Live Testing and Launch

Pre-Launch Testing

After completing the integration, we recommend you test and validate your product to ensure it works as expected.

Testing Requirements:

• Real bank accounts and individuals with local authorization methods (BankID, MitID, etc.)
• End-to-end live tests with at least 3 different bank groups in your target country
• Complete payment flows from initiation to completion

Launch Coordination

Before going live:

1. Complete comprehensive testing across multiple bank groups
2. Schedule a sync with your Neonomics Customer Success team contact
3. Review the complete flow together
4. Notify the team of your planned launch date

Mobile App Implementation

💡

Best Practice: For the optimal user experience in mobile apps, redirect users to a dedicated browser rather than using an in-app browser.
