I used JSON.Stringify() to look at the data when I was console.loggining so that was the reason why my object were turning into strings

JSON.stringify()

correct… u converted the object to a string… don’t need to do that

just pass the object from helper up to module …

then it will use the this.data.name

This line of code will show a { on my mirror so I’m assuming everything is turned into a string?

I used JSON.stringify() in my node_helper file

            wrapperDataRequest.innerHTML = this.data[0];

 getDom: function() {
        var self = this;
        var wrapper = document.createElement("div");
        //If this.dataRequest is not empty
        if(this.data && this.data.length > 0){
            console.log("MMM-Test: This.data is set" + this.data);
        
            //Name of Business
            var wrapperDataRequest = document.createElement("h1");
            wrapperDataRequest.innerHTML = this.data;
            wrapperDataRequest.className = 'yelpBusinessName';

            wrapper.appendChild(imgDataRequest);
            wrapper.appendChild(wrapperDataRequest);
        } else {
            console.log("MMM-Test: this.data couldn't be found");
            wrapper.innerHTML = "This didn't work";
        }
        
        return wrapper;
	},

MMM-Test: This.data is set{"id":"E8RJkjfdcwgtyoPMjQ_Olg","alias":"four-barrel-coffee-san-francisco","name":"Four Barrel Coffee","image_url":"https://s3-media1.fl.yelpcdn.com/bphoto/-_Ks4eF8aZcm3GZgUf5Urg/o.jpg","is_closed":false,"url":"https://www.yelp.com/biz/four-barrel-coffee-san-francisco?adjust_creative=joufChkTQP-Ru-G_5cRrMA&utm_campaign=yelp_api_v3&utm_medium=api_v3_business_search&utm_source=joufChkTQP-Ru-G_5cRrMA","review_count":2069,"categories":[{"alias":"coffee","title":"Coffee & Tea"}],"rating":4,"coordinates":{"latitude":37.7670169511878,"longitude":-122.42184275},"transactions":[],"price":"$","location":{"address1":"375 Valencia St","address2":"","address3":"","city":"San Francisco","zip_code":"94103","country":"US","state":"CA","display_address":["375 Valencia St","San Francisco, CA 94103"]},"phone":"+14158964289","display_phone":"(415) 896-4289","distance":1452.8696502343696}

How can I display name?

I tried this.data[0].name or this.data.name but no luck

Something important to remember:
Sometimes, e.g. when you use a callback function, note that the this reference may change (better: the context changes).
Therefore you will often see something like this in the module codes early in a function:

self = this

And later on in the callback function

self.config.requestToken

Here, the “this” instance that is bound to its context, gives it’s properties to the global variable “self” that can then be used in any context (because it is global).

For (much) more information check out https://scotch.io/@alZami/understanding-this-in-javascript

However, is there a way to put my request token inside of the request header?

MMM-Strava.js (the main js file)

Module.register("MMM-Strava", {
    // Default module config.
    defaults: {
        client_id: "",
        client_secret: "",
        period: "recent",   
        ...

config.js:

        //disabled: true,
        module: 'MMM-Strava',
        position: 'center',
        config: {
            client_id: "my_id",
            client_secret: "hereisthesecrethidden",

My main.js or into my node_helper.js?

Neither nor.
You would create a string variable for both in the module defaults.
THen in config.js which is only present on your device and not shared via github or else, you can overwrite the empty variable with your api_key and secret.
There are loads of examples, a few coming to my mind are MMM-Strava or MMM-DarkSkyForecast (or nearly any other weather app.
