Webhook endpoint URL rejected (webhook_url_rejected)

• HTTP status: 422
• Problem type URI: https://nowgetitdone.com/docs/api/problems/webhook-url-rejected

What it means

A webhook endpoint URL failed the safety checks: it must be https on port 443 and must not resolve to a private or internal address.

Likely causes

• The URL used http, a non-443 port, or a private/loopback host.
• The host resolved to a blocked (SSRF-risk) address.

How to fix

• Use a public https URL on port 443.
• Point the endpoint at an internet-reachable host, not an internal one.
