Transfers

You can move money between internal accounts. Also, you can send and receive funds to and from external accounts.

For more information on transfers, see:

• Internal transfers

  Move funds between internal accounts (Gravv accounts).

• External transfers

• International transfers

  Send funds to bank and Mobile Money accounts in over 50 countries. Recipients receive them in their local currency for cross-border

Get supported transfer currencies

Use the Get supported currencies endpoint to retrieve all fiat currencies available for transfers:

curl --request GET \
     --url https://api.gravv.xyz/v1/transfer/supported-currencies \
     --header 'Api-Key: <Api Key>'

The response returns an array of currency objects, each with a three-letter ISO 4217 code and a human-readable name:

      { "code": "EUR", "name": "Euro" },
      { "code": "GHS", "name": "Ghanaian Cedi" },
      { "code": "KES", "name": "Kenyan Shilling" },
      { "code": "USD", "name": "US Dollar" }
    ]
  },
  "error": null

curl --request GET \
     --url https://api.gravv.xyz/v1/transfer/supported-countries \
     --header 'Api-Key: <Api Key>'

The response returns an array of country objects:

{
  "data": {
    "countries": [
      {
        "currency_code": "NGN",
        "iso3_code": "NGA",
        "iso_code": "NG",
        "name": "Nigeria"
      },
      {
        "currency_code": "KES",
        "iso3_code": "KEN",
        "iso_code": "KE",
        "name": "Kenya"
      },
      {

        "iso3_code": "JPN",
        "iso_code": "JP",
        "name": "Japan"
      }
    ]
  },
  "error": null
}

Each country object contains the following fields:

Field	Description
currency_code	Three-letter ISO 4217 code for the country's local currency. Returns null where a local currency code is not available.
iso3_code	Three-letter ISO 3166-1 alpha-3 country code.
iso_code	Two-letter ISO 3166-1 alpha-2 country code.

Get supported countries for recipient addresses

Use the Get supported countries for address endpoint to retrieve the countries Gravv accepts for recipient addresses in international transfers:

curl --request GET \
     --url https://api.gravv.xyz/v1/transfer/supported-countries-for-address \
     --header 'Api-Key: <Api Key>'

The response returns an array of country objects. Each object includes a two-letter ISO 3166-1 iso_code, the country name, and a states array. Countries without administrative divisions return an empty states array:

{
  "data": {
    "countries": [
      {
        "iso_code": "NG",
        "name": "Nigeria",
        "states": [
          { "code": "NG-LA", "name": "Lagos" },
          { "code": "NG-FC", "name": "Federal Capital Territory" }
        ]
      },
      {
        "iso_code": "JP",
        "name": "Japan",
        "states": []
      }
    ]
  },
  "error": null
}

Use the iso_code and state code values directly in the remitter_address object when building an international transfer request. The static table below lists all countries Gravv currently supports for pay-in and pay-out.
