Provide exactly one of `newsletter_id` or `invite`. Neither requires following the channel; `viewer_metadata` is null when WhatsApp does not return viewer-specific metadata. ## OpenAPI ````yaml /openapi.yml get /newsletter/info openapi: 3.0.0 info: title: WhatsApp API MultiDevice version: 9.7.0 description: | This API is used for sending whatsapp via API. The web dashboard is a separate project (gowa-ui); the server downloads its latest release asset and serves it at `/` (or returns a JSON banner when APP_UI_ENABLED=false). Device scoping: - Send `X-Device-Id` on all device-scoped REST calls. - WebSocket: connect to `/ws?device_id=`. - WebSocket auth (when basic auth is enabled): browsers cannot set an Authorization header on WebSocket connections, so also pass `&authorization=` in the query string. Use TLS in production since the credential is visible in the URL. servers: - url: http://localhost:3000 security: - basicAuth: [] tags: - name: app description: Initial Connection to Whatsapp server - name: device description: Device management for multi-device support - name: user description: Getting information - name: send description: Send Message (Text/Image/File/Video). - name: message description: Message manipulation (revoke/react/update). - name: call description: Call management (reject incoming calls) - name: chat description: Chat conversations and messaging - name: group description: Group setting - name: newsletter description: newsletter setting - name: chatwoot description: Chatwoot integration for customer support paths: /newsletter/info: get: tags: - newsletter summary: Get newsletter (channel) metadata description: > Returns the channel metadata (name, description, subscribers count, verification, picture, invite code, state).
