    The package needs to be configured with your account's secret key which is available at

    Require it with the key's value:

    var convertapi = require('convertapi')('your-api-secret');

    Or using ES modules:

    import ConvertAPI from 'convertapi';
    const convertapi = new ConvertAPI('your-api-secret');

    You can specify additional options, like proxy configuration and timeouts, when initializing the client:

    var convertapi = require('convertapi')('your-api-secret', {
      conversionTimeout: 60,
      uploadTimeout: 60,
      downloadTimeout: 60,
      proxy: {
        host: '',
        port: 9000,
        auth: {
          username: 'testuser',
          password: 'secret'

    If using ES module:

    const convertapi = new ConvertAPI('your-api-secret', { conversionTimeout: 60 });
