Errors

The Updatify API uses standard HTTP status codes to indicate the outcome of a request.

Status codes

Status	Meaning
200 OK	The request succeeded.
401 Unauthorised	The token is missing, malformed, invalid, or revoked.
404 Not Found	The resource doesn’t exist, or it isn’t owned by your account.
422 Unprocessable Entity	The request was understood but couldn’t be processed (e.g. invalid parameters).

Authentication errors

Failed authentication on a protected endpoint returns 401 with a plain-text body:

HTTP/1.1 401 Unauthorized

Unauthorised

If a token that used to work suddenly returns 401, it has most likely been revoked, or the account’s email address changed (tokens are bound to the email they were issued for). See Authentication.

JSON error bodies

Errors raised while processing a request return a JSON body. The exact shape depends on the endpoint:

{
  "errors": { "details": "Unauthorised" }
}

The track endpoint reports failures with a success flag instead:

{
  "success": false,
  "errors": "Update not found"
}

Tips

• A 404 on List project updates most often means the token belongs to a different account than the project — double-check the project id.
• Repeated 401s usually mean the token was revoked or the account email changed. Generate a new token from the API tokens page.
