Frequently asked questions
Everything you need to know about SignPad and document signing.
What is SignPad and how does it work?
SignPad is an online contract signing and online agreement signing platform. Upload a PDF, add recipients, drag-drop signature fields onto the document, and send documents for signature online. Recipients receive a secure email link and can sign directly in their browser with no account required.
What are the three signature methods available?
SignPad supports three methods in its document signing workflow: (1) Electronic Signatures for draw, type, or upload your signature for quick signing. (2) Aadhaar OTP eSign for legally binding signatures verified through UIDAI's Aadhaar OTP gateway, compliant with the IT Act 2000. (3) DSC USB Token to sign using a physical Digital Signature Certificate on a USB token via the SignBridge desktop app.
How does credit-based pricing work?
Request a quote for your expected document volume, signer count and signing methods. Confirm credit consumption, validity and the treatment of incomplete signing requests with our team.
Do my signers need a SignPad account?
No. Recipients receive a secure link via email and can sign directly in their browser without creating an account. For added security, you can enable email OTP verification before signing.
Can I use SignPad for team signing workflows?
Yes. Create an organization workspace, invite team members, assign roles (Admin, Manager, Member), share templates, and track signing activity across your team with built-in analytics.
Is there an API to integrate signing into my app?
Yes. SignPad offers a REST API for creating envelopes, adding recipients, and tracking status. Webhook events notify your system in real-time when documents are viewed, signed, or completed. For headless API-only signing, see SignLift.
Are signatures from SignPad legally valid in India?
Aadhaar eSign and certificate-based digital signatures are recognized within the Indian electronic-signature framework. The appropriate method depends on the document and the receiving organization. Check any separate stamping, registration or sector-specific requirements.
What document formats does SignPad support?
SignPad works with PDF documents. Upload any PDF, place signing fields, and send for signatures. The signed output is a standard PDF with embedded digital signatures that can be verified by a PDF reader that supports signature validation.
How secure are documents in SignPad?
SignPad provides an online workflow with recipient authentication and signing records. Ask our team for the current security and retention details for your deployment and signing method.
Can I set the signing order for multiple recipients?
Yes. You can set sequential signing order (Signer 1 must complete before Signer 2 gets notified) or parallel signing (all signers are notified at once). You can also mix both modes within the same envelope.
