# API Store overview

> Accept card, Papara, bank transfer, and crypto payments from your own site.

The API Store lets any website or bot take payments through PapelShip. Pick the flow that fits your checkout.

<CardGroup cols={2}>
  <Card title="Hosted payment links" icon="link">
    PapelShip hosts the checkout. Your customer picks a method: credit card, Papara, bank transfer, or crypto.
  </Card>

  <Card title="Direct crypto invoices" icon="bitcoin-sign" href="/en/api-store/crypto-payments">
    You build the checkout. PapelShip gives you a unique deposit address, the exact crypto amount, and a QR code.
  </Card>
</CardGroup>

## Payment lifecycle

  A[Create invoice] --> B[Customer pays]
  B --> C[Blockchain / gateway confirms]
  C --> D[Check status]
  D --> E[Fulfill order]
```

1. Create an invoice with [payment links](/en/quickstart) or a [crypto invoice](/en/api-store/crypto-payments).
2. The customer pays on the hosted checkout or to the deposit address.
3. Poll the [status endpoint](/en/api-store/crypto-payments#track-confirmations) until `is_paid` is `true`.
4. Fulfill the order. Issue [refunds](/en/api-store/overview#refunds) when needed.
