## At a glance

- **Where**: Wherever CoinGate onboards merchants. CoinGate is custodial and verifies your identity.
- **Currencies**: The fiat currencies you list on the connection. CoinGate prices in fiat.
- **Confirmation**: Automatic. The processor tells Sellstamp, and the order is paid and delivered with no action from you.
- **Refunds**: Not through Sellstamp. Return the money yourself, then record the refund on the order.
- **Subscriptions**: No. One-off purchases only.

## What you need

- An API key (sandbox and live keys are separate)

## Connecting it

1. Paste the API key into Payments → CoinGate, list your price currencies, then run the connection test.

## Worth knowing

- CoinGate's API has no refund endpoint. Refund from CoinGate's own dashboard and record it on the order.
