Once you have created a LINE Official Account, you can access the LINE Official Account Manager:
The LINE official Account Manager allows you to access the various features of the LINE Official Account, including user permissions, Messaging API, and billing.
Additionally, you can contact customers using various methods, including broadcast messages, Timeline posts, and more. You can also find notifications related to your account and customize the profile screen of your account (the screen that customers see when they visit your official account).
The Sinch Developer Documentation site contains comprehensive documentation and tutorials, which show you how we support LINE through the Sinch Conversation API.
