Undo a bulk reassignment

POST
/v1/scheduling/reassignments/{id}/undo

Gives back what a finished run moved, as a new run. A booking that's moved on since stays where it went, and a former host who's no longer free keeps it from going back, unless you pass overrides.

Authorization

bearerAuth
headerAuthorizationBearer <token>

A secret API key from the dashboard: coss_live_… for production environments, coss_test_… for sandbox environments.

Path Parameters

id*string

The reassignment's id.

Header Parameters

The API version (a date) to use for this request. Defaults to your organization's version, pinned to the latest one when it first used the API and upgraded from the dashboard. The SDK always sends the version it was built for.
