Shopify authentication using the google app script Class OAuthConfig

Question

I am trying to connect with my shopify shop through the google javascrip. The schema for authentication should be something similar to the one you can find on google documentation for twitter. I'am trying the following code, but I always get the error:{"errors":"[API] Invalid API key or access token (unrecognized login or wrong password)"}

function getInfofromshopify() {
var handle = "01-02-0316_cmt_utensili"
var urljson ="https://mysitename.myshopify.com/admin/products.json?handle="+handle;
var oAuthConfig = UrlFetchApp.addOAuthService("shopify");
oAuthConfig.setAccessTokenUrl("https://mysitename.myshopify.com/admin/oauth/access_token");
oAuthConfig.setRequestTokenUrl("https://mysitename.myshopify.com/admin/oauth/access_token");
oAuthConfig.setAuthorizationUrl("https://mysitename.myshopify.com/admin/oauth/authorize");
oAuthConfig.setConsumerKey(API_KEY);
oAuthConfig.setConsumerSecret(Shared_secret);
var options =
{
"oAuthServiceName" : "shopify",
"oAuthUseToken" : "always"
};
var response = UrlFetchApp.fetch(urljson,options);
var responsestr = response.getContentText();
var result = Utilities.jsonParse(responsestr)
}

This worked for me:

var url = "https://<YOUR_SHOP>.myshopify.com/admin/products.json";
var username = "<YOUR_SHOPIFY_API_KEY>";
var password = "<YOUR_SHOPIFY_API_PASSWORD>";
var response = UrlFetchApp.fetch(url, {"method":"get", "headers": {"Authorization": "Basic " + Utilities.base64Encode(username + ":" + password)}});
