CMS service API
Docusign requires that TSPs return signed documents using CMSs ( Cryptographic Message Syntax). TSPs can build CMSs on their own. They can also use the CMS service API to delegate the creation of the CMS to Docusign.
The CMS service API does not belong to the eSignature REST API, but has its own API with the following base URLs:
- eu-sigadapter.docusign.net | Europe
- na-sigadapter.docusign.net | North America
- au-sigadapter.docusign.net | Australia
- ca-sigadapter.docusign.net | Canada
To delegate the creation of the CMS to Docusign you must first get the signed attributes using the
POST SignedAttributes method. Next, you must use the
POST cms endpoint to pass the required information, including the signed attributes, to Docusign which returns a proper CMS.
You authenticate in the CMS API using the same token you provided to authenticate in the TSP API.
