# Multiple Line Items

Submit purchase orders with more than one line item using the indexed LI_ parameters.

The Payment Service supports purchase orders with more than one line item. Use the Line Item Parameters: `LI_PROD_ID_X`, `LI_COUNT_X`, and `LI_VALUE_X`. The "X" indicates a dynamic number depending on how many line items you want to send.

| Parameter | Description |
|---|---|
| `LI_PROD_ID_X` (required) | Product ID for the line item. Replace 'X' with an incrementing integer. |
| `LI_COUNT_X` (required) | Quantity for the line item. Max value is 99. |
| `LI_VALUE_X` (required) | Transaction Amount for the line item. |


Capturing a single line item later (partial shipment, split fulfillment) uses `captureLineItem(order, lineItemRef, amount)` in all four SDKs, taking a `LineItemRef` from `result.lineItemRefs` (or `result.line_item_refs` in Python) rather than a raw `PO_LI_ID` string.
