Quick question:
Is there any way to trigger a flow or send content to a contact after the 24h messaging window has closed?
Looking for possible options like:

- One-time notification (OTN)?
- SMS or Email fallback?
- Ads JSON or sponsored message trick?
- External triggers via API or Zapier?

Would love to hear what’s working for you all
Thanks in advance!

Hi ​@FaisalRathor, The possibilities for sending messages/ flows after 24 hours window depends on the channels:

  • Messenger: You can send messages after 24 hours window if they have opted for notification list.
  • Instagram: Unfortunately there is no way to send messages after 24 hours window; you have use other strategies to have them opt-in again and keep in the 24 hours window
  • WhatsApp: You can send message templates (paid) after the 24 hours window.

Hope this helps.

Please feel free to let me know if you have any further question,

    Hi ​@sajithmohan, If I send the OTN follow-up flow via the API, do I need to provide any special key or token, or just the subscriber ID is enough?

    Thanks in advance

    Subscriber ID might be sufficient.
