Hi, currently, in our trackingCallback we only pass the variant_id (i.e.

0

or

1

) for user assignment data to our data warehouse and not the

variant_name

. I just wanted to check if any automated reporting where we join the metrics with the user assignment data, are they expecting

variant_id

or

variant_name

? thanks

Hi Rajiv, thanks for reaching out. Only the

experiment_id

and

variation_id

keys are absolutely required in the trackingCallback. The

variation_name

is not required by GrowthBook for analytics purposes, but if you have a custom metric that relies on

variation_name

you should include that in the trackingCallback so that it gets sent to your data source.

sorry for the late reply. Thanks!
