Connect LINE to your studio's system

A step-by-step guide to setting up Messaging API and LINE Login, so the system can send messages in the chat and members can log in to the app with their LINE account. You set it up once, with the owner's LINE account.

https://

What you'll have when you're done

Two channels in the same Provider. One is linked to the LINE Official Account to send messages. The other lets members log in and open the member app.

Provider: the studio's company name

Messaging API channel

Linked to the LINE Official Account. Sends booking confirmations, class reminders and instructor alerts.

Webhook URL

https://booking.yourstudio.com/api/webhook

LINE Login channel and LIFF app

Members log in with their LINE account and open the member app from the chat menu.

Endpoint URL

https://booking.yourstudio.com/liff

What you need

  • The owner's LINE account, which is an admin of the LINE Official Account.
  • The studio's LINE Official Account. If you don't have one yet, sign up in LINE Official Account Manager.
  • The studio's domain, already pointing to Cloud. See the Cloud page
  • The company or business name, for naming the Provider.

Both channels must be in the same Provider

LINE gives each user a separate ID in each Provider. If LINE Login and Messaging API are in different Providers, the system can't message members who log in through the app, and a channel can't be moved to another Provider later.

Part 1

Messaging API

Lets the system send booking confirmations, class reminders and instructor alerts through the studio's LINE Official Account.

Step 1

Enable Messaging API

  1. 1Open LINE Official Account Manager, choose the studio's account, go to Settings, then choose Messaging API.
  2. 2Click Enable Messaging API.
  3. 3Choose the Provider to use for both channels, or create a new one named after your company, then click OK.

Once you choose a Provider, you can't change it later. Check the name before you click OK.

Since 2024, LINE no longer lets you create a Messaging API channel directly in the LINE Developers Console. You can only enable it from LINE Official Account Manager.

Part 3

Send the values to Svana and set up the Rich menu

The Svana team adds all the values to the studio's system. Then set up the chat menu to open the member app.

Step 10

Send all 7 values to the Svana team

Tick off each value as you collect it, then send them all at once.

Send them only through the method the Svana team gave you. Don't paste these values into group chats or emails that many people can see. If a value gets out, issue a new one in the Console and tell the team again.

When the team confirms the values are in, go back to step 4 and click Verify again.

Step 11

Set up the Rich menu to open the member app

  1. 1In LINE Official Account Manager, go to Rich menus, click Create, then choose a template.
  2. 2Set each area's Action to Link, pointing to the LIFF URL followed by the page you want.

Use the studio's LIFF ID in place of the sample. LINE opens the page added at the end of the URL inside the member app.

Step 12

Test before you tell members

  1. 1Open the studio's chat on your phone, tap the menu and log in with LINE. The member app should open on the studio's domain.
  2. 2Book one class and check that a confirmation arrives in the chat.
  3. 3Have an instructor type the activation phrase in the chat, such as Activate Instructor, to link their instructor account. Then try booking one of that instructor's classes.

Messages the system sends to members count toward the message quota of the studio's LINE Official Account plan.

If something goes wrong

Verify doesn't show Success

Check that the URL starts with https and ends with /api/webhook, matching https://booking.yourstudio.com/api/webhook, and that the Svana team has added the Messaging API Channel secret.

Members can log in but don't get messages in the chat

Check that LINE Login and Messaging API are in the same Provider, and that the member has added the Official Account as a friend and hasn't blocked it.

Admins can log in, but no one else can

The LINE Login channel is still Developing. Go back to step 9.

The app opens to a blank or wrong page

The LIFF Endpoint URL must be https://booking.yourstudio.com/liff, and the domain must already point to Cloud.

Members get two replies to one message

Auto-reply messages is still on in Response settings. Go back to step 5.

Screens in this guide are illustrations. Menu names follow the English versions of the LINE Developers Console and LINE Official Account Manager, and the real screens may differ slightly. For more detail, see Messaging API and LIFF in the LINE documentation.
