[Production] Elevated API Errors Creating New Transfers

Incident Report for Dwolla

Resolved

We have resolved the issue causing elevated API error rates and 500 errors that began at approximately 4:09 PM CT. Some transfer requests during this period resulted in a 500 status code. For clients using idempotency-keys, retrying these requests might initially return a ‘409 Conflict’ error. This is due to Dwolla’s 24-hour idempotency key lock.

To ensure your transfers were processed correctly:
1. Check the Dashboard/API: Verify if the affected transfers were successfully created. If they weren’t, proceed to the next step.
2. Retry with a New Idempotency Key: If the original request resulted in a 500 and subsequently a 409, retry the request using a new idempotency key. This is the recommended approach.
3. Retry with Original Idempotency Key (After 24 Hours): Alternatively, you can retry the original request (with the same idempotency key) after the 24-hour lock expires. This will eventually return a ‘201 Created’ response if the transfer was ultimately successful.

If you continue to experience issues or have any further questions, please reach out to us at support@dwolla.com. We apologize for the inconvenience.
