Build against contracts, not guesswork.

OpenAPI contracts per service, isolated sandbox keys, signed webhooks and idempotent money movement.

A real transfer contract.

  "amount": 250000,
  "currency": "NGN",
  "sourceWalletId": "wallet_id",
  "destinationWalletId": "wallet_id",
  "reference": "your_unique_reference"
}

Examples are provided for cURL, Node.js, Python and Java. They are not downloadable SDKs.
