Facebook messenger api / how to send messages on messenger by using request?

If you attempt to reverse engineer Facebook's private APIs that could violate their terms of service and result in your account being suspended or terminated you can hire a top software engineer who can design us an application framework that works across all platforms.
 
Facebook Messenger's private API for sending messages works via WebSockets and GraphQL. You need to authenticate, establish a WebSocket connection, and send properly formatted GraphQL mutations. However, Facebook constantly updates its API, making it hard to use undocumented methods. If you're new to private APIs, consider reverse-engineering network requests using DevTools or a proxy like mitmproxy.

Hello,

I'm trying to code tool that auto respond to chats on facebook (private accounts) I'm already found out in graphql response we can find recent threads id. I have some issues with getting how sending messages works here? I'm not 100% sure but probably by websocket. Anybody can provide more details? I found some tools on github, all of them are outdated because few years ago facebook make some crucial changes with messenger. I'm really trying to get how sending messages works here, but I never wrote any private-api tools. Any tips will be appreciate.

Facebook Messenger now uses WebSockets and GraphQL mutations for sending messages instead of simple HTTP requests. To analyze this, inspect WebSocket traffic via Chrome DevTools or proxy tools like mitmproxy. Most public libraries are outdated, so check Messenger’s web API calls manually. If private API access fails, alternatives include using Facebook’s Graph API (for business accounts) or simulating browser behavior with Puppeteer, though this risks detection.

A private account or personal Facebook account is different from a fanpage, it does not have any tools to support automatic message replies, because it is completely owned by you and it can also include your personal information in it.
 
I don't think you can do it if they don't allow it. If you succeed in improving, please let us know.
 
Creating a tool to auto-reply on Facebook Messenger can be complicated because Facebook is constantly updating and changing their API. It's difficult, but it can be done.
