Orders API

What It Does

Create, track, and manage orders in your web and mobile applications.

Overview Permalink Get a link to this section

The Orders API integrate parts of the Square ecosystem to track and manage the lifecycle of a purchase. The API can record purchase items, calculate totals, confirm payment, track an order's progress through fulfillment, and update a catalog inventory.

With the Orders API, you can build web and mobile applications that use orders to manage purchase item information, track order fulfillment, integrate customer data, and link payments. You can also create fulfillment orders and send them to the Square Point of Sale application for fulfillment.

Orders components Permalink Get a link to this section

The Orders API works with the following key data types:

  • Order. The top-level container for order information. Order objects include fields for line item details, fulfillment details, and order summary data, including the location ID credited with the order and the total amount of taxes collected.

  • OrderLineItem. Represents a purchase item (for example, a coffee or T-shirt). Each line item has a OrderLineItemModifier that represents an available size or color. Items and modifiers can be built from Catalog objects or they can be defined ad hoc (at the time of creation).

  • OrderLineItemDiscount and OrderLineItemTax. A price modifier that can be applied at the order or line item level. Taxes and discounts can be configured as Catalog objects and referenced in the order or they can be created ad hoc.

  • OrderFulfillment. Contains details about how to fulfill this order, such as the customer name or the time at which the customer should pick up the order. Order objects made with fulfillments are pushed to the Square Seller Dashboard when charged, so sellers can manage order fulfillment in the Square Point of Sale application.

  • OrderSource. Tracks the digital or physical source of the order. Orders can be searched or retrieved by the source.

Integrating with the Orders API Permalink Get a link to this section

The Orders API integrates seamlessly with other Square APIs and resources to expand the functionality of your application.

Square Point of Sale Permalink Get a link to this section

Orders with fulfillment that have been fully paid are pushed to the Square Point of Sale application, so that sellers can manage fulfillment with the Square Point of Sale application. The Orders API currently supports two types of fulfillment orders: Pickup and Shipment. For more information, see Add fulfillment details.

Payments Permalink Get a link to this section

Link your payments to Order objects to itemize sales and apply price modifiers such as taxes, discounts, and service charges. You can also use the Orders API to retrieve any payment activity associated with a sale, whether from the Square Point of Sale application, invoices, or an integration build with the Payments API and Orders API. For more information, see Pay for Orders.

Catalog Permalink Get a link to this section

Line items, line item modifiers, taxes, and discounts can all be defined as catalog objects. The Orders API reaches its full range of capabilities when orders are built using Square catalog objects.

Key advantages to using catalog items include:

  • Orders that reference catalog IDs for taxes and discounts are automatically calculated and applied these price modifiers.

  • Orders that reference catalog line items use details defined in the catalog, such as the item name and price.

  • When these orders are closed, Square updates the inventory for those items.

Take some time to set up your catalog with the Catalog API to unlock the full range of capabilities from the Orders API. For more information, see Create Orders.

Did you know?

Orders can also be built from ad hoc line items defined at the time of Order object creation. You need to supply an item name and price.

Customers Permalink Get a link to this section

Order objects can reference a customer profile. You can later use SearchOrders to search orders by customer. For more information about making customer profiles, see Use the Customers API.


The Orders API integration with the Customers API is in beta. For more information about known beta issues, see the changelog.
