Need some help importing NPM - beginner

So, here’s my “playground” for trying to accomplish my goal of being able to call meteor methods from within particle-api-js getEventStream() using 1.2…

if (Meteor.isServer) {
    var Particle = Meteor.npmRequire('particle-api-js');
    var particle = new Particle();

    var particleLogin = particle.login({
        username: 'USERNAME',
        password: 'PASSWORD'
    });

    particleLogin.then(function (data) {
        return data.body.access_token;
    }).then(function (token) {
        console.log(token);
        return particle.getEventStream({
            deviceId: 'DEVICE_ID',
            auth: token
        });
    }).then(function (stream) {
        stream.on('event', function (data) {
            var eventString = data.name + ": " + data.data;
            console.log(eventString);
        });
    });
}

The console.log() works, but I get an error whenever I try to call a meteor method or insert into a mongo db.

I had a working example using spark, but it quit working in the past week - “An error occurred while getting core attrs: [Error: invalid_token]”
