How It Works
Integrate the PaySec gateway in four steps.
Get API Keys
Sign up for a merchant account and receive your sandbox and production API keys. Full documentation and code samples are available in the developer portal.
Integrate
Use our SDKs for Node.js, Python, PHP, Ruby, or .NET — or call the REST API directly. Hosted checkout is available for teams that want a no-code option.
Test in Sandbox
Process test transactions with simulated card numbers. Test success, decline, and error scenarios. Verify webhook delivery and response handling.
Go Live
Swap sandbox keys for production keys and start processing real transactions. Your dedicated account manager is available for launch support.

“We migrated from Stripe in a weekend. The API is clean, the SDKs are well-documented, and $0 processing fees save us $4,000 a month at our volume. Our engineering team was genuinely impressed.”
