75300 – Webhook host returned HTTP 3XX

undefined

75300 – Causes ​

  • The webserver may be redirecting HTTP to HTTPS, vice-versa, or between subdomains.
  • Some applications may attempt to normalize trailing slashes, redirecting clients.
  • A firewall may be redirecting connections not on your network.

75300 – Solutions ​

  • Set the webhook URL to the normalized form your application prefers after all redirects. Using a command like curl -i http://mywebhook.example.com/url/path can reveal redirects.
