On this page, the [integration checklist](#integration-checklist) that you should use depends on the product data model you employ. For more information, refer to the: * [Defining goods and services page](/digital-river-api/product-management/skus.md) * [Sending product data in the checkouts](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md#sending-product-data) section on the [Describing line items](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md) page ## Integration checklists The integration checklist you should work from in this section depends on your [product data model](/digital-river-api/product-management/skus.md). {% hint style="info" %} For more information, refer to the [sending product data in checkouts](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md#sending-product-data) section on the [Describing line items](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md) page. {% endhint %} Click any checklist item for more details on meeting the integration standard. ### SKUs only checklist * [ ] [Do you have a method for manually synchronizing a full product catalog using the SKUs API?](#manually-synchronize-your-catalog) * [ ] [Do you have a scheduled job or real-time trigger to synchronize new and updated products in your catalog with their corresponding SKUs in our system?](#automatically-synchronize-your-catalog) * [ ] [Can you capture a product's tax code, ECCN, and country of origin within your product admin interface?](#capture-sku-attributes) * [ ] [Does your integration use your source system's unique product identifier as the SKU identifier when interfacing with the SKUs API?](#ensure-product-and-sku-identifiers-match) ### SKUs with SKU groups checklist * [ ] [Do you have a method for manually synchronizing a full product catalog using the SKUs API?](#manually-synchronize-your-catalog) * [ ] [Do you have a scheduled job or real-time trigger to synchronize new and updated products in your catalog with their corresponding SKUs in our system?](#automatically-synchronize-your-catalog) * [ ] [Does your integration use your source system's unique product identifier (UUID) as the SKU identifier when interfacing with the SKUs API?](#ensure-product-and-sku-identifiers-match) * [ ] [Have you associated a SKU group with each of your SKU's?](#associate-a-sku-group-with-each-sku) ### Product details with SKU groups checklist * [ ] [Have you associated a SKU group with each product in your system?](#associate-a-sku-group-with-each-product-in-your-system) ## Integration standards The product and SKU standards that apply to your integration depend on which of the above :point\_up: checklists you're using. ### Manually synchronize your catalog You should have a tool that manually imports and then allows you to periodically update your products in Digital River's system through the [SKUs API](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/skus). Your platform's admin interface most likely already has a product management page. You can simply modify this page to perform [SKU imports and updates](/digital-river-api/product-management/creating-and-updating-skus.md#creating-and-updating-a-sku). ### Automatically synchronize your catalog Product catalogs are often very large. To optimize performance, you should synch your products and SKUs on a timed schedule or using a similar trigger. These scheduled jobs should make as few calls to the [SKUs API](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/skus) as possible. Therefore, we suggest you use a delta to only update the attributes in a SKU that changed in its corresponding product. This prevents you from having to overwrite every SKU value each time you run a synchronization job. ### Capture SKU attributes If you're [sending product data in checkouts](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md#sending-product-data) by referencing SKUs that don't belong to [SKU groups](/digital-river-api/product-management/setting-up-sku-groups.md), then you should add the following attributes to the product schema in your commerce platform: * [Export Control Classification Number](/digital-river-api/product-management/creating-and-updating-skus.md#eccn) * [Country of origin](/digital-river-api/product-management/creating-and-updating-skus.md#country-of-origin) * [Tax code](/digital-river-api/product-management/creating-and-updating-skus.md#tax-code) Similarly, regardless of whether or not you associate SKU groups with SKUs, if you're [sending product data in checkouts](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md#sending-product-data) by referencing SKUs, you should also add the following attributes to your platform's product schema: * [Part number](/digital-river-api/product-management/creating-and-updating-skus.md#manufacturer-id-and-part-number) * [Weight and weight unit](/digital-river-api/product-management/creating-and-updating-skus.md#weight-and-weight-unit) * [Image and URL](/digital-river-api/product-management/creating-and-updating-skus.md#image-and-url) * [Fulfillment coordinator](/digital-river-api/product-management/creating-and-updating-skus.md#managed-fulfillments) When you set these values in your admin interface, you can [sync your products with their corresponding SKUs](#automatically-synchronize-your-catalog) in Digital River's system. ### Ensure product and SKU identifiers match Your product's identifier should match the [identifier of its corresponding SKU](/digital-river-api/product-management/creating-and-updating-skus.md#unique-identifier) in our system. It's important that these values are the same. This ensures that synchronization is possible and that the SKUs work properly during [checkouts](/digital-river-api/integration-options/checkouts/creating-checkouts.md). ### Associate a SKU group with each SKU Before deployment, you should [associate a SKU group with each of your SKUs in our system](/digital-river-api/product-management/setting-up-sku-groups.md#using-sku-groups-in-transactions). ### Associate a SKU group with each product in your system Before deployment, you should [associate a SKU group with each product in your system](/digital-river-api/product-management/setting-up-sku-groups.md#using-sku-groups-in-transactions). ## API interfaces | Documentation | Direct API | PHP SDK | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------- | | [Defining goods and services](/digital-river-api/product-management/skus.md), [Grouping SKUs](/digital-river-api/product-management/setting-up-sku-groups.md), [Sending product data](/digital-river-api/integration-options/checkouts/creating-checkouts/describing-the-items.md#sending-product-data) | [SKUs](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/skus) | [SKUs](https://github.com/DigitalRiver/digital-river-php/blob/main/docs/Model/Sku.md) |
