i am trying to create line chatbot with several functions in it. One of the function need to know the user LINE ID (for example: ryan123) not user id (U858382312321123......). I am using google app script to create the line chatbot
is it possible to get user LINE ID using API? or is there any way to get this through line bot?
/profile/{userId} is the only* way you can get displayName
*though there endpoints to get the profile with userId by further specifying the groupId or roomId
In case your Messaging API bot is a verified or premium account, you can use a list of userId of followers at anytime with followers/ids
Otherwise, you need to store them upon follow, messsage, etc. events
