Facebook Ads to Redshift

This page provides you with instructions on how to extract data from Facebook Ads and load it into Redshift. (If this manual process sounds onerous, check out Stitch, which can do all the heavy lifting for you in just a few clicks.)

What is Facebook Ads?

Facebook Ads are ads served up to Facebook users based on their activity, demographic information, device use information, advertising and marketing partner-supplied information, and off-Facebook activity. The platform includes reporting tools that let you see what impact your ads have.

Getting data out of Facebook

Data can be retrieved programmatically via the Facebook Ads Insights API, which is available to anyone who uses the platform. Don't confuse this with the API Facebook offers for placing and managing ads, which is not relevant to our purposes.

By following the process in the API documentation, you can make calls to the Ads Insights API to retrieve your data. You'll have access to endpoints such as impressions, clickthrough rates, and CPC, all broken out by time period.

Sample Facebook Ads data

Below is an example of what that response might look like when you query the Ads Insights API.

   "data": [
         "impressions": "1862555",
         "adset_name": "My ad set",
         "cost_per_action_type": [
               "action_carousel_card_name": "My Carousel Card 1",
               "action_type": "app_custom_event.fb_mobile_activate_app",
               "value": 0.093347346315861
               "action_carousel_card_name": "My Carousel Card 2",
               "action_type": "app_custom_event.fb_mobile_activate_app",
               "value": 0.38324089579301

Loading data into Redshift

Once you've identified all the columns you want to insert, you can use the CREATE TABLE statement in Reshift to set up a table to receive your data.

With the table built, you might think that the easiest way to migrate your data (especially if there isn't much of it) would be to build INSERT statements to add data to your Redshift table row by row. Think again! Redshift isn't optimized for inserting data one row at a time. If you have a high volume of data to be inserted, we suggest moving the data into Amazon S3 and then using the COPY command to load it into Redshift.

Keeping Facebook Ads data up to date

At this point you've coded up a script or written a program to get the data you want and successfully moved it into your data warehouse. But how will you load new or updated data? It's not a good idea to replicate all of your data each time you have updated records. That process would be painfully slow and resource-intensive.

Instead, identify key fields that your script can use to bookmark its progression through the data and use to pick up where it left off as it looks for updated data. Auto-incrementing fields such as updated_at or created_at work best for this. When you've built in this functionality, you can set up your script as a cron job or continuous loop to get new data as it appears in Facebook Ads.

And remember, as with any code, once you write it, you have to maintain it. If Facebook modifies its API, or the API sends a field with a datatype your code doesn't recognize, you may have to modify the script. If your users want slightly different information, you definitely will have to.

Other data warehouse options

Redshift is great, but sometimes you need to optimize for different things when you're choosing a data warehouse. Some folks choose to go with Google BigQuery, PostgreSQL, or Snowflake, which are RDBMSes that use similar SQL syntax, or Panoply, which works with Redshift instances. If you're interested in seeing the relevant steps for loading data into one of these platforms, check out To BigQuery, To Postgres, To Snowflake, and To Panoply.

Easier and faster alternatives

If all this sounds a bit overwhelming, don’t be alarmed. If you have all the skills necessary to go through this process, chances are building and maintaining a script like this isn’t a very high-leverage use of your time.

Thankfully, products like Stitch were built to solve this problem automatically. With just a few clicks, Stitch starts extracting your Facebook Ads data via the API, structuring it in a way that is optimized for analysis, and inserting that data into your Redshift data warehouse.
