Review WhatsApp media hashes without downloading files
Keep a light-touch record of media metadata for the files your team needs to track without retrieving the files themselves.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Get media info
Get metadata about uploaded media without generating a download url. this is useful for checking file size, type, and hash without downloading the file. use get media if you need the actual download url.
Why this helps
Media reviews become slower when verifying a file requires opening or downloading every item.
- Review hashes alongside file type and size
- Avoid downloading media for basic checks
- Support repeatable media operations reviews

- 3Tell Notis which known media IDs to inspect and to report their available hashes and metadata.
- 4Choose a recurring schedule and select where run reports should go.
- 5Test with one real media ID and confirm the report includes the expected metadata.

Does the action download the file?
No. Get media info retrieves metadata without creating a download URL.
Can this discover media items?
No. The media IDs must be supplied to the workflow.
