I'm trying to add a users identity to a channel using the REST API using instructions here: https://www.twilio.com/docs/api/ip-messaging/rest/members#action-create
I'm posting to the /Channels/channelId/Members endpoint - I'm certain my request is structured correctly.
I get an error back from Twilio IP Messaging saying:
{"code": 50200, "message": "User not found", "more_info": "https://www.twilio.com/docs/errors/50200", "status": 400}
My understanding was that we can provide our own identity when we want to add someone to a Channel. How can I 'register' the user (with an email) before adding them to the Channel?
EDIT - The code:
var _getRequestBaseUrl = function() {
return 'https://' +
process.env.TWILIO_ACCOUNT_SID + ':' +
process.env.TWILIO_AUTH_TOKEN + '#' +
TWILIO_BASE + 'Services/' +
process.env.TWILIO_IPM_SERVICE_SID + '/';
};
var addMemberToChannel = function(memberIdentity, channelId) {
var options = {
url: _getRequestBaseUrl() + 'Channels/' + channelId + '/Members',
method: 'POST',
headers: {
'content-type': 'application/x-www-form-urlencoded',
},
form: {
Identity: memberIdentity,
},
};
request(options, function(error, response, body) {
if (error) {
// Getting the error here
}
// do stuff with response.
});
};
addMemberToChannel('test1#example.com', <validChannelId>);
Twilio developer evangelist here.
In order to add a user to be a member of a channel, you do indeed need to register them first. Check out the documentation for creating a user in IP Messaging.
With your code you'd need a function like:
var createUser = function(memberIdentity) {
var options = {
url: _getRequestBaseUrl() + 'Users',
method:'POST',
headers: {
'content-type': 'application/x-www-form-urlencoded',
},
form: {
Identity: memberIdentity,
}
};
request(options, function(error, response, body) {
if (error) {
// User couldn't be created
}
// do stuff with user.
});
}
Could I also suggest you take a look at the Twilio helper library for Node.js. It handles the creation of URLs like you're doing for you. The code looks cleaner too, you can create a user with the helper library like this:
var accountSid = 'ACCOUNT_SID';
var authToken = 'AUTH_TOKEN';
var IpMessagingClient = require('twilio').IpMessagingClient;
var client = new IpMessagingClient(accountSid, authToken);
var service = client.services('SERVICE_SID');
service.users.create({
identity: 'IDENTITY'
}).then(function(response) {
console.log(response);
}).fail(function(error) {
console.log(error);
});
Let me know if this helps at all.
hi I am new to elgg REST API.
I want to login and add post to wire for that I have method=wire.save_post
I learned from Google that api auth and user auth must be given in request header how?
I am doing a ajax for adding post to wire :
$("#post_text").submit(function() {
$.ajax({
type:"POST",
url:"http://elgg.amusedcloud.com/services/api/rest/json/?",
data:{ method:'wire.save_post', text : text_val, access : 'public', wireMethod : 'site', username : uname },
dataType:"json",
success: function(data) {
}
});
});
Normally an ajax call to the elgg webservice you are referring to should look something like this. Note that the api_key and auth_token are part of the request URL.
$("#post_text").submit(function() {
$.ajax({
type:"POST",
url:"http://elgg.amusedcloud.com/services/api/rest/json/?method=wire.save_post&api_key=1140321cb56c71710c38feefdf72bc462938f59f&auth_token=df123dfgg455666",
data:{
text : text_val,
access : 'public',
wireMethod : 'site',
username : uname
},
dataType:"json",
success: function(data) {
}
});
});
You didn't mention this but, when you say
... I learned from Google that api auth and user auth must be given in request header
is this in the context of using OAuth as an authentication mechanism? In which case, you will have to use the HTTP header Authorization to send the hash and signature. The above call would then be like this.
$("#post_text").submit(function() {
$.ajax({
type:"POST",
url:"http://elgg.amusedcloud.com/services/api/rest/json/?method=wire.save_post&auth_token=df123dfgg455666",
data:{
text : text_val,
access : 'public',
wireMethod : 'site',
username : uname
},
beforeSend: function(xhr){
xhr.setRequestHeader('X-Test-Header', 'test-value');
},
dataType:"json",
success: function(data) {
}
});
});
Note the changes in the url and addition of beforeSend property to the ajax object.

I'm developing a simple node/express/jade website that fetch all the public feeds of a Facebook Page.
I create an application from wich i get client_id (APP_ID) and client_secret (APP_SECRET).
My code works, and it's okay but i wonder if this is the correct way of handling this need.
