Sign API v2 terminology
Collections and signing sessions
Our Sign API v2 has the concepts of document collections and signing sessions. A collection can contain one or more signing sessions.
- A document collection is a collection of documents that naturally belong together.
- A signing session specifies the signer and the documents they are asked to sign, along with other details such as contact details, allowed signing methods, the resulting format (XAdES/PAdES), archiving preferences, subject validation details, 'auth before sign' settings and conditional redirect URLs based on the state of the signing session.
Note
- Learn how to manage multiple documents and signing sessions with document collections in our Document collections feature guide.
- Learn more about our Document collections and Signing sessions endpoints in our API reference.

Collections and signing sessions
Signing sessions spanning several different collections
Signing sessions can include documents from several different collections. If you package a collection, it will only include the signed documents that belong to that collection, not documents from other collections signed in the same signing session.
