To start building a bot using the Messaging API, you must first create a channel on the LINE Developers console.
What's a channel?
To use the LINE platform, your application must be linked to a channel. When a channel is created, a unique channel ID is issued to identify the channel. Channels must have a name, description, and icon image.
Creating a channel
Step 1: Log in to the console
Log in to the LINE Developers console with the email address and password of your LINE account.
Note: If you do not have a LINE account with a registered email address, download the LINE app, then go to Settings > Account to register your email address.
Step 2: Register as a developer (only on first login)
Enter your name and email address to create a developer account on the LINE Developers console.
Step 3: Create a new provider
Enter a name for the provider. The provider is the entity that offers your app. For example, you can use your own name or the name of your company.
Step 4: Create a channel
Enter the required information for your channel.
Step 5: Confirm
Confirm that your channel was created.
You have now created a channel for your bot. Next, configure your channel to build your own bot or to deploy a sample bot.
