Use an action offered by the request capability. Actions are accept, decline and cancel. Acceptance exchanges both remaining duty intervals together. Cancelling accepted duty preserves completed service. Reuse operationId and the same body when retrying an uncertain result. A missing If-Match returns 428. On 412, refresh the preview before retrying.

Section titled “Path Parameters”Header Parameters
Section titled “Header Parameters”The ETag from your last read of this resource, sent back exactly as you received it, quotes included. The write happens only if nothing changed in between: a stale validator is answered 412 and nothing is written. Send * to write against whatever is current on purpose. Omitting the header is 428, never an unconditional write. https://docs.roundrobinbot.eu/api/conventions/#conditional-writes

Original holders by interval, including periods with no assignee and unresolved periods.
Effective duty during part of an assignment interval.
object
The inclusive UTC start.
Whether the holders or absence of duty are known for this interval.
The exclusive UTC end.
Slack user identifiers of the effective holders. An empty list means no assignee only when resolved is true.
The exclusive UTC end of the returned interval.

The arrangement revision used when changing or ending it.
The rotation identifier.
active or cancelled. An active record can describe an interval that has already ended.
The exclusive UTC end.
The recorded full or remaining turn, or null when no verified selection was saved. Use the arrangement’s From and To for the affected interval.

The earliest later instant at which the state, a phase, active or actionable changes by the clock alone. Null when none will.
The request.
object
The request identifier.
The offered intervals.
