not able to register in facebook webhook

[rcchit]

Trying to register facebook webhook and keep getting error listed below .BTW I changed in index.js from FB_PAGE_ACCESS_TOKEN to PAGE_ACCESS_TOKEN

"The URL couldn't be validated. Response does not match challenge, expected value="492837124", received="hello world i am a..."

I created these config on heroku
PAGE_ACCESS_TOKEN
VERIFY_TOKEN

@rcchit what is the URL you are using?

[Komsomol]

I had the same issue. You need to paste in the url with /webhook.

https://this-app-68903.herokuapp.com/webhook/

Since this is the sub-dir in the code for FB verification

app.get('/webhook/', function (req, res) {

@Komsomol I had the same issue. After adding /webhook/ everything worked.

I am getting the below error, when trying to setup the webhook. How do we add configurations to heroku? I do not have any prior knowledge in cloud deployment. Please help.

The URL couldn't be validated. Callback verification failed with the following errors: HTTP Status Code = 503; HTTP Message = Service Unavailable

I get a similar error
Adding /webhook/ doesn't really help either

I've tried even changing the Procfile to a different version (mentioned in another issue) and it fails still

[kostimarko]

@sunnyMiglani are you getting a 503 error?

[codename-47]

@sunnyMiglani We need to provide start script to "start": "node index.js" in package.json file. Hope that works.

@kostimarko I'm getting a 502 "bad gateway" error

@codename-47 I've tried adding that, still receive the same error

[kostimarko]

@sunnyMiglani have you tried running it with out a heroku config?

@codename-47 on adding configurations

Generate a token from this site and save the token somewhere:

To add configurations to heroku, type this command into the terminal while in your working directory.
heroku config:set FB_PAGE_ACCESS_TOKEN=fake-access-token-dhsa09uji4mlkasdfsd

You can then access the token in your index.js file as follows:

I am facing similar problem here is my issue,

The URL couldn't be validated. Response does not match challenge, expected value="1060150785", received=""1060150785""

[abhilashrao]

@F-Makhokha check for index.js and add https://YOUR-APP.herokuapp.com/webhook/
your token would be: my_voice_is_my_password_verify_me as mentioned in index.js

Hello, any updates about that issue ? Thanks in advance

Deploy the Heroku app first using git and then you should register the facebook webhook.

Had the same issue, but turns out I was using the wrong URL. Use the URL that comes out in the build logs
