not_found

What it means

There is no object with that id in your app. We answer the same way for ids that exist in another app, so ids cannot be probed across accounts.

Why it happens

• The id is mistyped or from another environment (a live id with a test key, or the reverse).
• The domain was deleted. Deleted domains stop resolving immediately.
• The path itself is wrong, for example a missing /v1 prefix.

What to do

1. Check the URL against the OpenAPI document.
2. Test keys only see test domains: use the key that created the object.
3. List objects (GET /v1/domains?hostname=…) to find the current id of a hostname.
