5 hooks x 5 offers x 4 ratios = 100: one weekly bulk queue

Five hooks times five offers times four ratios is 100 items, which is the largest bulk queue Sume accepts. Build the matrix in a script, send it as one POST …/bulk-runs with concurrency up to 16, and map results back by item index.

Build the 100 items

Each item is the same body as a single Format run. It must name at least one of instruction, input, previous_run_id or attachments. Put the combination in the instruction and in input so the child sees it.

Create a lookup of index to hook, offer and ratio. The queue returns items[] in the same order, with index, status, run_id and error.

Order matters

Items start in the order you send them, so put the 9:16 combinations first if that is your main placement. With concurrency: 16, items 0 to 15 start straight away and 84 wait.

If you need 6 hooks, 100 is not enough: 6 x 5 x 4 is 120. Split into two queues and use a different Idempotency-Key for each.

Read the results

The queue is completed when every item is terminal, not when every item succeeded. Check counts.failed and counts.canceled, then read the child receipt for the reason a child failed. The queue has no webhook; poll status_url, or register a webhook on each item.
