Wallet-to-Wallet Transfers
You can allow a Nium onboarded customer to transfer funds from their wallet to another Nium onboarded customer with a suite of Nium One platform fund transfer APIs, which your customer has authorized to do so.
The sender and the receiver of the funds can be an individual or a business and can belong to the same or a different client setup based on geographic regions. Global clients have multiple client setups on the platform where customers across the client setups require wallet-to-wallet transfers.
IMPORTANT
To enable wallet-to-wallet fund transfers across multiple client setups, contact your Nium representative.

Wallet-to-Wallet Transfer API
The Wallet-to-Wallet Transfer API allows you to transfer funds in the same currency. For example, the source and the destination currency are the same for the sender and the receiver.
The operation also lets you transfer funds between different currencies.
- The sender can use the Create Conversion API to send money from one currency to another in the same wallet. The sender then uses the Wallet to Wallet Transfer API to send the converted currency to the receiver’s wallet.
- The sender can use the Wallet-to-Wallet Transfer API to transfer funds to the receiver’s wallet. The receiver then uses the Create Conversion API to transfer funds from one currency to the desired currency in the same wallet.
