Authentication

To use LINE tools, you need a LINE Channel Access Token from the LINE Messaging API. Note: Treat API keys as sensitive information and never commit them to public repositories. For setup instructions, see the LINE credentials guide.

​
Setup

​
1. Create a LINE Official Account

  1. Visit the LINE Developers Console
  2. Create a new Provider if you don’t have one
  3. Create a new Messaging API channel

​
2. Get Your Channel Access Token

  1. Open your channel in the LINE Developers Console
  2. Go to the Messaging API tab
  3. Scroll to Channel access token (long-lived) and click Issue
  4. Copy the token — this is your LINE_API.channel_access_token

​
3. Add LINE Credentials to JinbaFlow

Add your token as a secret in JinbaFlow with key LINE_API: 
{
  "channel_access_token": "YOUR_CHANNEL_ACCESS_TOKEN"
}

  • The LINE Developers Console (for test users)

​

  • Statistics are available from the day after the reference date

​
Demographic Data Notes

LINE_GET_DEMOGRAPHIC requires at least 20 friends in your account before data becomes available. The available field in the response indicates whether data is ready.
