What Permissio is
Permissio is the system of record for the envelopes your business needs signed. It is built for engineers first: the API surface is the source of truth, and every UI in the Permissio application is a thin client over the same endpoints you have access to.
The platform handles three durable concerns:
- Custody. Envelopes and their signed copies are stored, versioned, and retrievable through stable IDs.
- Identity. Each signer is bound to a verified email address (and, in production, optional stronger identity proofs).
- Audit. Every state change emits an immutable event that can be streamed to your systems through webhooks or pulled from the events API.
Permissio is not a document editor. You bring a PDF (or generate one from a template), and Permissio routes it through signing.
