LINE Notify service registration

After creating an account, go to the LINE Notify Official Site and log in with your LINE account. At that time, you will be logged in with the email address registered in your LINE account, so you need to register in advance.
From the LINE Notify Registration Service Management Page, enter the necessary information such as the service name and service outline to register the service.
From LINE Notify My Page, specify the token name and the talk room to send the notification, and get the access token information. After getting the access token, LINE Notify will be registered as a friend of the talk room.

Please refer to the following site for e-mail address registration.
