[Contact us](https://hyperdc.com/contact-us) Chat with our team ### Which modules are there? A WHMCS module (WHMCS 8 and 9) with an addon for your catalogue and prices and a registrar module for domains; a Blesta module that does the same on the module’s page; a HostBill hosting module with a Server widget and a domain module; a WISECP product module with its own management page and a registrar module. Each comes with a detailed guide. Any other billing system can use the API directly. ### Where do I get my API key? On the Reseller page of your client area, once your reseller account is active. Each key works only from the IP addresses you give it, and its secret is shown once. ### How is a request signed? Every request carries your key ID, a timestamp, a one-time nonce and an HMAC-SHA256 signature of the method, the path, the timestamp, the nonce and the body’s hash. The modules do this for you; the API guide shows it step by step. ### What if an order request is sent twice? Nothing is ordered twice. Each order carries your own reference, and the same reference answers with the service it already created. ### How many requests can I send? Up to 120 requests a minute for each key, which covers ordering and managing many servers at once. ### Where are the full guides? On the Reseller page of your client area, with the modules to download: the API guide and one guide for each module. ## Questions before you order?
