Add members to signing group
Authentication
OAuth 2.0 access token (JWT or auth-code grant). Sent as
Authorization: Bearer <token> on every request except
GET /v2.1 and GET /service_information, which are
public discovery endpoints.
Path parameters
The external account number (int) or account ID Guid.
The ID of the signing group.
Note: When you send an envelope to a signing group, anyone in the group can open it and sign it with their own signature. For this reason, Docusign recommends that you do not include non-signer recipients (such as carbon copy recipients) in the same signing group as signer recipients. However, you could create a second signing group for the non-signer recipients and change t he default action of Needs to Sign to a different value, such as Receives a Copy.
