Retrieve Bloomreach Discovery product recommendations using the Recommendations and Pathways API v2

Steps

1. Identify the widget type and widget_id you want to call; widget IDs are configured in the Bloomreach dashboard for each recommendation strategy (e.g., 'recently viewed', 'similar products', 'top sellers').
2. Send a GET request to the production endpoint: https://pathways.dxpapi.com/api/v2/widgets/{widget_type}/{widget_id}?account_id=YOUR_ACCOUNT&domain_key=YOUR_DOMAIN&_br_uid_2=USER_COOKIE.
3. Pass the auth-key as a request header (Authorization: YOUR_AUTH_KEY) for the v2 API; unlike v1, the v2 API does not accept the auth key as a query parameter.
4. Include item_ids (comma-separated product IDs) for item-context widgets like 'similar items' or 'bought together'; include user_id and _br_uid_2 for user-context widgets like 'personalized recommendations'.
5. Parse the response JSON; results are in the response.docs array. Cache responses per user/product at the edge according to the Bloomreach caching guide to reduce latency and API load.
