Aug 04, 2020 - V8.0

  • Introducing updates to the Facebook Chat Plugin (formerly known as the Customer Chat Plugin) – Today, we are introducing a new and improved design, and the Chat Plugin now connects businesses to all users on their websites, even if they are not logged into Facebook. To ensure optimal user experience, we recommend that developers read the new webhooks that detect if a user is messaging the business in guest mode, and when the guest session is terminated.
  • Shops API - We are launching support for sending and receiving products on Messenger for Shops. This includes the Product Template that can be used to send products in messages, product details page (PDP) referral info in message webhook, Product XMA support in Conversation API, webhooks for messages with product template and messages from Facebook Shops Product Detail Page, and echo webhooks for messages with products.
  • App Review Submission Changes - We have merged the Messenger app review process with the main app review and provided instructions in a sample submission.

The following changes take effect on v8.0+ today and will affect all versions on Aug 4, 2022

  • Nested Persistent Menu - Messenger Profile API and Customer User Settings API will not support nested menus on v8.0 and above. Additionally, these APIs will allow creating flat (single level) menus with up to 20 items. The latest Android app will flatten nested menus, just as the iOS app does.

Today, we are sharing a new effective date for the policy changes that we announced on August 29, 2019 to give developers and businesses additional time to prepare for the policies and incorporate new messaging features. The new policy will now go into effect on March 4, 2020. For more details, see the Messenger Platform Policy Overview

The breaking change announced on October 29, 2019 affecting Broadcast API and Legacy sponsored messages has been set for March 4, 2020.

Based off feedback from our community, we identified additional use cases aligned with our policy principles that were not covered under the original set of message tags. Thus, we are planning to introduce a “one-time notification” API in February.

Policy Update

The Messenger Platform’s policies are designed to help people and businesses connect in ways that drive meaningful outcomes. At the heart of this is the understanding that people and businesses need a seamless, reliable way to get something done - whether it is getting a question answered, making a purchase, or communicating important and relevant updates. The following policy update is designed to make communication between people and businesses on Messenger relevant, important and timely.

Apps have until March 4, 2020 (Updated on December 20, 2019) to migrate to the new policy. We highly encouraged developers to adopt these policies right away to ensure a smooth transition. See Messenger Platform Policy Overview

Effective March 4, 2020 (Updated on December 20, 2019).

  • Revised Standard Messaging Window Policy: We are updating our policies to a 24-hour standard messaging window. We know that people expect businesses to respond quickly and, not surprisingly, businesses that respond in a timely manner to achieve better business outcomes. To improve the people to business experience, businesses will no longer be able to send a message outside the 24-hour window as part of the standard messaging window policy.
  • Introducing More Streamlined Message Tags: We are simplifying message tags. Message tags enable businesses to send personalized, 1:1 messages to people outside of the standard messaging window. Message tags are now available for the following use cases: post-purchase updates, event reminders, and account updates, and human agent (closed beta).
  • Effective Audience Reengagement Outside 24-Hour Message Window: Businesses who want to send one message to many people, which may include promotional content, outside the standard messaging window, have the opportunity to use sponsored messages. Sponsored messages are a great way for businesses to re-engage people who currently have an open chat with the business.
  • Subscription Messaging Beta Update: We are updating this policy as we found some businesses were using the subscription messaging beta in ways that weren’t in line with our policy and led to a poor experience for people and other businesses. Moving forward, subscription messaging will only be available for news organizations who successfully register their Pages through the Facebook News Page Index to help improve the user experience and business outcomes.

For more details, see the Messenger Platform Policy Overview

Discovering Businesses on Messenger As a part of our continued commitment to simplify the Messenger experience for people, we are removing the Discover tab from the Messenger app. We will continue to invest in more and better ways to help businesses connect with their customers wherever they are, including updates to m.me links, various entry points across our family of apps, as well as ad products that lead to Messenger.

July 29, 2019 - V4.0

  • M.me links now reopen the 24hr window within existing threads. When a person clicks an m.me link that contains a ref parameter and is taken into an existing thread, it will now reopen the 24hr standard messaging window. This will allow apps powering Pages to reply to people based on the context that the ref parameter provides.
  • Messenger rate limit - The new rate limit is now tied to the number of people a Page can send messages to. Enforced on v4.0+ and will apply to all versions on October 29, 2019.

The following APIs are deprecated on v4.0+

Breaking Changes

The following APIs are deprecated on v4.0+ and will be removed from all versions on October 29, 2019

June 10, 2019

During F8 2019, we announced our plans to launch a lighter, better and simpler Messenger designed to build closer connections between people and businesses. Starting August 15, 2019, updated versions of the Messenger app will reflect the following changes:

Won't render on the new app

  • Location quick reply which allows people to send their location in the Messenger thread will no longer be rendered. We recommend businesses ask for zip code and address information within the thread. While we are sunsetting the existing version of Share Location, in the coming months we will be introducing new ways for people to communicate their location to businesses in more valuable ways.
  • Share Button within the media, list and generic templates will no longer render. People can use the Messenger forward functionality instead of the Share Button.

Won't function with the new app

  • Begin share flow Messenger extension SDK that allows developers and businesses to trigger a share experience from a webpage that loads within Messenger . As a workaround, developers can generate a link using the context in the webview and provide a way for user to copy the link and share it in the Messenger conversation.
  • Share to Messenger SDK that allows people to share links and media from apps to Messenger will no longer be supported. Businesses and developers might need to make modifications to their app to trigger native OS sharing. People will be able to share content to Messenger using the native sharing features that is built into their devices.
  • Messenger Codes the Messenger camera will no longer support scanning these codes. We believe this experience will be more seamless by leveraging the phone's native capabilities to scan QR codes with m.me links.

Will render differently in the new app

  • Vertical list templates will no longer be supported. Instead, we recommend businesses use the horizontal scrollable carousel template. Vertical list templates will render as horizontal scrollable carousel template post August 15th.
  • Nested menu will no longer be supported. To create a more seamless experience for people on Messenger, we are transitioning from nested persistent menu to a single layer menu format. We believe this will create an even better experience for people on Messenger. Nested menu items will render as a flat list.
  • Open Graph template which allows people to play songs inline within Messenger will no longer be supported. As a fallback, we are rendering the generic template which links to the URL. When a user clicks on the song that is shared in Messenger, the user will be directed to the audio streaming platform's website or app.

Messenger Bot Reviews will be removed on August 15, 2019. They allowed people to leave a star rating and review for a bot. Page owners will no longer be able to view these ratings for their app and Page in the Page Settings or in App Dashboard.

May 08, 2019
