How to add the items to the check

To add items to an existing check, you send a POST request to the /orders/{orderGuid}/checks/{checkGuid}/selections endpoint. To identify the items to add, you provide a JSON array of Selection objects.

To add items to an existing check

  1. Find the Toast platform GUIDs of the order and the check that you are adding items to. For more information on locating these GUIDs, see Finding an order or check guid.

  2. Create a JSON array of Selection objects that contain information about the items you are adding, including modifiers. For an example, see Example request message body to add an item to an existing check.

  3. Send a POST request to the /orders/{orderGuid}/checks/{checkGuid}/selections endpoint of the Orders API.


    In the POST request path parameters, include the Toast platform GUIDs of the order and the check.


    In the request message body, include the array of Selection objects.

  4. Examine the response that you receive from the Orders API. Verify that your request processed successfully with a 200 HTTP code response. For an example, see Example response after adding items to an existing check.
