Native notifications are limited to certain chats on Android devices. Beyond that no real in app notifications are possible and workarounds using external tools are required.
It seems the most popular ways are using one or the other method:
- Webview embeds: Tawk, Landbot, Intercom
- Webhook / Sheet to automation (Zapier, Integromat)
Automation can then connect to:
- text messages (Google Script for free text messages in the US)
- WhatsApp (Twilio, other WA partner or Google Sheet API)
- FB Messenger (Chatfuel, ManyChat…)
Are there any other popular methods that I missed?
