# Nymble Commerce: B2B Commerce API for Modern Buying Experiences

> Nymble Commerce is a multi-tenant B2B commerce API. Manage catalogs, customers, orders, invoices, payments, and integrations through one secure API.

Nymble Commerce gives product companies, distributors, and manufacturers a single, secure API to power their digital B2B buying experiences — from product catalogs and contract pricing to carts, orders, invoices, and payments. Everything is organization-isolated by default, so you can serve multiple brands or customer segments without data leakage.

## How it works

<Steps>
  <Step title="Authenticate">
    Obtain an access token by exchanging your organization credentials at `/api/auth/login`, or pass a pre-issued API key in the `x-api-key` header for machine-to-machine workflows.
  </Step>

  <Step title="Set up your catalog">
    Create products with pricing tiers, attach images, and organize everything into categories. Nymble Commerce resolves the right price for each customer automatically.
  </Step>

  <Step title="Take orders">
    Build a cart, add line items, apply shipping details, and complete checkout in a single API call. Orders flow automatically into invoicing.
  </Step>

  <Step title="Get paid">
    Collect payments through hosted payment pages or saved payment methods. Record payments against invoices and issue refunds when needed.
  </Step>
