Exporting Leanplum A/B Test information to Other Analytics Providers

This guide describes the method in which to get a/b test information (the users in the test and which variant they fall within) into other analytics providers. 

At the beginning of each user's app session, Leanplum assigns a Variant ID for each A/B test that is applicable for the user. For example, suppose a user qualifies for two tests:

  • Test A
  • Test B
Suppose the user is assigned "Variant 1" on "Test A" and "Control" on "Test B". Leanplum will give the user two variant IDs: 6331369890775040 and 5702495255396352. 
 
Note: The app only has the Leanplum Variant IDs for several reasons:
  • It is more efficient for the app to only receive the numeric IDs, because they are more compact than receiving the entire test name and variant name.
  • The test names and variant names can be changed later in the dashboard, which would cause data to not match. The numeric Variant IDs are persistent and guaranteed unique.
  • For security, we do not want the end user to be able to see the names of the A/B tests or variants.
Two Export Options
  1. Use Leanplum's API to extract users' variant ID for Test A and Test B. Use the exportUsers call
  2. The SDK start call response returns the variables that have changed for the user - Have the SDK pass this response to your backend. Start call response
Translating IDs into readable formats
Next you may want the ability to map these numeric variant ids into human-readable names.
 
Leanplum provides an API that gives you information on translating Variant IDs back into human-readable names. The most comprehensive API call is getAbTests.
 
This will return information about all A/B Tests and Variants for a specific app. From this information, you can determine that 6331369890775040 is "Variant 1" in "Test A" and 5702495255396352 is "Control" in "Test B".
