## How IteraPay works

IteraPay organizes everything around **merchants** — each merchant account holds balances across supported crypto tokens. Within a merchant, you create **invoices** that generate unique blockchain deposit addresses for customers, track **transactions** as payments arrive, **collect** settled funds into your main balance, and **withdraw** to any on-chain address.

<Steps>
  <Step title="Create a merchant">
    Set up a merchant account to hold your payment settings and balances.
  </Step>

  <Step title="Generate an API key">
    Authenticate your integration with a scoped API key for your merchant.
  </Step>

  <Step title="Create an invoice">
    Generate a one-time or reusable payment invoice and share the payment address with your customer.
  </Step>

  <Step title="Collect & withdraw">
    Once payments arrive, collect settled funds and withdraw to your destination address.
  </Step>
</Steps>
