Frequently asked questions
How do I embed signing in my app?
Use PandaDoc’s SDKs or an iframe to drop the signing experience directly into your product. This keeps users in your workflow while PandaDoc handles the secure signing process behind the scenes.
Are signatures collected with the API legally binding?
Yes. Documents signed through the PandaDoc E-Signature API comply with ESIGN, UETA, and eIDAS regulations. You also get a complete audit trail for every transaction to meet compliance requirements.
How do I monitor the progress of a signature request?
The API provides webhooks for every key event — sent, opened, signed, or declined. You can use these callbacks to update your UI in real time or trigger follow-up workflows in your CRM or backend systems.
Can I automatically retrieve signed documents?
Yes. Once a document is completed, you can use the API to download the signed .pdf along with its audit trail. Many teams archive these automatically in their CRM, storage system, or custom repository.
Can we automate follow-ups?
Yes. You can set document expirations and use API endpoints to send manual reminders or manage auto-reminder settings.
