Amplitude

You can integrate Flagsmith with Amplitude. You can automate AB tests by connecting the Flagsmith platform with Amplitude. The process is as follows:

Integration Setup​

  1. Get the Amplitude API key for your Amplitude project from the Amplitude Project page (Settings > Projects > Your Project > General tab)
  2. Add the Amplitude API key into Flagsmith (Integrations > Add Amplitude Integration)
  3. All API calls generated by the Flagsmith SDK to the Get Identity Flags endpoint will send the a full set of flag evaluations for that particular user to the Amplitude Identify endpoint

How it Works​

tip

For flags that contain remote config values, Flagsmith will pass the value of the flag to Amplitude if the flag is enabled. If the flag has no remote config value, Flagsmith will just pass the boolean state for the flag.

Identity flag values are passed into Amplitude.

Here's a demo user in Flagsmith:

Amplitude

If we make the call to the Flagsmith API to get the flags for this user:

curl 'https://edge.api.flagsmith.com/api/v1/identities/?identifier=development_user_123456' \
  -H 'x-environment-key: 8KzETdDeMY7xkqkSkY3Gsg'

And then take a look in our Amplitude dashboard, you can see the user and the flag data that has been sent to the Amplitude platform.

Use Case​

Once the integration has been set up, you can start segmenting your Amplitude identities based on the flags that they saw. This means you can run AB tests driven by Flagsmith segments, and have the data show up automatically in Amplitude.

Integration Notes​

You have to identify users on both platforms in the same way. The Flagsmith Identity ID must be the same as the Amplitude user_id.
