Signed PDF Integrity Gate Before Dropbox Archive
When a signed PDF lands in a Dropbox intake folder, it verifies the signer name, signing date, and certificate fields.
How it runs
The automated pipeline, trigger to output.

- ActionParse embedded signature metadataShell
- LogicValidate signer, date, and certificate fields
- ActionMove valid file to Dropbox archiveDropbox
- ActionQuarantine invalid file in DropboxDropbox
- OutputPost verification outcome to SlackSlack
What it does
Watches a Dropbox "signed-intake" folder and inspects every new PDF before it reaches long-term storage. It reads the embedded signature metadata, checks that a signer is present, the signing date is within an allowed window, and the certificate has not expired, then routes the file accordingly.
When to use it
Use it when contracts or approvals come back signed and you need a deterministic gate that no unsigned, stale, or improperly-certified document gets archived as "final." Good for legal, procurement, and compliance teams who archive in Dropbox.
How it works
- 1A new file in the Dropbox intake folder triggers the run.
- 2A shell step runs a PDF signature parser and emits signer, date, and certificate fields as JSON.
- 3A logic step validates the three fields against your rules (signer non-empty, date in window, cert valid).
- 4If valid, the PDF is moved to the Dropbox archive folder with verified metadata.
- 5If invalid, it is moved to a quarantine folder and a failure reason is recorded.
- 6The outcome is posted to a Slack review channel.
