LINE Login integration
Once LINE Login is connected, users can sign in to your service with their LINE identity in one tap—no new account or password needed. The setup has two parts: first create a LINE Login channel in the LINE Developers console, then paste the keys back into your MantaGO backend to bind it.
Step 1: Create a LINE Login Channel in LINE Developers
⚠️ Create the LINE Login channel under the same Provider as your Messaging API (LINE OA) channel.
1. Log in and create a new channel
Sign in to the LINE Developers console with an account that has LINE Developers Admin permission, then open the Provider that holds your LINE OA.
Click Create a new channel and choose LINE Login as the channel type.


2. Fill in the channel basics
Region to provide the service: select Taiwan
Company or owner's country or region: select Taiwan
Channel name: enter a name (up to 20 characters)
Channel description: enter a description (up to 500 characters)
App types: check Web app
Email address: enter a contact email
Scroll to the bottom, check I agree to the LINE Developers Agreement, and click Create to finish creating the channel
Channel icon is optional—feel free to skip it.


Step 2: Paste the Keys into MantaGO to Bind
1. Copy the Channel ID
Open the LINE Login channel you just created. Under Basic settings → "Basic information," find the Channel ID, click the copy button, and paste it into the matching field in your MantaGO backend.

2. Copy the Channel secret
On the same page, scroll down to Channel secret, click the copy button, and paste it into the field below in your MantaGO backend.

3. Set the Linked OA
Under "Add friend option," find Linked LINE Official Account, click Edit, and select the Messaging API channel you want to bind.
⚠️ Make sure the Linked OA points to the same matching LINE OA—binding the wrong account will break the features that follow.
4. Switch the status to Published
Scroll back to the top of the page, where the status next to the channel name reads Developing. Click it, then click Publish in the confirmation dialog. Once the status turns to Published, the binding is complete.


You're all set! Now Put These LIFF Features to Work
With LINE Login connected, these MantaGO features that rely on LIFF go live, letting users act right inside LINE:
Form: Fields like name, mobile, email, birthday, and address auto-fill as users complete a form, and the collected data syncs straight into your member system and Google Sheets.
Booking: Users pick an available slot in the LIFF interface, and the system pushes a reminder to both the user and the admin before the appointment.
Member center: Users self-serve to check their own form submissions, booking history, lucky-draw records, prizes won, plus their reward card and points.
Reward card: Members earn and redeem points, with in-store point QR codes tying online and offline together.
Shortlink tracking: Turn any URL into a short link and easily track how users engage with your links.
