Businesses will have up to 24 hours to respond to a user. Messages sent within the 24-hour window may contain promotional content. Users have the option to block or mute a conversation with a business at any time.

Here are examples of the user actions that open the 24 hour Standard Messaging window:

• The user sends a message to the Page
• User clicks a call-to-action button like Get Started within a Messenger conversation
• User clicks on a Click-to-Messenger ad and then starts a conversation with the Page
• The user starts a conversation with a Page via a plugin, such as Send to Messenger plugin or the Checkbox plugin.
• User clicks on an m.me link with a ref parameter on an existing thread
• User reacts to a message. See Replies and Reactions

For information on how you may be able to send messages outside the 24-hour messaging window, see Message Tags, and Sponsored messages.

One-time Notification (LIVE on SegMate)

Learn more here: https://help.segmate.io/article/72-how-to-use-one-time-notification-request-otnr-for-facebook-messenger

Messenger Platform's One-Time Notification API (Beta) allows a page to send a time-sensitive and personally relevant notification for use cases (e.g. back in stock alert) where someone has explicitly requested to receive a one-time follow-up message. Once the user asks to be notified, the page will receive a token which is equivalent to permission to send a single message to the user. The token can only be used once and will expire within 1 year of creation. Learn more here

Private Replies (Post Engage in SegMate)

When users create a Post Comment or a Visitor Posts on a Page, Private Replies allows the Page to send a single message as a reply. Private replies are currently allowed within 7 days of the referenced user action. Along with the message sent, the user will also receive a reference to their Post Comment or Visitor Posts.

Message Tags and Messaging types (Non-Promotional Tags)

Message tags enable sending important and personally relevant updates to users outside the 24-hour Standard messaging window, for a set of approved use cases. For complete details on allowed use cases, see the list of supported Message Tags. The use of tags outside of approved use cases may result in restrictions on your ability to send messages.

News Messaging (Subscription Messaging - For News Outlets Only)

News messaging applies to news content only, and must not be used for promotional content, including but not limited to subscription offers, deals, coupons, discounts, or content produced by or that promotes a third party (e.g., branded content, affiliate marketing). The use of news messaging outside of these approved use cases may result in restrictions on your ability to send news messages.

Due to the global COVID-19 pandemic, select nongovernmental health organizations that are fundamental to the global fight against this disease and Governmental Health Entities that enable messaging, support, and services for the treatment of this global health crisis may temporarily be allowed to use this permission to provide messages directly related to the global health crisis. Note that access is limited and subject to Facebook approval; all policies including spam rates, Platform Policies, and Community Standards apply; we reserve the right to remove access at any time, and to set additional criteria including restricted usage above and beyond our existing policy set.

Sponsored Messaging

Sponsored messages allow businesses to reengage with people who have an open conversation with their Page in Messenger. Sponsored messages can be sent outside the 24-hour standard messaging window and can include both promotional and non-promotional content. Sponsored messages are annotated in the conversation with the word 'Sponsored' above the message.

Sponsored message content must comply with Facebook advertising policies.
