# Connect your systems to Nasam’s marketplace platform.

**Nasam MM-API (Marketplace Management API)** gives partners access to brands and their connected marketplace accounts. Discover the brand and account IDs, then use the API to work with catalog, inventory, orders, fulfillment, and reporting.

## Your first request

List the brands available to your organization. Use a returned brand ID to scope later calls.

```
curl --get 'https://backend.nasam.co/v1/brands' \
  -H 'accept: application/json' \
  -H 'key: YOUR_API_KEY'
```

## From API key to marketplace data

Request a key, find an accessible brand, and use its ID to read connected accounts and products.

1.  ### Request an API key
    
    [Contact Nasam sales](https://nasam.co/#contact) for access. Send your key from your server in the `key` header. See [authentication and scope](/docs/authentication).
    
2.  ### Find a brand and account
    
    [List accessible brands](/docs/reference/get-all-brands-v-1-brands), then read the selected brand’s [connected sale-channel accounts](/docs/reference/get-sale-channel-status-v-1-brands-brand-id-sale-channels). Keep the brand, channel, and account IDs distinct.
    
3.  ### Read a brand’s catalog
    
    Use the returned brand ID in a [products request](/docs/reference/get-products-v-1-products). Check the operation’s filters, response, and required grant before building a scheduled sync.
    

**Brand, channel, and account IDs**

A brand is the business scope. A sale channel identifies a marketplace and region. A sale-channel account is the brand’s connection to that channel. Use the IDs returned by the API in later requests.
