Facebook messenger bot (webhook)

Question

I am trying to integrate facebook bot for my business page and followed this

Copied js code given to setup webhook and created a .js file... but when i tried to verify and save the message it showed was "The URL couldn't be validated. Response does not match challenge, expected value = '1227072936', received=' app.get('/webho...'".

I am .net developer and have no idea of javascript coding.

Can anyone suggest me where i am going wrong?

Answer 1

This is my code while verify web hook in java

i just create a serlvet with dopost method and then git the request parameters like below .. sure you have something like that in .net

        String token = req.getParameter("hub.verify_token");
        if (token != null && !token.equals("")) {
            resp.setContentType("text/html");

            if (token.equals("{verified_token}")) {
                String challenge = req.getParameter("hub.challenge");
                System.out.println("I am WebHock Verification -------->  ");

            }
        }

{verified_token} is the token i added while verify my webhook url

the webhook url in the image below replaced by my serlvet URL : I hope that help you
