Insufficient Permission [403] error while modifying the Message Label using gmail API in c#
问题 I am trying to read the gmail mail message, using gmail api, and after reading the mail, I am removing the message label, so that I don't need to process it again. I am able to read the mail successfully, but when I am trying to modify the message Label ( service.Users.Messages.Modify(mods, userId, messageId).Execute(); ) then I am getting the error message: An error occurred: Google.Apis.Requests.RequestError Insufficient Permission [403] Errors [ Message[Insufficient Permission] Location[ -
