Set deal products

PUT /v1/deals/:id/products

Sets the deal product rows. Replaces the current list as a whole — pass all the rows you need.

Field names are validated. A field name that is not in the writable set is not dropped silently: the request is rejected with 400 INVALID_PARAMS and the error text lists the writable names. Read-only fields that appear in product-row responses — priceAccount, ownerId, storeId and others — are accepted and ignored, so an object read via GET can be sent back as is.

Row identifiers do not carry over. A row whose fields are unchanged keeps its id. A modified one comes back with a new id even when the previous identifier is sent in the body. To edit a row and keep its id, use PATCH /v1/deals/:id/products/:rowId.

Known specifics

Full replacement: PUT replaces the entire product list. To add a row, first get the current ones (GET), add the new one to the array, and send everything back (PUT). Fetch the whole list: without limit, GET returns only the first page, so pass limit=5000 or page through with offset until meta.hasMore is false. Sending back an incomplete list erases everything it omits.

A fixed-amount discount requires discountTypeId: 1. The discount type defaults to 2, a percentage, and in that mode the discount field is not stored: the row comes back with discount: 0 and no error is raised. To set a discount as an amount, send discountTypeId: 1 together with discount. To set it as a percentage, send discountRate with type 2.
