# Purpose codes

> Purpose codes required by destination country.

Every international wire request must include a non-empty
`internationalWire.purposeCode`. It describes the economic purpose of the
payment.

Use the code supplied by the beneficiary or required by their receiving bank.
For example:

```json theme={null}
{
  "internationalWire": {
    "purposeCode": "GDDS",
    "remittanceInfo": "Invoice 1042"
  }
}
```

Purpose-code requirements vary by corridor. Use the beneficiary bank country's
enumerated list when one is available; otherwise use a general ISO 20022 code
or the formatted value required by the receiving bank.

Browse [Purpose code values](/docs/v2/money-movement/international-wires/purpose-code-values)
for every code currently exposed by Slash. A receiving institution may still
reject a code that does not fit the payment.

Some destination countries also require
`internationalWire.remittanceInfo`. When it is required, describe the
payment clearly enough for the receiving institution to apply it.
