Let customers exchange currencies inside your app, with the rate source, markup and fees you set in the Back-Office Dashboard.
Choose rate sources, configure your pricing and set the workflow for customer exchange requests.
Help customers hold, convert and use different currencies within a familiar banking experience. Make the quote and the amount they receive clear before they exchange.
Use supported FX providers or reference-rate sources for your currency pairs. Keep the rate source distinct from the provider used to execute an exchange, and apply your pricing rules to the customer quote. Support current rates and rate history through the currency APIs.
Configure an included FX markup or a separately charged exchange fee. Use an exchange preview to check what the customer sends, receives and pays before the order is confirmed.
Use exchange orders to coordinate commissions and execution through liquidity providers. For OTC or brokerage-style products, configure an exchange-request workflow and the back-office review your team needs.
Choose integrations that fit your programme, market and required capabilities.
Request an exchange rate for a currency pair and amount before your customer moves ahead. Connect your conversion screen to the rates available in your environment.
