tokio WebSocket client to consume the Notification API directly, which gives you full control over event filtering without AWS schema constraints.
use tokio_tungstenite::connect_async;
use futures_util::StreamExt;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let (ws_stream, _) = connect_async("wss://api.mypurecloud.com/api/v2/notification/events?events=routing.queue.events&access_token=YOUR_TOKEN").await?;
let (_, mut read) = ws_stream.split();
while let Some(message) = read.next().await {
let msg = message?;
if let tungstenite::Message::Text(text) = msg {
println!("Raw Event: {}", text);
}
}
Ok(())
}
