        "connector": "lb-connector-mandrill",
        "apikey": "[your api key here]"
    }

        "connector": "lb-connector-mandrill",
        "apikey": "[your api key here]",
        "defaults": {

var dsMandrill = new DataSource('lb-connector-mandrill', {

});

3. Use

Basic option same as built in Loopback

loopback.Email.send({
    to: "test@to.com",
    from: "test@from.com",
    subject: "subject",
    text: "text message",
    html: "html <b>message</b>"
},
function(err, result) {
    if(err) {
        console.log('Upppss something crash');
        return;
    }
    console.log(result);
});

Some advantages - now you can use templates from Mandrill

loopback.Email.send({
    to: "test@to.com",
    from: "test@from.com",
    subject: "subject",
    template: {
        name: "signup-confirm",
        content: {
            name: "NewUser Name",
            accountId: "123456"
        }
    }
},
function(err, result) {
    if(err) {
        console.log('Upppss something crash');
        return;
    }
    console.log(result);
});

To customize emails using merge_vars

Single Recipient

var
  params,
  user = {
    firstName: 'Paul',
    email: 'paul@example.com'
  }
  
  params = {
    to: user.email,
    template: {
      name: 'test-email',
      merge_vars: [ 
        //in your mandrill template `*|FIRST_NAME|*`
        {
          name: 'FIRST_NAME',
          content: user.firstName
        }
      ],
      global_merge_vars: [
        //in your mandrill template `*|team|*` or `*|TEAM|*`
        {
          name: 'TEAM',
          content: 'Team Awesome'
        }
      ]
    }
  };
  
  loopback.Email.send( params, function( err, email ) {
      ...
  })

Multiple Recipients

var
  params,
  users = [
    {
      firstName: 'Kaitlin',
      email: 'kaitlin@example.com'
    },
    {
      firstName: 'Ryan',
      email: 'ryan@example.com'
    }
  ];

params = {
  to: users.map( function( user ) {
    return user.email;
  }),   
  template: {
    name: 'test-email',
    merge_vars: [
      // in your mandrill template `*|FIRST_NAME|*`
      // content is a callback the recieves email and index
      // and returns the value for that merge_var for that user
      {
        name: 'FIRST_NAME',
        content: function( email, index ) {
            return users[ index ].firstName;
        }
      }
    ]
  }
};

loopback.Email.send( params, function( err, email ) {
    ...
})
