not_found

HTTP 404. The thing you named does not exist, or does not exist on this account.

404 — unknown template

{
  "error": {
    "type": "not_found",
    "message": "Template `invioce` was not found on this account.",
    "docs_url": "https://galleyrender.com/docs/errors/not_found",
    "details": {
      "requested": "invioce",
      "available_templates": ["invoice@1", "og-card@2", "receipt@1"],
      "create_url": "https://galleyrender.com/docs/templates#create"
    }
  }
}

404 — unknown version

{
  "error": {
    "type": "not_found",
    "message": "Template `invoice` has no version 7.",
    "docs_url": "https://galleyrender.com/docs/errors/not_found",
    "details": { "latest_version": 3 }
  }
}

Why this happens

Raised when	Endpoint
No template with that name, or it was deleted	render, get, version publish, version list, delete
The template exists but has no such version	anything taking name@N
No render with that id on this account	GET /v1/renders/:id
The URL matches no route at all	anything — details.docs points at the API reference
A stored object is missing behind a valid render row	file delivery

Everything is scoped by account. Somebody else’s id is a 404 by design, so the API never confirms that an id exists elsewhere.

How to fix it

When a template is missing, details.available_templates already lists up to 25 that do exist, in name@version form — pick from it rather than guessing, or list them with GET /v1/templates. When a version is missing, details.latest_version tells you how high the numbers go. Remember that a deleted template stops resolving immediately, while renders it produced keep working.

Does retrying help?

No, unless you are polling for something that has not been created yet.
