Key Concepts¶
Envelopes¶
An envelope is a container for documents and recipients. Envelopes progress through states: CREATED → IN_PROGRESS → SUCCESS or VOIDED.
Recipients¶
Recipients are the individuals who need to sign, approve, or receive documents. Each recipient has a unique access token for security.
Validations¶
Email validation provides 2FA security by requiring recipients to verify their email address with a code before accessing documents.
Webhooks¶
Webhooks enable real-time notifications when events occur (envelope sent, signed, email validated, etc.).
