I'm facing an issue with the Facebook Conversation Routing as described in their documentation. According to the documentation, if a page agent responds to a message in a conversation not currently controlled by the inbox, the inbox should take control of the conversation. However, this is not happening in my case. documentation

Note: Although it doesn't work for Facebook conversation, it does work for Instagram conversations (i.e. the instagram conversation is assigned to the Inbox if replied through the Inbox app)

Current configuration: In my facebook page > Settings > Page Setup > Messenger Conversation Routing> Default App is set to my chatbot app In Page Setup > Advanced Messaging, I've tried both leaving the 'Primary Receiver for Handover Protocol' field empty and setting my app as the primary receiver

Steps to reproduce the issue:

A user sends a message to our Facebook page. The chatbot, which initially controls the conversation, receives and responds the message. I then respond to the message directly through the Inbox (https://business.facebook.com/latest/inbox/). Expected behaviour: According to the documentation, once I respond through the Inbox, control of the conversation should transfer from the chatbot app to the Inbox.

Actual behaviour: Despite responding through the Inbox, the conversation remains assigned to the chatbot app. Therefore if the user responds my chatbot is triggered. I also confirmed this by calling the thread_owner endpoint, which still shows the chatbot as the owner.

Troubleshooting steps taken:

Double-checked the app and page settings to ensure they align with the expected routing behaviour. I can confirm since Conversation Routing is enabled, I do not receive message_handover webhooks once the conversation is closed. I believe this is expected behaviour as also noted in the documentation documentation

Question: Has anyone else encountered this issue? Are there specific settings or conditions that might prevent the expected transfer of conversation control from the chatbot to the Inbox? Any insights or suggestions on how to resolve this would be greatly appreciated.

I have a problem with my nodejs code and the connection to the official whatsapp business api.

The bot connects the webhook correctly, the messages arrive to the server correctly but the code I have implemented to make it respond is not being effective, I checked the code from top to bottom but I can't find the fault.

I leave you the codes so you have more context:

whatsappController.js:

const fs = require("fs"); const myConsole = new console.Console(fs.createWriteStream("./logs.txt")); const whatsappService = require("../services/whatsappService") const VerifyToken = (req, res) => {     try {         var accessToken = "456E7GR****************************";         var token = req.query["hub.verify_token"];         var challenge = req.query["hub.challenge"];         if(challenge != null && token != null && token == accessToken){             res.send(challenge);         }         else{             res.status(400).send();         }     } catch(e) {         res.status(400).send();     } } const ReceivedMessage = (req, res) => {     try {         var entry = (req.body["entry"])[0];         var changes = (entry["changes"])[0];         var value = changes["value"];         var messageObject = value["messages"];         if(typeof messageObject != "undefined"){             var messages = messageObject[0];             var text = GetTextUser(messages);             var number = messages["from"];             myConsole.log("Message: " + text + " from: " + number);             whatsappService.SendMessageWhatsApp("The user say: " + text, number);                          myConsole.log(messages);             myConsole.log(messageObject);         }         res.send("EVENT_RECEIVED");     }catch(e) {         myConsole.log(e);         res.send("EVENT_RECEIVED");     } } function GetTextUser(messages){     var text = "";     var typeMessage = messages["type"];     if(typeMessage == "text"){         text = (messages["text"])["body"];     }     else if(typeMessage == "interactive"){         var interactiveObject = messages["interactive"];         var typeInteractive = interactiveObject["type"];         if(typeInteractive == "button_reply"){             text = (interactiveObject["button_reply"])["title"];         }         else if(typeInteractive == "list_reply"){             text = (interactiveObject["list_reply"])["title"];         }else{             myConsole.log("sin mensaje");         }     }else{         myConsole.log("sin mensaje");     }     return text; } module.exports = {     VerifyToken,     ReceivedMessage } 

The second file is whatsappService which I make the connection with the api using the token and I also send the format of the message I want to send when I receive a hello for example...

const https = require("https"); function SendMessageWhatsApp(textResponse, number){     const data = JSON.stringify({         "messaging_product": "whatsapp",             "recipient_type": "individual",         "to": number,         "type": "text",         "text": {             "preview_url": false,             "body": textResponse         }     });     const options = {         host:"graph.facebook.com",         path:"/v15.0/1119744*************/messages",         method:"POST",         body:data,         headers: {             "Content-Type":"application/json",             Authorization:"Bearer EAAWNbICfuWEBAK5ObPbD******************************************************"         }     };     const req = https.request(options, res => {         res.on("data", d=> {             process.stdout.write(d);         });     });     req.on("error", error => {         console.error(error);     });     req.write(data);     req.end(); } module.exports = {     SendMessageWhatsApp }; 

Then I declare the routes for the get (to check token) and post (to receive and reply to messages) methods:

const expres = require("express"); const router = expres.Router(); const whatsappController = require("../controllers/whatsappControllers"); router .get("/", whatsappController.VerifyToken) .post("/", whatsappController.ReceivedMessage) module.exports = router; 

Last but not least the index file for the code to run correctly:

const express = require("express"); const apiRoute = require("./routes/routes"); const app = express(); const PORT = process.env.PORT || 3000 app.use(express.json()); app.use("/whatsapp", apiRoute); app.listen(PORT, () => (console.log("El puerto es: " + PORT))); 

I should clarify that I did the tests with Postman and they were all successful, it responds and receives messages correctly, finally I did the tests by uploading the bot to the Azure service and it works without problem until it has to answer/replicate the user's message.

The bot is not responding to the user when he talks to it but everything arrives correctly to the server and it processes it with a 200 response. I attach the evidence that there is no problem in the reception.

Finally I must say that in the meta platform I have everything configured as specified by the same platform, I have already configured the api to answer the messages through the webhooks and everything is correct, I just can't get the bot to answer correctly.

The bot is hosted in the Azure service.
