# Onramp: Overview

Coinbase Onramp allows your users to convert fiat currency into crypto and send it to any wallet. Users can onramp by logging in with their Coinbase account or using Guest Checkout with a debit card, Apple Pay, or Google Pay (no Coinbase account required).

<Tip>

## How it works

Whether you choose Coinbase-hosted or Headless Onramp, the basic flow is the same:

```mermaid theme={null}
sequenceDiagram
    participant User
    participant YourBackend as Your Backend
    participant TokenAPI as Token API
    participant Coinbase as Coinbase Onramp
    participant Wallet as User's Wallet

    User->>YourBackend: Request to buy crypto
    YourBackend->>TokenAPI: Create session token<br/>(with wallet address)
    TokenAPI-->>YourBackend: Return token
    YourBackend-->>User: Redirect to Onramp URL<br/>(with token)
    User->>Coinbase: Complete purchase<br/>(pay with card/bank)
    Coinbase->>Wallet: Send crypto to destination
    Coinbase-->>User: Purchase complete
```

<Warning>
  **Important:** Session tokens are single-use and expire after 5 minutes. You must create a new token for each user session.
</Warning>
