FAQ
Frequently asked questions
Do you store card details?
No. Card data is collected by the provider's secure fields or hosted pages, which keeps most of the PCI scope with them.
Can you integrate our local payment gateway?
Usually yes if it offers a documented API. We assess its reliability, webhooks and settlement reporting first.
Can you help us become a payment service provider?
That is a regulated activity that needs licensing and legal advice. We can build software around it once the model is established.
