User:Zaycodes/Sandbox/API:ClearHasMsg/en

GET request to clear  flag for the current user.

Additional notes

 * The  action will remove the HasMsg flag, which causes the   banner to appear and returns true in HasMsg query. It can be used by applications that retrieve the talk page using the API, which unlike opening your talk page in a browser, doesn't automatically remove this flag.
 * When you trigger this action, the banner  will not appear until you receive any more messages from other users.
 * This module must be POSTED since 1.29.0-wmf.5.
