Pull Stock Quotes Into AdWords Scripts Using Yahoo! Finance API

I was recently asked on Twitter if I had ever seen a script that used stock market performance to adjust bids. Honestly I never have, but I have been asked about this ability multiple times. So I thought I'd build something to do just that.

Finding a reliable and free API for stock data is a little difficult, but everyone seems to point to a somewhat hidden Yahoo! Finance API. Despite the fact that there are multiple libraries built around it, I couldn't find much in the way of documentation other than a StackOverflow post that talks about it. So long story short, this API could stop working at anytime, so use at your own risk.

Here is some sample code to get you started using this. The code below simply looks up a few quotes (one from Bitcoin) and loads them into a Google Spreadsheet of your choosing. Pretty straightforward. The one confusing thing is the "f=" parameter that you need to pass to the API. It is documented a little bit in this blog post but is still pretty confusing. It is a string of one or two character codes that is used to define the columns you want to return. For most people, the symbol, name, and current price should be enough. Feel free to customize it as needed.

* Yahoo Finance API Class Example
* Version 1.0 
* Created By: Russ Savage
function main() {
  var yfa = new YahooFinanceAPI({
    symbols: ['^GSPC','VTI','^IXIC','BTCUSD=X'],
    f: 'snl1' // or something longer like this 'sl1abb2b3d1t1c1ohgv'
  for(var key in yfa.results) {
    Logger.log(Utilities.formatString('Name: "%s", Symbol: "%s", Last Trade Price: $%s', 
  var includeColumnHeaders = true;
  var sheetData = yfa.toGoogleSheet(includeColumnHeaders);
  var ss = SpreadsheetApp.openByUrl(sheetUrl).getActiveSheet();
  for(var i in sheetData) {

Just copy the follow code into the bottom of your AdWords script and you should be good to go.

executeInParallel on More than 50 Accounts Using Labels

One of the biggest limitations for people running MCC level scripts is the 50 account limit imposed by the executeInParallel function. Until recently, one of the ways to get around this limit was to store the processed accounts list on Google Drive and update the file when needed.

Recently, the AdWords Scripts team enabled the ability to apply labels to each account from the MccApp object. With this, we gain the ability to write a much cleaner version of the script that uses labels to indicate when each account has been processed. Using this method and running this script every hour, you could process up to 1,200 accounts per day.

The following code is meant to provide a framework for you to substitute your own MccApp code into. You can then schedule this code to run every hour, and it will continue processing the accounts in your MCC until each one of them is finished.

It will also attempt to notify you when there are accounts that return an error so that you can investigate. The one caveat about this script is that if you run into timeout limits on the Mcc level, namely in the results function, you might not apply the label to each successfully completed account. You can solve this by replacing line 76 with the following and removing line 89:


Anyway, I hope this helps and let me know if you run into any issues in the comments.

Use Google Feed API to Convert RSS to JSON

Here is a quick tip for anyone sick of working with the xml in RSS feeds. You can use the Google Feed API in your scripts to automatically convert the XML in the RSS feed to JSON which makes working with them much easier. For example, there is an RSS Feed from the Consumer Product Safety Commission and it has all the government recalls in the United States. Using this simple trick, you could easily pull the fresh feed on a regular basis and parse out information about recalls to use in your account. You can also configure Google Alerts to generate RSS feeds based on specific keywords you are interested in. For example, here is an RSS feed for the keyword "smx".


* Use Google Feed API to convert RSS to json
* Version 1.0 
* Created By: Russ Savage
// Usage: var jsonData = convertRssToJson('');
function convertRssToJson(rssUrl) {
  var FEED_API_URL = ""
  var url = FEED_API_URL+encodeURIComponent(rssUrl);
  var resp = UrlFetchApp.fetch(url);
  if(resp.getResponseCode() == 200) {
    return JSON.parse(resp.getContentText());
  } else {
    throw "An error occured while trying to parse: "+rssUrl;

Pull Salesforce Data into AdWords Using Scripts

After my post about importing Zoho CRM data into AdWords, I received a lot of comments about doing something similar for Salesforce. I finally had some time to build a simple class that allows you to query data and objects from your Salesforce instance and use it in your scripts.

First, we will need to set you up with some OAuth credentials, and for that, you need to set up a new connected app in Salesforce. It is in slightly different places in each version, but using the developer version, I was able to find it under Setup > Build > Create > Apps. From there, all the way at the bottom, you can see a section for Connected Apps.
Creating a new connected app

If for some reason you can't find it in your Salesforce instance, your admin may not have given you access to it. Hopefully, they can help you.

After clicking the new button, you will need to fill out a few required fields and then select the option to "Enable Oauth Settings." You will need to enter a callback url but we won't be using it so you can enter any url that starts with https. For "Scopes", I just said "Full Access" but you may have to talk to your Salesforce Admin about that one. We will only be reading from Salesforce so it shouldn't be an issue.
Enabling the OAuth Settings

That's all you need to fill out and you should have a new app created. The important thing here is the "Consumer Key" and the "Consumer Secret" that you will need for the script to connect to your Salesforce instance.
Salesforce Consumer and Secret Keys

The last thing you will need from your Salesforce instance is a security token. You may already have one in which case, you can skip this. But if not, you can reset it under My Settings > Personal > Reset my Security Token. It will email you a new token.
Reset your Security Token

Ok, now we are finally ready to get to the AdWords Scripts code. The following code will set up a new SalesforceAPI object and query the most recent Opportunities that were Close Won so that you can use that revenue in your AdWords account.

It's that simple. If you want to get all the information about a particular object after you query for it, you can use the function getObjectByUrl() and send it the url from the query results. To learn more about the query syntax, check out the Salesforce SOQL documentation.

There are a few caveats for this code. Every Salesforce installation is unique so there really is no way for me to really troubleshoot issues with your specific install. This code was tested on a fresh Salesforce for Developers account so your results may vary. You will probably have more luck contacting your Salesforce Admin than leaving a comment here. Also, you may notice that the code it using the least secure option to log into Salesforce. This code with your username and password will be accessible to all users of your AdWords account, so be careful. It might be better to create a special Salesforce user with very limited permissions for something like this.

If you think this is useful, come let me know at SMX East this week.
