Integrate with the Prebid Analytics API
The Prebid Analytics API provides a way to get analytics data from
Prebid.js and send it to the analytics provider of your choice, such as Google Analytics. Because it’s an open source API, you can write an adapter to send analytics data to any provider you like. Integrating with the Prebid Analytics API has the following benefits:

Architecture of the Analytics API
Before we jump into looking at code, let’s look at the high-level architecture. As shown in the diagram below,
Prebid.js calls into an analytics adapter. The analytics adapter is the only part of the code that must be stored in the
The analytics adapter listens to events and may call out directly to the analytics backend, or it may call out to an analytics library that integrates with the analytics server.
For instructions on integrating an analytics provider, see the next section.
Integrate an Analytics Provider
You can integrate an analytics provider using the steps outlined below. In the example we’ll use Google Analytics for simplicity, but you can integrate any analytics provider you like as long as you have an adapter and any necessary libraries.
If you want to see how to write your own analytics adapters, look in the repo under modules.
Summary of the steps involved:
Plan the site integration
Some analytics adapters may require the publisher to load a library in the page. If this is the case for your analytics adapter, consider providing an example for users.
For example, to use Google Analytics, publishers must load the Google Analytics library:
(See the Google docs for up-to-date instructions.)
A call to
pbjs.enableAnalytics(analyticsAdapters) is needed to initialize the module(s). It should be called once on the page, after any analytics libraries have been loaded. Note that more than one analytics adapter can be loaded, though this isn’t necessarily recommended.
Prebid.js analytics module
Step 1: Prepare prerequisites for a pull request
In your PR to add the new adapter, please provide the following information:
- The contact email of the adapter’s maintainer.
- Any other information listed as required in CONTRIBUTING.md.
Step 2: Add a new analytics JS file
Create a JS file under
moduleswith the name of the bidder suffixed with ‘AnalyticsAdapter’, e.g.,
Create an analytics adapter to listen for Prebid events and call the analytics library or server. See the existing *AnalyticsAdapter.js files in the repo under modules.
There are several types of analytics adapters. The example here focuses on the ‘endpoint’ type. See AnalyticsAdapter.js for more info on the ‘library’ and ‘bundle’ types.
- endpoint - Calls the specified URL on analytics events. Doesn’t require a global context.
- library - The URL is considered to be a library to load. Expects a global context.
- bundle - An advanced option expecting a global context.
In order to get access to the configuration passed in from the page, the analytics adapter needs to specify an enableAnalytics() function, but it should also call the base class function to set up the events.
A basic prototype analytics adapter:
Analytics adapter best practices:
- listen only to the events required
- batch up calls to the backend for post-auction logging rather than calling immediately after each event.
Build the package
To add the new analyticsAdapter into a prebid package, use a command like this:
