UserData is used for Customer Match and store sales uploads. In a given create/remove UserData operation, each set of user_identifiersshould be for a single user.
Note that the same total amount of data can be sent in a single request, but each set of user_identifiers must represent a single person.

The next API version will no longer accept KeywordMatchSetting for campaigns.
Existing API versions will ignore the value sent for the optIn field of KeywordMatchSetting.
Regardless of the optIn field value, all exact and phrase match keywords will match close variants.
Close variant matching is already enabled by default for new campaigns, so if you haven't specifically set the optIn field, you won't see any changes in keyword matching behavior.
