Manage modifier groups and modifiers

In restaurants and online ordering services, merchants use modifier groups and modifiers for customizing orders. These modifiers help restaurant kitchens to receive all the required details for an order. Clover Register, Counter Service, and Table Service apps in the US and Canada all support modifiers, modifier groups, and variants.

For example, in a Salad Add-in modifier group, you can have modifiers like Tofu and Avocado. In the Clover Register app, merchants can customize a Caesar Salad item with two Tofu modifier and three Avocado modifier additions.

With the REST API, you can build custom solutions to create, manage, and query modifier groups.

Create a modifier group

  1. Send a POST request to /v3/merchants/{mId}/modifier_groups.
  2. Enter required information—name value.
  3. Enter additional values—minRequired and maxAllowed for modifier limits that can be associated with order line items in the Clover Register app.
curl --request POST \
--url 'https://sandbox.dev.clover.com/v3/merchants/{mId}/modifier_groups' \
--header 'content-type: application/json' \
--header 'Authorization: Bearer {access_token}'
--data '{"name":"Salad Add-on"}'

{
    "id": "QZ587JT76N80Y", // modifier group ID
    "name": "Salad Add-in",
    "showByDefault": true
}

In response, a unique modifier group id is generated. By default, the showByDefault value is set to true for prompting merchants to add modifiers in the Clover Register app.

Create a modifier

  1. Send a POST request to /v3/merchants/{mId}/modifier_groups/{modifierGroupId}/modifiers.
  2. Enter required information—modifier name and price.
curl --request POST \
--url 'https://sandbox.dev.clover.com/v3/merchants/{mId}/modifier_groups/{modifierGroupId}/modifiers' \
--header 'content-type: application/json' \
--header 'Authorization: Bearer {access_token}' \
--data '{"price":100,"name":"Tofu"}'

{
    "id":"S47VGYX913K4T" // modifier ID
    "name":"Tofu"
    "price":100
    "modifierGroup":{
    "id":"QZ587JT76N80Y" // modifier group ID
    }
}

In response, a unique modifier id is generated.

Manage items in a modifier group

Associate items with a modifier group

  1. Send a POST request to /v3/merchants/{mId}/item_modifier_groups.
  2. Enter required information—modifier group id and item id.
curl --request POST \
--url 'https://sandbox.dev.clover.com/v3/merchants/{mId}/item_modifier_groups' \
--header 'content-type: application/json' \
--header 'Authorization: Bearer {access_token}' \
--data '{"elements":[{"modifierGroup":{"id":"{modifierGroupId}"},"item":{"id":"{item1Id}"}},{"modifierGroup":{"id":"{modifierGroupId}"},"item":{"id":"{item2Id}"}}]}'

Search modifier groups associated with an item

  1. Send a GET request to /v3/merchants/{mId}/items/{itemId}?expand=modifierGroups.
  2. Enter required information—item id.
curl --request GET \
--url 'https://sandbox.dev.clover.com/v3/merchants/{mId}/items/{itemId}?expand=modifierGroups' \
--header 'content-type: application/json' \
--header 'Authorization: Bearer {access_token}'

{
    "id": "N2WWSQBTAADZC", // item ID
    "hidden": false,
    "name": "Greek Salad",
    ...
    "modifierGroups": { // expansion
        "elements": [
            {
                "id": "QZ587JT76N80Y", 
                "name": "Salad Add-in",
                "showByDefault": true,
                "modifierIds": "S47VGYX913K4T,JRMCKCQK1XCGT",
                "items": {
                    "elements": [
                        {
                            "id": "N2WWSQBTAADZC"
                        }
                    ]
                }
            }
        ]
    },
    "modifiedTime": 1611643817000
}

In response, the modifierGroups expansion displays groups associated with the item. See Expanding fields for more information on working with expand parameters in your requests.

Delete item associations

To delete an association between an item and a modifier group:

  1. Send a POST request to /v3/merchants/{mId}/category_items?delete=true.
  2. Enter required information—category id and item id.
  3. Set the delete value as true.
curl --request POST \
--url 'https://sandbox.dev.clover.com/v3/merchants/{mId}/item_modifier_groups?delete=true' \
--header 'content-type: application/json' \
--header 'Authorization: Bearer {access_token}' \
--data '{"elements":[{"modifierGroup":{"id":"{modifierGroupId}"},"item":{"id":"{itemId}"}}]}'

Search items in a modifier group

  1. Send a GET request to /v3/merchants/{mId}/modifier_groups/{modifierGroupId}/items.
  2. Use filters and expansions to indicate the search parameters.

In the following example, the filter parameter is used to filter by price and the expand parameter is used to provide more information about categories.

curl --request GET \
--url 'https://sandbox.dev.clover.com/v3/merchants/{mId}/modifier_groups/{modifierGroupId}/items?filter=price>=1000&expand=categories' \
--header 'content-type: application/json' \
--header 'Authorization: Bearer {access_token}'

{
    "elements": [
        {
            "id": "N2WWSQBTAADZC", //item matches filter
            "hidden": false,
            "name": "Greek Salad",
            "price": 1200
            ...
            "categories": { // expansion
                "elements": [
                    {
                        "id": "AN7WTGHSKE9XG",
                        "name": "Salads",
                        ...
                    }
                ]
            },
            "modifiedTime": 1611643817000
        }
    ],
    "href": "http://sandbox.dev.clover.com/v3/merchants/{mId}/modifier_groups/{modifierGroupId}/items?filter=price%3E%3D1000&limit=100"
}

In response, items that match the search filters are displayed.

See Apply filters and Use expandable fields for more information on working with filter and expand parameters in your requests. See the API reference for more information about available filters.
