What are Vonage's HTTP session time-out limits for a webhook response?


How long will Vonage wait for a 200 OK from my server?

Applies To

  • HTTP Session
  • Webhooks


The set timeout for establishing the HTTP connection is 3 seconds. The timeout for a response once the HTTP session has been set up is 15 seconds. If we establish the connection but don't receive a 200 OK within 15 seconds, we will disconnect and try again 60 seconds later. A timeout will show as '-1' response on the Dashboard Debug Tools. We will retry Inbound Message and Delivery Receipt callbacks every minute for 24 hours, and Delivery Receipt callbacks for 72 hours.
