Prerequisites

Before starting the LINE integration setup, ensure you have:

Required

Fiko Admin Access — Admin role in your Fiko account
Business Verification — Verified business status (for some features)

Helpful to have

Important Notes

• LINE Official Account creation may require business verification
• Some LINE features are region-specific and may vary by country
• Webhook URL setup requires your Fiko account to be active

Setup Process

The LINE integration setup involves creating a LINE Developers account, configuring your Official Account, and connecting it to Fiko through a secure 8-step wizard process.

Create LINE Developers Account

Start by creating a LINE Developers account, which will give you access to the LINE Business platform and Official Account management tools.

Go to developers.line.biz and click "Start Now"
Sign in with your LINE account or create a new one if needed
Complete the developer registration form with your business information
Verify your email address through the confirmation email
Accept the LINE Developers Terms of Service

Your LINE Developers account will be the central hub for managing all your LINE integrations and Official Accounts. Keep your login credentials secure.

Create Provider and Channel

Create a provider (your business entity) and a Messaging API channel that will handle communication between LINE and Fiko.

Create Provider:

In the LINE Developers Console, click "Create Provider"
Enter your business name as the provider name
Add a description of your business or service
Click "Create" to establish your provider

Create Messaging API Channel:

Click on your newly created provider
Click "Create Channel" and select "Messaging API"
Fill in: channel name, channel description, category, and subcategory
Review and accept the terms, then click "Create"

Configure Channel Settings

Set up webhook URL and generate access tokens for secure communication.

Channel Configuration:

Open your Messaging API channel from the provider dashboard
Go to "Basic Settings" tab and note your Channel ID and Channel Secret
Navigate to the "Messaging API" tab
Generate a Channel Access Token (long-lived)
Copy the access token — you'll need it for Fiko integration

Enable Webhooks in Response Settings:

Go to LINE Official Account Manager → Settings → Response settings
Under Toggle responses, find the Webhooks toggle and enable it

Enable Webhook in Developers Console:

In the "Messaging API" tab, find the "Webhook Settings" section
Set "Use webhook" to "Enabled"
Leave the webhook URL empty for now — Fiko will provide this

Important: Keep your Channel Secret and Access Token secure. Never share these credentials publicly or commit them to version control.

Ensure "Use webhook" is set to "Enabled"
