Programatically adding and removing products to Downpay purchase options

Using the Downpay API, you can add or remove products to purchase options with a single API call. For inputs, you will need:

• The id of the purchase option in the app. You can find this ID by editing the relevant purchase option in the app - it is the last part of the URL of the edit page
• The ids of the Shopify product(s) you'd like to add to the option.

The API is in GraphQL.

      message
    }
    purchaseOptionGroupId
  }
}
