Submit a library content item into an approval workflow within a specific teamsite. This initiates the approval process for the document identified by libraryContentId, routing it through the configured workflow steps so that designated approvers can review, approve, or reject the content before publication. An optional comment can be included to provide context to reviewers, and workflow attestation acknowledgments can be automatically confirmed if applicable.

When to use: Call this endpoint when a content author or library manager needs to move a draft document into an approval workflow prior to publishing. The response returns an array of workflow instance identifiers that were created as a result of the submission.

Glossary: teamsiteId — Identifier of the teamsite context for the request; may be 1 or a GUID. libraryContentId — Identifier of the library content item to submit into workflow. attestationsConfirmed — When true, required workflow acknowledgments are automatically marked as confirmed by the submitter.
