Common questions

Common questions from merchants, developers, and ISOs.

What does "processor-agnostic" mean?

Cloud9 sits between your business and the processor. You integrate once with our API, and we route transactions to any of our 10 supported processors. If you switch processors, your integration stays the same.

What's the difference between full and semi integration?

Semi-integrated gateways hand off terminal communication to a third party. Cloud9 is fully integrated — we control the connection from your POS through the terminal to the processor, giving you faster transactions, better error handling, and one point of support. Learn more

How long does integration take?

Most teams go live in under a week. Our REST API follows the OpenAPI standard with a Swagger sandbox for testing. We also offer an iFrame hosted checkout that requires zero backend work.

Is Cloud9 PCI compliant?

Yes. Cloud9 is PCI-DSS compliant with end-to-end encryption from the terminal to the gateway, and proprietary cross-processor tokenization so card data never touches your servers.

What happens if connectivity drops?

Our proprietary Dual-Factor Store & Forward keeps transactions flowing even when your internet goes down. Transactions are queued locally and settled automatically when connectivity returns.

Which terminals do you support?
