Transaction: If one group attribution is not parsable, we raise you an
error and import nothing. You have to fix your payload and send it to us again.
And if the answer is a success, it means that every group attribution you sent
us have been upserted
Conflict Rule and upsert: Be careful, each user can only have one group by
dimension for a given period. Given new attributions dates will override
conflicting dates already present in Qobra.
Also, if you send a payload with two groups attributions for the same user over
the same period we’ll send you back an error.
Limit: you can’t update more than 200 group attributions at a time.
Error behavior: In case of any error, your group attributions wont be upserted
