Create a delivery order

POST /v2/fulfillment/users/{user_id}/orders/delivery

Creates a delivery order for the reserved time slot.

If the reservation has expired, Instacart still attempts to book the time slot. If, however, the time slot capacity is filled, your site needs to prompt the customer to select another time slot. The response can take several seconds to return, so for the best customer experience, create the order as soon as possible after the customer completes your checkout process.

danger

If the items in the cart changed after a time slot was reserved, the order creation might fail. For details, see the returned error message.

Order item limitations​

If your request specifies an order containing items that exceed any of the following limitations, the order is not created:

  • Maximum total quantity of items
  • Maximum total weight of beverage items
  • Maximum quantity of large or bulky items

For more information about why an order couldn't be created, see the returned error message.

Age verification for alcohol​

Some products require age validation in accordance with regional laws, such as alcohol and over-the-counter medication. When a cart contains an age-restricted product, the retailer site must request the customer’s date of birth and include it in the order sent to Instacart. If the birthday is missing or the customer is not old enough to purchase the item, Instacart Connect returns an error or removes the item based on your configuration.

Store location​

You can specify the store location in the request. When a shopper shops for an order, they are asked to shop from the selected store location, but there is no guarantee that they shop there.
