Where would you like to go?
Permissio documentation is split into two sections. Pick the one that matches what you're trying to do.
Developer Docs
Explore the Permissio REST API — authentication, the envelope lifecycle, webhooks, idempotency, and a fully interactive API reference.
User Manual
Learn how to send envelopes, manage documents, build reusable templates, and configure your account — all from the Permissio web app.
Send an envelope in 5 calls
Upload, attach signers, place fields, send, and stream events. The whole envelope lifecycle is documented end-to-end.
One host, two key prefixes
Sandbox and production share https://sign.permissio.us/api. Switch environments by sending an sk_test_… or sk_live_… key.
Webhooks you can trust
Signed payloads, deterministic retries, and an event catalog you can replay against in development.
Sending an envelope
Upload a document, add signers, place fields, and dispatch — from inside the Permissio dashboard.
Templates
Create reusable signing templates and send from them in seconds without reconfiguring each time.
The signer experience
Understand what your signers receive and how the signing ceremony works from their side.
