Queue template send job
Accepts a bulk template send and processes it in the background. The request is validated at the door, queued durably, and returns 202 Accepted immediately with a job id. Send an Idempotency-Key header to make retries safe: repeats of the same key within seven days return the original job id instead of sending the batch again. Without the header, Flowella derives a key from the request body, so an identical batch submitted twice in quick succession is not double-sent. Recipients are processed individually, so one invalid number does not block the rest of the batch.
Authorizations
Organization API key (flo_…). Paste the full key; Scalar sends Authorization: Bearer <key>.
Headers
Unique key (up to 200 characters) identifying this batch. Repeats of the same key within seven days return the original job id without re-sending. If omitted, Flowella derives a key from the request body.
