For TikTok Shop, a warehouse must be assigned on the listing first — today that's done in the dashboard (Listings → the listing → warehouse); publishing without one fails with a clear error. For Etsy/Shopify, the listing must be in DRAFT status.
Parameters
Parent listing UUID.
Send the same key when retrying this exact call. A completed request replays for 24 hours without running or billing again.
An https URL that receives a signed completion event when the work finishes, so you can skip polling. See Webhooks.
Returns
Opaque async handle. Pass to listing.get_generation.
Describes the listing.get_generation(..., wait_sec=...) contract.
