# docusign connect webhook listener 500 retry failed

## TL;DR
Your listener is doing real work synchronously and throwing, so Connect retries until it gives up. Reproduce the failure with the logged payload, fix the handler bug, and restructure the listener to return 200 immediately while queueing the work asynchronously. Then republish the failed envelopes from Connect and confirm clean delivery in the logs.

docusign connect webhook listener 500 retry failed
```

## Use this when

- DocuSign Connect deliveries fail with 500 and eventually stop retrying
- The Connect failure log shows the same envelopes failing repeatedly
- Some event types process fine while others always 500

## Not for this skill when

- Connect never configured or pointing at the wrong URL (setup issue)
- Events deliver with 200 but your app ignores them (handling logic)
- Authentication failures on mutual TLS (transport, not handler)

## Steps

### Step 1: Read the Connect failure log

In DocuSign Admin's Connect section, open the failures for the affected envelopes and note the event types. Expected: you know which event types fail and which succeed.

### Step 2: Reproduce with the logged payload

Capture a failing payload and run it through your handler locally. Expected: you reproduce the 500 and find the bug: null field, unhandled event type, or bad parsing.

### Step 3: Fix the handler bug

Fix the null handling, add the missing event type branch, or correct the parsing. Expected: the failing payload processes cleanly in the local repro.

### Step 4: Acknowledge fast, process async

Change the listener to validate minimally, return 200 immediately, and queue the heavy work for a background worker. Expected: the endpoint responds in milliseconds regardless of payload.

### Step 5: Republish and confirm

Use Connect's republish for the failed envelopes, or wait for the next retry, and watch the delivery log. Expected: deliveries show success and stay successful.

## Tool compatibility

DocuSign Connect (webhooks); DocuSign Admin Connect logs and republish; background job queues for async processing.

## Variant phrasings

### Variant 1

docusign connect webhook 500 internal server error

### Variant 2

docusign connect retry failed listener error

### Variant 3

docusign webhook events failing 500 envelope

## Why it happens

DocuSign Connect treats any non-2xx as a failed delivery and retries with backoff, then eventually parks the envelope as failed. The 500s almost always come from handlers that do too much synchronously: parsing the full envelope, calling other APIs, writing to a slow database, all inside the request, where any exception becomes a 500. The retry loop then multiplies the damage by re-running the same doomed work. The correct shape for a webhook listener is boring: accept, persist the raw payload, acknowledge, and let a worker do the thinking. That shape also makes the failure debuggable, because the payload is saved before anything can throw.

## Edge cases / pitfalls

- Connect keeps only a limited failure log; export failing payloads before they age out.
- Envelope XML and JSON formats parse differently; confirm which format your listener expects.
- If mutual TLS is enabled, certificate expiry fails delivery before your handler runs; check that separately.
