How to Bypass Facebook Messenger’s 24-Hour Messaging Window Using Custom Webhooks

Understanding Meta’s 24-Hour Messaging Policy

To prevent spam, Meta restricts businesses from sending free-form messages to customers if more than 24 hours have passed since the customer's last interaction. Sending promotional content outside this window can result in your page getting banned. However, for transactional updates, you can securely send messages using custom webhooks and approved Message Tags.

1. Implementing Meta Message Tags

Meta allows four tags for messages sent outside the 24-hour window. These tags must be included in your API payload:

• CONFIRMED_EVENT_UPDATE: For updates regarding booking dates or appointments.
• POST_PURCHASE_RECEIPT: For sending purchase receipts, invoices, and shipment tracking info.
• ACCOUNT_UPDATE: For alerting users about changes in their registration or profiles.
• HUMAN_AGENT: Allows human support agents to respond within 7 days (requires page approval).

2. Technical Code Integration

When sending a message payload using custom Node.js webhooks, specify the tag in the Graph API call:

{
  "recipient": { "id": "PSID" },
  "message": { "text": "Your order has been shipped!" },
  "messaging_type": "MESSAGE_TAG",
  "tag": "POST_PURCHASE_RECEIPT"
}
