The maximum resolution for images is 85 Megapixel. There are three ways to attach an asset to a message:. Please note that our servers might encode an uploaded file to ensure compatibility.

The attachment object includes the asset type image, audio, video, or file , and a payload that includes the asset url :. This allows you reuse assets, rather than uploading them every time they are needed.

For information on saving assets, see Saving Assets. Page Rate limits are in place to prevent malicious behavior and poor user experiences. Messenger API calls beyond the rate limit below will fail with error code Since the rate limit is based on the Page audience, it is possible for the same app to hit the rate limit for one Page and not another. For pages with large audiences, we recommend a send rate of requests per second. You should architect your system to distribute any sudden high amounts of load over time and are able to control your throughput should you hit our rate limits.

Be sure to catch any errors returned by the Send API including the one indicating that you've reached the rate limit. Keep it short. Consider screen size and scrolling behavior; compact messages are easier for people to follow. Try sending a few separate messages instead of one long one.

Don't use text as a substitute for images, tables, charts, and images. Structured messages or even a webview might suit your needs better. Don't write lengthy exchanges. If you need to communicate multiple things, try sending a few separate messages instead of one long one. Pay attention to quality. Use colorful images with high resolution to make your messages stand out. Starting on August 4, , people can start chatting with businesses via the Chat Plugin in guest mode without logging into their Facebook account.

This allows businesses to seamlessly connect with more customers, regardless of their browser, device, or Facebook login status. Businesses, however, will retain a copy of the conversation in their inbox even after the chat expires until they delete it.

Developers should make sure their environment prevents future messages to this conversation. Guest users will have the option to log in to Messenger to continue their chat with businesses.

We call this the "upgrade" moment for the guest user. Pages that are not linked to any developer app will have guest upgrade feature available by default. There are a couple of changes in the webhooks and API in order to support the "upgrade" moment. Subsequent message webhooks after the guest user has upgraded will only contain PSID. If the user is already logged in to their Facebook account, they will be able to start chatting with your bot right away.

If they are not logged in, a default welcome message will be display, and they will be prompted to log in or create a new Facebook account. If your Page has age or country restrictions set in Page settings, the Chat Plugin will not render for users who are not logged into their Facebook account when they visit your website. The greeting dialog state is cached on the browser and persists even when the browser is closed and reopened.

By default for each new plugin request, the greeting dialog will be shown on desktop and mobile. Users may click the close button to minimize the dialog or you can override the request default with your own display preferences. At times, it may be necessary to determine whether a user is engaging with your business using the Chat Plugin.

Setting Up the Plugin To include the Chat Plugin on your webpage, you can either use the setup tool or setup using developer steps. Pick the one you feel is right for you. Privacy : WhatsApp uses end-to-end encryption to keep your messages private. End-to-end encryption ensures that only the participants of a conversation can see the messages and content that it contains. Facebook Messenger encrypts messages by default from the sender to its server, and then encrypts them again between the server and the recipient.

Image transfer : WhatsApp enforces a limit to number of images you can send. There is no such limit on Messenger. Messenger is well integrated with Facebook and deploys facial recognition to identify your friends in the photos.

Calling : Placing calls via WhatsApp is preferred because it lets you place calls even in places where signal strength is weak.

Meanwhile, group calling is better on Messenger, especially when you need to call 50 people! WhatsApp allows you to start a group call with not more than 4 people. Design : It's a personal choice but Messenger design is a lot more modern than that of WhatsApp.
