Product recommendations extension reference
This reference topic describes the fields that Shopify sends to your app for each of the Shopify Point of Sale (POS) product recommendations app extension endpoint calls. The reference topic includes the response fields and possible values for the templates and actions that your app sends to Shopify.
Request fields
Anchor link to section titled "Request fields"Every request that Shopify sends to your app's extension endpoints contains the request_uuid field:
| Name | Type | Required | Value |
|---|---|---|---|
request_uuid |
String | ✓ | Shopify's unique identifier for the current request for recommendations. This identifier will be provided in all subsequent recommendations_shown and action_taken requests so your app can reconcile these events to the recommendations it provided. |
Requests sent to the recommendations endpoint and the action_taken endpoint also contain the fields described below.
The recommendations request fields
Anchor link to section titled "The recommendations request fields"Each request to the recommendations endpoint includes the following fields:
| Name | Type | Required | Value |
|---|---|---|---|
surface |
String | ✓ | The surface from which these recommendations will be shown. Possible values: ["cart", "customer_profile", "product_details"] |
customer_id |
Number | ✓ | Shopify's unique identifier for the customer on the cart if the surface is "cart", or the identifier of the customer who's profile is being viewed if surface is "customer_profile". Otherwise, the value will be null. |
locale |
String | ✓ | Used to translate any textual data into the correct language for the POS staff member. Example values: en-US, en. |
supported_templates |
Array | ✓ | Defines a set of data and how that data is rendered in the POS client. Possible values: ["grouped_product_variant_list"]. |
elements |
Array | ✓ | The list of elements in the cart if the surface is "cart", or a single element list of the product being viewed if the surface is "product_details". Otherwise, the value will be null. Each element in the list has a product_id if the surface is "product_details", or both a product_id and variant_id if the surface is "cart". |
The action_taken request fields
Anchor link to section titled "The action_taken request fields"Shopify might send multiple action_taken requests for the same request_uuid. For example, if multiple products from the same request are added to a cart, then you receive a separate request for each product. The same applies for order_created requests.
Each request to the action_taken endpoint includes the following fields:
| Name | Type | Required | Value |
|---|---|---|---|
action |
String | ✓ | The action that was taken by the user. Possible values: ["added_to_cart", "order_created"] |
order_id |
Number | Shopify's unique identifier for the order that was created. If action is "added_to_cart", this value will not be included in the request. |
|
elements |
Array | ✓ | The list of recommended elements that were added to the cart. Returns nil for "order_created" actions. Each element in the list has a product_id and possibly a variant_id corresponding to a recommended product or product variant. |
Response fields
Anchor link to section titled "Response fields"In response to the recommendations request described above, your app returns the template and recommendations that should be displayed to the user. Currently, the only supported template is grouped_product_variant_list.
After a request to the recommendations endpoint, your app must provide the following fields in the response:
| Name | Type | Required | Value |
|---|---|---|---|
template |
String | ✓ | The chosen template. Must be "grouped_product_variant_list" |
title |
String | ✓ | The text that will be displayed on the tile prompting the users to view the full recommendations details. |
groups |
Array | ✓ | An array of recommendations grouped by a title. Each object has the following fields:
groups.
|
HTTP status responses
Anchor link to section titled "HTTP status responses"The status code for the recommendations requests should return 200. If no recommendations are available, then return an empty array for elements. If an unexpected status code is received, then Shopify POS displays an error to the user.
The status code for the recommendations_shown and action_taken requests is ignored because Shopify POS doesn't need any information from the response to these requests.
