Integrations

Works with any REST API. No integration required.

Stripe, AWS, your internal microservices, or the SaaS tool you found yesterday — if it has an HTTP endpoint, KnoxCall proxies it, injects the credentials at the wire, and audits every call. The APIs below are just the ones our customers protect most.

Your API isn't listed? Perfect.

We don't keep an integrations list to maintain — KnoxCall proxies any HTTP request to any endpoint. Internal APIs, legacy SOAP services, the startup tool with three customers: all secured the same way.

Tomorrow you could be securing an API that doesn't exist today. That's the whole point.
