Issue
When sending events to a Webhook destination in Segment, you may encounter a 502 Bad Gateway error where delivery attempts fail. This results in no events being successfully delivered to your configured endpoint.

Twilio Segment
Environment
Segment Console
Cause
A 502 Bad Gateway error indicates that the receiving server or an upstream gateway is unable to properly route the incoming traffic. This can occur if the destination endpoint is unavailable, misconfigured, or no longer in use.
Resolution
To troubleshoot and resolve this error, follow these steps:
- Check the health and configuration of the destination endpoint receiving the webhook events.
- Review your server logs for errors or connectivity issues that may be causing the
502responses. - If the endpoint is no longer needed, disable or remove the destination from the Segment Console to prevent further delivery attempts and errors.
- Use the Event Delivery tab in the Segment Console to review specific error details and sample event payloads for further troubleshooting.
Additional Information
- Regularly review and update your destination configurations to ensure only active and monitored endpoints are enabled.
- Disabling unused destinations helps prevent unnecessary error notifications and failed delivery attempts.
