Failed to create subscription: WebHook responds with incorrect HTTP status. HTTP status is 404

Question

I have an unbuntu server running apache with virtual directories. I’m getting the following error when I attempt to register a webhook: Failed to create subscription: WebHook responds with incorrect HTTP status. HTTP status is 404.

The code that is rendering this error is:

async function createSubscription() {
    try {
        let response = await platform.post('/restapi/v1.0/subscription', {
            eventFilters: F
                "/restapi/v1.0/account/~/extension/~/telephony/sessions"
            ],
            deliveryMode: {
                transportType: "WebHook",
                address: process.env.WEBHOOK_URL
            }
        });
        console.log("Subscription created:", response.data);
    } catch (error) {
        console.error("Failed to create subscription:", error.message);
    }
}

You should make sure that your webhook endpoint is publicly accessible. You must also make sure that you capture the ‘validation-token’ and return it in the header within 3 secs. In Node JS code, it looks like this.

if(req.headers.hasOwnProperty("validation-token")) {
   res.setHeader('Validation-Token', req.headersd'validation-token']);
   res.statusCode = 200;
   res.end();
}else{
   // read the event data
}
