SDK Reference
The method, type and error reference for each Tonder SDK.
Tonder's SDKs integrate payment processing directly into your web and mobile applications, with secure data handling and PCI DSS compliance without sensitive data touching your servers.
Integration flow
Your app requests a secure token from your backend to initialize the SDK.
You configure the SDK with customer and cart information.
The SDK renders the payment fields or a full checkout in your app.
The user submits their payment information and the SDK securely sends it to Tonder.
If required, the SDK automatically handles the 3D Secure challenge.
Tonder returns the final transaction status to your app.
