WHMCS' API Node client.

Install Node.js version 12.0.0 or higher.

npm install whmcs

First you need to instantiate it.

You can instantiate with api credentials:

const config = {
  apiIdentifier: '<your_api_identifier>',
  apiSecret: '<your_api_secret>',
  accesskey: '<your_access_key>', //optional. use it to bypass IP restrictions
  serverUrl: 'https://127.0.0.1',
  userAgent: '<your_user_agent>'
};

const wclient = new WHMCS(config);

Or you can instantiate with administrator username and password:

const config = {
  username: process.env.WHMCS_USER || '<your_admin_username>',
  password: process.env.WHMCS_PASSWORD || '<your_password>',
  accesskey: '<your_access_key>', //optional. use it to bypass IP restrictions
  serverUrl: 'https://127.0.0.1',
  userAgent: '<your_user_agent>'
};

const whmcs = new WHMCS(config);

With the created WHMCS client, you should get the category/module you want (see available modules) and call the method you need.

For example, you can fetch 10 users like this:

const parameters = {
  limitstart: 0,
  limitnum: 10
};
  
whmcs.users.getUsers(parameters)
  .then(details => {
    ...
  })
  .catch(err => {
    ...
  });

If you want/need to, you can use callbacks instead:

const parameters = {
  limitstart: 0,
  limitnum: 10
};
  
whmcs.users.getUsers(parameters, function (err, details) {
  ...
});

This node-js module follows WHMCS' API Index structure, which have functions organized by categories. Every category is represented here by a module Object, and each module has public methods representing WHMCS' functions.
When WHMCS' function requires parameters, they must be grouped in a JSON Object and then can be set as the first argument of the method. If no parameters are required, this argument must not be set. The "callback" argument is optional, and when not provided the method returns a Promise. This pattern is shared all across the modules public methods.

The WHMCS' API Index can be updated anytime, so you must check below which functions are implemented (expand to show the function list).

It is possible to call custom functions using the method callApi:

const parameters = {
  paramx: 'x',
  paramy: 'y'
};

whmcs.callApi('CustomFunctionName', parameters)
  .then(details => {
    ...
  })
  .catch(err => {
    ...
  });

Tests are implemented using mocha and chai. Run them with npm test.
