webhook_url_invalid
HTTP 422 · Do not retry unchanged — fix the request first
The webhook URL is not a usable https address.
What happened
Webhook payloads carry order data, so plain http:// is refused.
URLs with embedded credentials are refused as well.
How to fix it
- Use a plain
https://URL without a username or password in it.
Retrying
Repeating the request unchanged will fail again. Correct the request first — the response tells you which part is wrong.
