# Retail Master Data

> Purchases, stores, products, hierarchies and articles.

Retail Master Data covers the retailer's own world — what you sell, where you sell it, and what was sold. The **Purchase API** here is the endpoint that records a finalized transaction and triggers bonus, receipts and challenge progress.

<Warning>
  `POST /v1/purchases` is the only call that records a sale. Discount calculation and payment capture do not.
</Warning>
