Verify a Deliverable

Verify deliverable authenticity using Adobe Acrobat Reader’s digital signature validation

To verify that a deliverable was generated by SignatureAPI, open the PDF in Adobe Acrobat Reader (free) or Adobe Acrobat (paid).

1. Check the signature status.
   Look for a green check mark next to the signature icon. You should see the message:
   “Signed and all signatures are valid.”

   

2. Open the Signature Panel.
   Review the signature details.

All SignatureAPI deliverables are signed with a digital certificate issued to Signature API, Inc.
To view the certificate’s serial numbers and fingerprints, go to the API verification guide.
