What you need to know
Distinguish a missing tag from a server-side error and from an ordinary authentication response.
Step by step
- Confirm the full VAST URL was copied, including its public identifier.
- Check that the commercial or saved tag still exists and is active.
- Try a simple commercial tag to isolate a saved-tag or pod-specific issue.
- If an HTTP 500 occurs, inspect the server PHP error log or contact support with the time and URL.
- For API requests, include a valid Bearer token; a missing-token JSON error is not a VAST error.
Tips and common mistakes
- Do not paste private API keys into the VAST tag URL.
- If an issue began after an upload, restore only the affected file from a backed-up version.
