Other recommendations
Pre-fill your user’s information
If you have access to your user’s payment information, such as their telephone number, you can pre-fill the relevant field. Your users can still edit the field. Pre-filling avoids extra steps.Use our widget guide to get more information on how to pre-fill the username field.
Keep your current background
When opening the widget, don’t redirect users to a new page as this will create new friction points for your users. Instead, keep them in your app or website and open the widget on top and overlay your current screen.Avoid duplicated UI elements
Avoid repeating navigation elements. Fintoc already includes navigation in the widget, so users can move through the payment flow without duplicate controls.React appropriately when there are errors
Fintoc handles recoverable errors inside the widget. For final-state errors, useerror_reason to explain why the transaction failed and guide your user to retry. See Payment Intent Error Reason for the full list of reasons.
Ask your user to retry with the required changes. Tell them that no money moved because the payment failed.
Close the loop
After a payment succeeds, show what happens next in your website or app. Common use cases include:- P2P transfers: Show a confirmation that the money was sent and update the account balance.
- Fintech wallets or investments: Show the account screen with the new balance.
- E-commerce: Show a confirmation screen with the amount paid, billing details, purchased products, address, delivery date, or next steps.
