I have a webhook endpoint set up in Genesys Cloud to receive routing events. The target service is a Python FastAPI app running on AWS ECS. Sometimes the downstream service gets overwhelmed and returns a 502 Bad Gateway. Genesys Cloud retries the delivery, which adds more load, and eventually the queue backs up completely.
I need to implement a dead letter queue (DLQ) pattern. When the API returns a 5xx error, I want to stop the retries from Genesys and push the payload to an SQS queue for later processing.
Here is my current webhook configuration in Genesys Admin:
Endpoint: https://api.myapp.com/webhooks/genesys-routing
Method: POST
Payload Format: JSON
In my Python code, I am catching the errors like this:
from fastapi import FastAPI
import requests
app = FastAPI()
@app.post("/webhooks/genesys-routing")
def handle_event(body: dict):
try:
# Process logic here
process_event(body)
return {"status": "ok"}
except Exception as e:
# This returns 500 to Genesys, triggering retries
raise HTTPException(status_code=500, detail=str(e))
The problem is Genesys Cloud keeps retrying for 5 minutes. I cannot change the retry settings on the Genesys side easily because we use this pattern for many webhooks. I need the consumer to handle the failure gracefully.
Is it possible to return a specific status code that tells Genesys to stop retrying? Or should I just catch the exception, push to SQS, and return 200 OK even if processing failed?
I tried returning 200 OK with a message saying “failed”, but Genesys marks it as successful and I lose the data if I don’t save it first. I need a way to tell the platform the delivery was received but the business logic failed.
Also, the payload contains sensitive data so I can’t just log it. I need to ensure it goes into the DLQ securely.
Any code examples for handling this in Python? I am using boto3 for SQS. The main goal is to stop the retry storm while keeping the data safe. I don’t want to lose events during peak hours.
The current setup is causing timeouts and I am seeing a lot of 502s in the CloudWatch logs. I need a reliable way to decouple the webhook delivery from the processing time.
I am not sure if Genesys Cloud supports custom headers for retry control. I checked the documentation but it only mentions success and failure codes.
Help with the exact implementation would be great. I am stuck on the logic flow.
I tried returning 404 but that also triggers retries. What is the standard practice here?
