# How Merchandising Works

Each merchandising strategy creates a **ranked list of products** based on rules and algorithms (bestsellers, new arrivals, margin, etc.).

**Key principles**

* Every strategy has a unique **MERCH\_ID**.
* **Scores** are automatically computed and synchronized via API.
* Your **CMS consumes these scores** to reorder products in its catalog.
* **Filters** on your website only hide products — they **don’t change AB Tasty’s ranking**.

**Data flow overview**

1. **Score generation** – AB Tasty calculates a merchandising score per product and strategy.
2. **API sync** – Scores are sent to your CMS or search engine.
3. **Catalog update** – The CMS reorders products using these scores.
4. **Front-end display** – The ordered list is shown on your website; filters simply hide non-matching items.

**Integration logic**\
Your CMS retrieves scores via API:\
`GET https://api.abtasty.com/reco/<MERCH_ID>` → returns product SKUs with their scores.

The CMS then applies these scores as a **sorting layer**. AB Tasty doesn’t recalculate dynamically, ensuring **stable performance**.

**Sync frequency**

* Scheduled (daily/hourly) or manual
