# Gateway Routing

> How Khaime selects the optimal payment gateway.

# Gateway Routing

Khaime automatically routes each payment to the best gateway based on the customer's currency and region. You don't need to configure or select gateways — it's handled for you.

## How It Works

1. You send a [charge request](/api-reference/payments/create-charge) with the customer's currency
2. Khaime selects the optimal gateway for that currency and region
3. The response tells you which checkout flow to use

## Checkout Flows

The charge response includes a `payment_gateway` field. Your integration needs to handle two checkout types:

| Flow         | When                        | What to do                                                                     |
| ------------ | --------------------------- | ------------------------------------------------------------------------------ |
| **Embedded** | `client_secret` is returned | Mount a payment element on your page using `client_secret` + `publishable_key` |
| **Redirect** | `payment_url` is returned   | Redirect the customer to the hosted payment page                               |

## Example Response

```json theme={null}
// Embedded flow
{
  "payment_gateway": "...",
  "client_secret": "pi_xxx_secret_xxx",
  "publishable_key": "pk_xxx",
  "charge_id": "charge_xxx"
}

// Redirect flow
{
  "payment_gateway": "...",
  "payment_url": "https://...",
  "charge_id": "charge_xxx"
}
```
