get workspace changes
What has happened in the workspace, as the people in it read it in the app: files added, generated and edited, timelines and canvases worked on, folders, labels, fields, stars and hides, public links, skills and published clips, each with who did it and what it touched. A bare call returns the newest window; after_cursor returns only what is new since a next_cursor, oldest first; before_cursor reads further back. Free.
Authorizations
An API key (es_live_…) from Settings, under API keys, or an OAuth access token.
Headers
Retry a paid dispatch safely: the same key returns the job already dispatched instead of charging again.
The workspace this one call acts in, when it is not the key's own.
