Search for a product in RetailCRM

To search for products in the RetailCRM API use the storeProducts method, which takes three parameters:

1. Filter — required array of product data (ID, price, vendor, product groups, tags, segments, etc.)
2. page — page number for pagination. If there are many results (at most 20 per request), use this to request further pages.
3. limit — number of products returned per request (max 20).

Search by site product ID (externalId)

$products = $modRetailCrm->request->storeProducts(array('externalId' => 100), 1, 20);
