Building webhooks with NodeJS

[pazpurua]

We have an endpoint for the webhhok. But I dont know how to get the crc

app.post(’/webhook/twitter’, function (request, response) {
var fecha = new Date()
//var respuesta = { “fecha”: fecha.toString(), “nombre”: “prueba post en webhook/twitter” }
var respuesta = { “status”: 200, “data”: “Webhook URL ok” }

//var respuesta=request.body
response.end(300,JSON.stringify(respuesta));
//azurefunctions.postWEBHOOK(respuesta, function (err, flag) {
//   // response.end(JSON.stringify(respuesta));
//    response.end(respuesta);
//})

});

Perhaps you coul explain

Hello pazpurua,

Please review guide of security and that you have to implement on you webhook get request.
Below is my code where I got verified my webhook.

var crypto = require(‘crypto’);
var hmac = crypto.createHmac(‘sha256’, _environment.env.config.twitter.consumer_secret);
app.get(’/twitter/webhook’, function (req, res) {
var reqQuery = req.query;
hmac.update(reqQuery.crc_token);
var sha256_hash_digest = hmac.digest(‘base64’);
res.status(200).send({ “response_token”: “sha256=” + sha256_hash_digest });
});

Hello. I have been in other matters and I am back.
We have included in our server. https://github.com/twitterdev/twitter-webhook-boilerplate-node/blob/master/example_scripts/webhook_management/update-wehbhook-url.js

And when we execute the createConfig() we obtain the following message: {“errors”:[{“code”:32,“message”:“Could not authenticate you.”}]}

We have the get and post for the webhhok url.

Yours Pedro

I have noticed that the getConfig() already says that {“code”:32,“message”:“Could not authenticate you.”

function getConfig() {
// request options
console.log(“getConfig()”)
var request_options = {
url: ‘https://api.twitter.com/1.1/account_activity/webhooks.json’,
oauth: twitter_oauth
}

// GET request to retreive webhook config
request.get(request_options, function (error, response, body) {
    var configs = JSON.parse(body)

    if (configs.length > 0) {
        current_config = configs[0]
        console.log(current_config)
        removeSubscription(current_config.id);
    } else {
        console.log('App does not have a webhook config.')
        createConfig()
    }
})

}
