// ChannelLINE represents a LINE Official Account channel configuration.
|
|
// Reference: LINE Messaging API — https://developers.line.biz/en/docs/messaging-api/
|
|
//
|
|
// GoChat addition — LINE Messaging API integration.
|
|
// The LINE channel connects LINE Official Accounts to gochat conversations.
|
|
//
|
|
// Key LINE API concepts:
|
|
// - Channel Access Token: long-lived token for API calls (renewable)
|
|
// - Channel Secret: used for webhook signature verification (HMAC-SHA256)
|
|
// - LINE Login: OAuth2 flow for user authentication (optional)
|
|
// - Webhook URL: where LINE sends event notifications
|
|
//
|
|
// Design notes:
|
|
// - Uses GORM soft-delete pattern consistent with other channel models
|
|
// - JSON field tags follow snake_case convention per P2D §7
|
|
// - Channel-specific fields (channel_access_token, channel_secret) are stored
|
|
// in Inbox.ChannelConfig rather than in this model, keeping the model lean
|
|
// per the Chatwoot pattern where channel_type specific config lives in the polymorphic association
|
|

|

// config stored in Inbox.ChannelConfig (JSONB).
