Requires a Slack member access token and If-Match from the latest preview. 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.

Header Parameters

If-Match

required

string

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
