How do I change facebook messenger bot webhook?

Question

I have successfully implemented a facebook bot. It's working fine. I was trying to change the webhook url now as I have to port it to a different server with a new domain.

There is an option to change the events but I could not find and option to change the webhook. How do I change it?

Answer 1

You can't edit the link directy from the "Messenger" product. On the left menu, after selecting your application, you have to click "+ add product" and add also webhooks. From webhooks then you can edit also messenger's webhook.

To edit the webhook, click on Edit Subscription button on the page. Make sure that the dropdown at the top has the option Page selected.

Ah at last I found it. Thanks for your answer. This should be the correct answer. – Impaste

When you click the webhooks as shown above, you will see a edit subscription button, click on it and you will be shown with screen where you can edit your parameters and then click verify and save – Thessalonians

How long does the change take to be in effect? I changed it and keep getting a reply from the old server. – Dylandylana

@FernandoAndré How long did it take? I've been waiting for 15h, and it's always linking with the old webhooks. – Prepense

@Prepense just put ur app in development mode and publish again..this works for me :) – Sletten

Nice gem!! Saved me a lot of time! – Postpone

I don't have 'Page' as an option. – Diagnostician

@Diagnostician : same here, it was there before, but disappeared somewhere last week. Changed it manually by doing a POST request to the subscriptions (More information here: developers.facebook.com/docs/graph-api/reference/app/…). Before you can do this, you need to generate an application access token first: developers.facebook.com/docs/facebook-login/… – Emmery

Answer 2

Besides setting from UI, you can also use subscriptions API to achieve this:

Docs: https://developers.facebook.com/docs/graph-api/reference/app/subscriptions

For example:

POST /v2.12/{app-id}/subscriptions HTTP/1.1
Host: graph.facebook.com

object=page&callback_url=http%3A%2F%2Fexample.com%2Fcallback%2F&fields=about%2C+picture&include_values=true&verify_token=thisisaverifystring

callback_url is what you want to change. Make sure you have correct field and verify_token setting too.

You can change webhook under "webhooks" in menu (picture).

Can't find that menu. Did someone find a solution to change webhook's url? – Engrain
