The best way to start an integration would be by connecting your payment gateways to WhenThen so that you can start getting insights on your current payment transactions. This will allow you to have more visibility on your current payment needs and WhenThen's Insights and Power Ups will help you optimize your payments by recommending payment solutions that will have a significant impact on your payments.
The next step in the integration would be to prepare payment flows in the no-code web app. You can either start with our templates or build your own payment flows from scratch. You can then connect your payment flows directly to your online business. You can also import WhenThen's SDK and integrate directly into your application. It is recommended to do all integrations in a sandbox environment first and to rigorously test.
