Creates a pending request. Duty remains unchanged until acceptance. 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 “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

A swap request, its rotation name and the actions available to this caller.
object
The participants, offered intervals and current state of a swap request.
object
