This guide describes how to create and retrieve discounts by using the Discounts GraphQL API. It provides examples for two different types of discounts (automatic discounts and code discounts), and the recommended best practices for each type.
All of the queries and mutations in this guide are for the unstable API version. You can access them by making your calls to https://.myshopify.com/admin/api/unstable/graphql.json. For a full list of the schema, see the GraphQL Admin API reference.
The mutations described here require the write_discounts permission.
The queries described here require the read_discounts permission.
Creating automatic discounts
Automatic discounts refer to the set of objects and mutations in GraphQL that let you create and manage discounts that are automatically applied to a cart if prerequisites are met. This method is available only in the GraphQL Admin API.
The following examples show two different types of automatic discounts:
This example shows how to create an automatic Buy One Get One discount that will be applied to a single product any time it’s included in a cart. In this case, it applies a 100% discount on the second item in a cart, as long as it’s the same product as the first item.
Based on that example, you can make a few different changes to offer specific types of discounts:
If you want to change the discount amount, then edit customerGets.value.discountOnQuantity.effect.percentage.
If you want to apply the discount to a different item, then use customerGets.items.products.productsToAdd and customerGets.items.products.productsToRemove to update the entitlements.
If you want to apply the discount to all items, then use customerGets.items.all instead of a specific product ID.
If you want a customer to get a discount no matter which item they purchase, then set the customerBuys.items.all prerequisite to true instead of a specific product.
Percentage or fixed-amount automatic discount
This example shows how to create an automatic discount of 10% that will be applied to a single product any time it’s included in a cart. The percentage input requires a value between 0 and 1. In the example below 0.10 represents 10% off. A 100% discount would be 1.0 and a 50% discount would be 0.5.
Creating code discounts
Code discounts refer to the set of objects and mutations in GraphQL that let you create and manage discounts that include a unique code. Code discounts enable specific discounts to be redeemed when the codes are applied manually by the customer during the checkout. This method is available only in the GraphQL Admin API.
The following examples show three different types of code discounts:
This example shows how to create a Buy One Get One discount that requires the customer to enter a code at checkout. In this case, it lets all customers use this code, and offers a buy one get one discount on the same product. You can also change the discount so that it applies to a different product than the original.
Percentage or fixed-amount discount code
This example shows how to associate a flat percentage or fixed-amount discount with a code that the customer can use at checkout. Similar in format to creating a buy one get one discount, here we will create a $1.00 off discount for a specific product.
Free Shipping code discount
This example shows how to associate a Free Shipping discount with a code that will grant the customer free shipping when they use it. In this example, the discount applies to a saved search of customers in customerSelection.customerSavedSearches if those customers are from Canada. If you want to provide the discount to all countries, then you can replace destination.countires.add with destination.all set to true. Note that if you specify a country where you want to offer free shipping, the shop must have a shipping zone configured for that country before it will work.
You can use the API to manage and make changes to your current discounts.
Query automatic discounts on a shop
When making GraphQL queries, you can return multiple objects at a time. The following example shows how to request the first 10 automatic discount codes, which returns the details about whether they’re either the BxGy or Basic type.
Query a specific automatic discount
To query a specific automatic discount, all you need is its ID. The following example query might look complicated because it uses a concept called fragments. This lets you create a query that returns the information only if it matches your criteria. In this case, we are requesting all possible information about this discount no matter what type it is, in case we don’t know the details of the automatic discount beforehand.
Activate and deactivate automatic discounts
To activate or deactivate an automatic discount, you can use the mutations discountAutomaticActivate or discountAutomaticDeactivate. The only input required is the ID of the automatic discount to perform the action on.
Query code discounts on a shop
The following example shows how to query basic code discounts on a shop. As with all GraphQL queries, you can request only the details that you want in the query to keep it short. We’ll expand on all possible fields here in the next examples so no need to include them all twice.
Query a specific discount code
Similar to automatic discounts, you can query a specific code by ID and request only the information you want. Here is an example of all possible fields on a basic discount code. In the following example, you could replace the DiscountCodeBasic fragment with DiscountCodeBxgy or DiscountCodeFreeShipping. Although they all have a slight variation in the return fields, the basic format is the same.
Update an automatic discount
Updating a discount is done in the same way as creating a discount, but it has a unique mutation. Use discountAutomaticBxgyUpdate if it’s a BxGy discount, or discountAutomaticBasicUpdate if it’s a basic discount. Note that when updating a discount code, you have to explicitly add and remove entitled products by using productsToAdd and productsToRemove as shown in the example below. You can add or remove multiple products by passing them in a comma-separated list.
Update a code discount
Updating a discount is done in the same way as creating a discount, but it has a unique mutation. Use discountCodeBxgyUpdate if it’s a BxGy discount, discountCodeBasicUpdate if it's a basic discount, or discountCodeFreeShippingUpdate if it’s a Free Shipping discount. If you want to update a discount, then you need to pass in the ID of the code that you want to update. Also note that you only need to include the fields that you want to update (in the following example, only the title is included).
Delete an automatic discount
To delete an automatic discount, all you need is its ID.
Bulk delete automatic discount
The following example shows how to delete automatic discount codes in bulk by specifying an array of IDs.
Paginate through discount codes
If you aren't familiar with pagination through GraphQL, then see the Shopify GraphQL Learning Kit. The way that the pageInfo and cursor parameters are structured in the discounts object is similar to how they're structured elsewhere in GraphQL. The following example shows a sample query with these parameters.
