Everything You Need to Know
Can I start accepting SumUp payments without changing my current store setup?
Yes. PayLexer integrates SumUp with FluentCart while allowing you to keep your existing store layout, checkout flow, and customer experience.
I've never connected a payment gateway before. Where do I begin?
PayLexer guides you through each step of the setup process, making it easy to connect SumUp without creating your own payment integration or writing code.
If my business grows, can I switch payment gateways later?
Absolutely. If your payment requirements change, you can connect another supported payment gateway through PayLexer without rebuilding your FluentCart store.
What happens inside my store after a customer completes payment?
After SumUp confirms the transaction, PayLexer notifies FluentCart so your store can continue processing the order through its normal workflow.
Will I need to start over if I update my SumUp account?
No. If your integration settings change, simply update them in PayLexer. Your store remains connected, so there’s no need to repeat the entire setup.
Does PayLexer process my payments?
No. Payments are processed securely by SumUp. PayLexer simply acts as the connection between your FluentCart store and the payment gateway.
What if something isn't working the way I expected?
Don’t worry, you don’t have to figure it out on your own. The PayLexer support team is available to help with setup questions, troubleshooting, or anything else related to your integration.
