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
Request Bodyrequired
Section titled “Request Bodyrequired”The reviewed request revision, conflict acknowledgments and remaining-time consent for a swap response.
object
A caller-generated identifier of at most 128 characters. Reuse it only for an identical retry. A repeated operation id is recognised for 30 days; after that it is treated as a new request.

Current conflict identifiers acknowledged for the interval this caller would receive.
Keys of started intervals whose remaining time the recipient agrees to exchange. Include every preview leg with hasStarted set to true when accepting.
