Crypto ramp providers

Crypto ramp providers facilitate the conversion from fiat currencies (e.g. USD) to non-fiat currencies (e.g. cryptocurrency), or vice versa. Card networks require ramp provider merchants to include special transaction indicators in their authorization requests to identify the type of ramp transaction. Merchants who have contracted third-party conversion affiliates for conversion services must also submit relevant affiliate data in their authorization request.

How to enable

Use the merchant.rampProvider object to identify your ramp provider and, where applicable, include conversion affiliate details.

Special transaction indicator

From October 2024, Visa introduced a mandate to include special transaction indicators to increase transparency and clarify dispute rules for digital currency and NFT transactions. Send the relevant purpose value inside instruction.fundsTransfer:

{
  "instruction": {
    "fundsTransfer": {
      "type": "purchase",
      "purpose": "stablecoin"
    }
  }
}

Supported purpose values:

blockchainNativeToken
crypto
stablecoin
nft
cbdc

You must always send the above purpose values with fundsTransfer.type of purchase or walletLoad. Sending any other type may lead to increased decline rates from card networks.

Ramp provider reference

Card networks mandate that crypto ramp merchants submit their unique identifier in every authorization:

{
  "merchant": {
    "rampProvider": {
      "reference": "12345677898"
    }
  }
}

You can't send rampProvider data together with paymentFacilitator data.

Conversion affiliate data

If the ramp provider uses conversion affiliates, submit the affiliate details inside merchant.rampProvider:

{
  "merchant": {
    "rampProvider": {
      "reference": "12345677898",
      "conversionAffiliate": {
        "reference": "1234567890",
        "name": "Name",
        "url": "http://some-url-here.com",
        "taxReference": "987-654-4321",
        "address": {
          "countryCode": "US"
        }
      }
    }
  }
}
