Somehow i cant confirm Subscriptions for webhooks

katayayuci · October 27, 2020, 2:37pm

await request({
    url: 'https://api.twitch.tv/helix/webhooks/hub',
    method: 'POST',
    headers: {
        'Client-ID': "<clientid>",
        'Content-Type': 'application/json',
        'Authorization':'Bearer '+<token>
    },
    form: {
        'hub.callback': 'https://<ngrok things>.ngrok.io/twitch/webhook',
        'hub.mode': 'subscribe',
        'hub.topic': 'https://api.twitch.tv/helix/users/follows?first=1&to_id=<channelid>',
        'hub.lease_seconds': 864000,
        'hub.secret': "<secret>"
    },
    json: true
}, (err, res, body) => {
    if(err) console.log(err)

    //console.log(res)

This is my subscription request

app.get('/twitch/webhook', (req, res) => {
// confirms subscription
console.log(req.query["hub.challenge"]," challange code")
res.writeHead(200, {'Content-Type': 'text/plain'});
res.send(req.query['hub.challange']) 
});

Im sending the hub.challange back with text/plain header ( i try it without header too ) but when i check my subscriptions its “0” whats wrong also i cant get POST request’s from webhooks too

Consider moving from request, request is deprecated
You mis spelled challenge in your req.query call to res.send

Should be

res.send(req.query['hub.challenge'])

github.com

BarryCarlyon/twitch_misc/blob/master/webhooks/handlers/nodejs/receive.js#L63



// Routes
app
    .route('/')
    .get((req, res) => {
        console.log('Incoming Get request on /');
        // Twitch will send a verfiy to your handler
        // in order to verify that it can be access
        // we'll test if the call is from Twitch
        // the key contats a period so we are using array style access here
        if (req.query['hub.challenge']) {
            console.log('Got a challenge', req.query['hub.challenge']);
            // it's a challenge from Twitch
            // lets acknowledge it
            res.send(req.query['hub.challenge']);
        } else {
            console.log('Got a weird, no challenge');
            // normally won't get called
            // but we need to return something
            // someone direct called the URL for whatever reason
            // so we'll just OK and be done with it

You can just do

res.send(req.query['hub.challenge']);

No need to faff with headers

You won’t get any posts until you confirm the subscriptions
Did your code log the incoming get request and/or did ngrok log it? It’s possible that you hit the ngrok limits. So ngrok is ok for spot tests but best avoided after that

Yes its working rn thanks, and i dont understand why challenge works instead of “challange” cause im getting an token at console.log(req.query["hub.challenge"]," challange code")

console.log(req.query["hub.challenge"]," challange code")

Outputs the challenge from the query string then outputs the raw word of “challange” which is misspelt as well.

So the first part of the console log is correct.

You typoed the actual res.send
