Carts

Add Cart Line Items

POST /carts/{cartId}/items

Request

Adds line item to the Cart.

Usage Notes

To add a custom item use custom_items.

Overriding a product’s list_price will make that item ineligible for V3 product level promotions.

If a product has modifiers, omit the variant_id and instead use the option_selections array to describe both the variant and the modifier selections.

Please note that this API endpoint is not concurrent safe, meaning multiple simultaneous requests could result in unexpected and inconsistent results.

Update Cart Line Item

PUT /carts/{cartId}/items/{itemId}

Request

Updates an existing, single line item in the Cart.

Notes

Currently, only updating list_price and quantity are supported. Updating a product’s list_price will make that item ineligible for V3 product-level promotions.

If the product has modifiers, omit the variant_id and instead use the option_selections array to describe both the variant and the modifier selections.

If a variant needs to be changed or updated, the product will need to be removed and re-added to the cart with the correct variants using the Add Cart Line Items endpoint.

custom_items cannot be updated via the API at this time. To update your cart, add a new updated custom item and delete the outdated one. If your cart contains only one line item, perform the add operation before the delete operation.

Deleting all line items from the cart will invalidate the cart.

Please note that this API endpoint is not concurrent safe, meaning multiple simultaneous requests could result in unexpected and inconsistent results.
