ref |
Optional[str] | ➖ | A caller-supplied reference for this item, echoed back on the matching result so each outcome can be tied to the record it came from. Must be unique within the request. Never sent to the connector. | item-1 |
data |
models.BillCreateInput | ✔️ | The writable shape of Bill for a batch create. Identical to [Bill](the model returned on reads) with the read-only properties removed — the same properties the single-record create endpoint rejects, so a batched record and a single-record create accept exactly the same body. |
