HTML Integration: Add to Registry Page (Legacy)

NOTE This section refers to a legacy feature which is only available to existing customers. New and existing customers looking to add personalization should refer to Add to Registry Page (JSON)

The add to registry page is displayed immediately after a shopper adds a product to their registry or wish list. It is a distinct page separate from the registry page, typically offering other products, options, or information relevant to the product just added to the registry. It may be a modal window or an interstitial page.

How To Make This Code Work For You

Follow the sample integration code below, making these changes:

Function Requirement
R3_COMMON.setApiKey('MY_API_KEY'); Replace MY_API_KEY with your site’s API key, a unique identifier for your account.

Set RRSERVER_URL to one of these values.

For initial development:


For production:


R3_COMMON.setSessionId('USER_SESSION_ID'); Replace USER_SESSION_ID with the session ID for the current user and session. The session ID is a crucial variable that allows Algonomy to track shopper behavior when they visit your site so recommendations can be generated. This parameter should remain the same from start to finish for a user’s shopping session.

Replace USER_ID with the user ID, a unique string to identify each user. All user behavior will be stored using this key. It is case-sensitive and should be the same UserId sent to {rr} in other applications.User IDs are often connected to email addresses, and can be directly linked to the login credentials a consumer uses to log into and buy products from the e-commerce site. To avoid sending personally identifiable information to Algonomy, you can use a hash of your site’s user ID (if, for example, your site uses email addresses as user IDs, then you should not send that information directly to Algonomy).

Note: if the USER_ID is unknown, leave it blank.

R3_ADDTOREGISTRY.addItemIdCentsQuantity('ITEM_ID', 'PRICE', 'QTY', 'SKU'); Replace ITEM_ID with the item ID, a unique identifier for the item.Replace PRICE with the price of a single item in decimal format, ex. 19.99. Replace QTY with the quantity for this product.Replace SKU with the specific SKU the user has purchased. If there is no SKU ID, this can be left empty.​

No changes are required.

This code enables the client to send the domain for click-through URL through the p13n_generated.js call if relative URLs are supplied in the feed. For example, if the domain calling our code is or, we can automatically redirect to the correct domain.
