- TL;DR: This page explains how to create a LINE channel configuration, from the interface or the API, so that Journey Optimizer can authenticate with the LINE Messaging API and send messages to your customers.
Intents:
- Create a LINE channel configuration from the Channel configurations menu
- Associate consent policies to the configuration through marketing actions
- Choose the message type (Marketing or Transactional) for the configuration
- Map the LINE user ID and define the Sender Name
- Configure the LINE Channel settings through the API
Glossary:
- Channel configuration: The configuration created from Channels > General settings > Channel configurations that defines how Journey Optimizer connects to and sends messages through a channel (product-specific)
- Marketing action: The setting used to associate consent policies to the messages using this configuration, so that customer preferences are respected (product-specific)
- Channel settings: The connection settings that store the authorization and configuration details for connecting to the LINE Messaging API (product-specific)
- LINE user ID: The identifier used to link messages to individual users within your LINE channel (product-specific)
- Sender Name: The name, such as your brand’s name, entered for the configuration (product-specific)
Guardrails:
- Configuration names must begin with a letter (A-Z) and can only contain alphanumeric characters, underscore, dot, and hyphen.
- Marketing messages require user consent and should comply with LINE’s policy regarding user opt-ins.
- Transactional messages can be sent even to users who have unsubscribed from marketing communications but are strictly limited to specific transactional contexts.
- The LINE user ID mapped here must already exist on your customers’ Real-Time Customer Profile.
- Channel settings must be set up by reaching out to your Adobe representative.
- The API uses headers including a user token from your technical account, the client ID from Adobe Developer Console, the IMS Organization ID, the sandbox name, and Content-Type application/json.
Terminology:
- Canonical name: LINE channel configuration — Acronym: n/a — variants: channel configuration
- Do not confuse: “Marketing” (promotional messages requiring user consent) ≠ “Transactional” (non-commercial messages limited to specific transactional contexts)
- Do not confuse: “Channel settings” (authorization and connection details for the LINE Messaging API) ≠ “Marketing action” (associates consent policies to the configuration)
