The DocuSign Connector supports the following signature methods:

Simple e-signature

  • Non-embedded e-signature enables signers to complete document signatures outside the host app, typically through email or the DocuSign signing portal.
  • Embedded e-signature integrates the signing experience directly within your app, allowing signers to review and sign documents without leaving your app’s interface.

Advanced e-signature

  • Advanced Electronic Signature (AES) provides a higher level of security than standard e-signatures by requiring signers to verify their identity with a secondary authentication factor, such as a unique access code or a mobile OTP.
  • AES is also available in embedded and non-embedded variants.

Event-driven architecture

The DocuSign connector includes inbound webhook support for real-time signing status processing.

Webhook events

Grand Central processes DocuSign Connect events and transforms them into unified status values. The following table maps each DocuSign Connect event to its unified status:
