What is Subnoto?
Section titled “What is Subnoto?”Subnoto is an electronic signature platform you integrate via API: your backend creates envelopes (upload documents, add recipients and signature blocks, send), and you can either embed the signing UI in your own app (iframe + token) or let signers use Subnoto-hosted links. Signing runs in a secure enclave; you get webhooks on events and can download the signed PDF plus a tamper-proof audit proof when the envelope is complete.
