Questions about e-sign and digital documents
What is the difference between an electronic signature and a digital signature?
An electronic signature is any electronic indication of intent to sign. Under the IT Act, a digital signature uses a certificate issued by a licensed Certifying Authority, and Aadhaar based eSign lets a person sign with an OTP through an eSign service provider. Which one a contract needs depends on the document type and the counterparty.
Which Indian providers offer e-sign APIs?
The directory lists Leegality, Digio, SignDesk, Signzy, Gridlines, Cashfree Secure ID, Setu, QSign and Protean eSignPro, among others. Docs are public for several of them, for example Leegality, Digio, Setu and QSign. Prices are mostly not published, except QSign, which lists monthly plans.
Can I buy e-stamp paper through an API?
Some providers document it. Setu lists eStamp in 20 or more states and union territories, Legistify documents an e-stamping API through SHCIL, and esahayak lists a stamp API on a prepaid wallet. Availability depends on each state's e-stamping system, so confirm your state and document type first.
Are e-sign providers scored on JurisGrid?
No. E-sign tools are workflow infrastructure rather than data products, so they are profiled without a numeric score. Identity verification APIs from the same vendors, such as KYC checks, are scored in the background verification sector when public evidence supports it.
What should I check before integrating an e-sign API?
Check public API docs and a sandbox, supported signing modes such as Aadhaar eSign or DSC, audit trail and certificate output, pricing per signature, and whether you can sign up without a sales call. Confirm legal validity for your document class, since some documents may need stamping or physical execution.
