Troubleshoot webhook endpoint issues

Problem Symptoms

• In the Nylas dashboard webhook logs or via email you receive the following message: Failed to connect to the webhook endpoint
• Your endpoint replies with a 500 response

Description

We wait 10 seconds for the host to respond, there are a few reasons why the webhook endpoint might be having issues.

• IP blocked
• Network delays  or packet loss in the route
• Host CPU congestions

Resolution

You can test for packet loss / latency via traceroute or MTR to the IP of the host you entered as your webhook endpoint.

If the endpoint is replying within 10 seconds but with a non 200 response please test your endpoint by sending a sample payload.
