<Accordion title="Including purpose of payment">
For external account or UMA destinations, some payment corridors require a purpose of payment. Include it in the `senderCustomerInfo` object:

```json
{
"source": { "accountId": "InternalAccount:..." },
"destination": { "accountId": "ExternalAccount:...", "currency": "EUR" },
"lockedCurrencySide": "SENDING",
"lockedCurrencyAmount": 10000,
"senderCustomerInfo": {
"PURPOSE_OF_PAYMENT": "GOODS_OR_SERVICES"
}
}
```

**Purpose of payment codes:**
- `GIFT` - Personal gift
- `SELF` - Transfer to yourself
- `GOODS_OR_SERVICES` - Payment for goods or services
- `EDUCATION` - Education-related expenses
- `HEALTH_OR_MEDICAL` - Medical or healthcare expenses
- `REAL_ESTATE_PURCHASE` - Real estate transaction
- `TAX_PAYMENT` - Tax payment
- `LOAN_PAYMENT` - Loan repayment
- `UTILITY_BILL` - Utility bill payment
- `DONATION` - Charitable donation
