Parameter history

  • v1.12: Introduced auprop=registration

Additional notes

  • This API call is case sensitive, so aufrom=DROV doesn't return the same results as aufrom=Drov.
  • All registered usernames are saved and retrieved in capitalized form. If you are using aufrom or auprefix in your query, make sure you are passing them values that start with an uppercase character.
  • Although the default behavior is to list any user in the database, we can also limit our response to only those users who belong to a certain group, such as sysops, or bots. User groups are how MediaWiki grants users certain rights and privileges; see Help:User rights and groups for more details on how this system works.
