WRA (WHMCS Restful API) is an addon for expose a RESTful API in WHMCS. Using the native API of WHMCS we expose a new end-point inside your WHMCS installation, for use a most simple API interface. This new interface of API (WRA), is documented in swagger and has a client library ready to use. For maintaining the project we use a licenze system: free for small implementation minimal cost of licenze for medium and big implementation
For installing the WRA just unzip it in the main WHMCS folder. Go in the folder: /modules/addons/wra/api/ and rename the file htaccess.txt to: .htaccess After installation of files, go in Setup>Addon modules and click "Activate" button on the "WHMCS RESTful Api" addon. Now click "Configure" button and you can see in you licenze and licenze token.