Here is the code:
var https = require('https'),
concat = require('concat-stream'),
async = require('async');
function FacebookPage(pageId) {
if (!(this instanceof FacebookPage))
return new FacebookPage(pageId);
this.pageId = pageId;
}
FacebookPage.prototype.getPublicFeeds = function (callback) {
var pageId = this.pageId;
async.waterfall([
function (done) {
var params = {
hostname: 'graph.facebook.com',
port: 443,
path: '/oauth/access_token?client_id=MY_CLIENT_ID&' +
'client_secret=MY_CLIENT_SECRET&grant_type=client_credentials',
method: 'GET'
};
https.get(params, function (response) {
//response is a stream so it is an EventEmitter
response.setEncoding("utf8");
//More compact
response.pipe(concat(function (data) {
done(null, data);
}));
response.on("error", done);
});
},
function (access_token, done) {
var params = {
hostname: 'graph.facebook.com',
port: 443,
path: '/v2.0/' + pageId + '/feed?' + access_token,
method: 'GET'
};
https.get(params, function (response) {
//response is a stream so it is an EventEmitter
response.setEncoding("utf8");
//More compact
response.pipe(concat(function (data) {
callback(null, JSON.parse(data));
}));
response.on("error", callback);
});
}]);
};
module.exports = FacebookPage;
EDIT: thank to #Tobi I can delete the part of getting the access_token by putting access_token=app_id|app_secret as explained here:
Not sure why you'd want to include to OAuth stuff (which I think can't work because you don't exchange the code for an actual access token if I understand this correctly)...
According to https://developers.facebook.com/docs/graph-api/reference/v2.0/page/feed/ you need an access token ... to view publicly shared posts., this means you can also use an app access token in the form of app_id|app_secret.
You can then use the
GET /{page_id}/feed
endpoint by passing the access_token paramenter with your app access token. I'd also recommend to use the NPM modules request or restler, these make the HTTP handling much easier.
I'm trying to get XML response from a secure https URL using Jquery AJAX call...
I'm getting the following error. Can anyone help me with the issue?
Unauthorized user
Here is my code
$.ajax({
type : "GET",
url : url + "?" + params,
error : function(jqxhr, status, error)
{
alert(status +"....."+error);
},
success : function(data, textStatus, jqxhr) {
var xmlDoc = jqxhr.responseText;
alert(xmlDoc);
}
});
Definitely need more details, but if you're sending a request to a secure url, you likely need to pass some kind of value to show you're logged in or some-such, like a cookie value. To pass a value, you may need to use the headers option:
$.ajax({
type : "GET",
url : url + "?" + params,
headers : {"COOKIE", "userID=h3j5o273h4"},
error : function(jqxhr, status, error)
{
alert(status +"....."+error);
},
success : function(data, textStatus, jqxhr) {
var xmlDoc = jqxhr.responseText;
alert(xmlDoc);
}
});
In Node.js, other than using child process to make CURL call, is there a way to make CURL call to remote server REST API and get the return data?
I also need to set up the request header to the remote REST call, and also query string as well in GET (or POST).
I find this one: http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs
but it doesn't show any way to POST query string.
Look at http.request
var options = {
host: url,
port: 80,
path: '/resource?id=foo&bar=baz',
method: 'POST'
};
http.request(options, function(res) {
console.log('STATUS: ' + res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('BODY: ' + chunk);
});
}).end();
How about using Request — Simplified HTTP client.
Edit February 2020: Request has been deprecated so you probably shouldn't use it any more.
Here's a GET:
var request = require('request');
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode === 200) {
console.log(body) // Print the google web page.
}
})
OP also wanted a POST:
request.post('http://service.com/upload', {form:{key:'value'}})
I use node-fetch because it uses the familiar (if you are a web developer) fetch() API. fetch() is the new way to make arbitrary HTTP requests from the browser.
Yes I know this is a node js question, but don't we want to reduce the number of API's developers have to memorize and understand, and improve re-useability of our javascript code? Fetch is a standard so how about we converge on that?
The other nice thing about fetch() is that it returns a javascript Promise, so you can write async code like this:
let fetch = require('node-fetch');
fetch('http://localhost', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: '{}'
}).then(response => {
return response.json();
}).catch(err => {console.log(err);});
Fetch superseeds XMLHTTPRequest. Here's some more info.
Look at http://isolasoftware.it/2012/05/28/call-rest-api-with-node-js/
var https = require('https');

Axios
An example (axios_example.js) using Axios in Node.js:
const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;
app.get('/search', function(req, res) {
let query = req.query.queryStr;
let url = `https://your.service.org?query=${query}`;
axios({
method:'get',
url,
auth: {
username: 'the_username',
password: 'the_password'
}
})
.then(function (response) {
res.send(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});
});
var server = app.listen(port);
Be sure in your project directory you do:
npm init
npm install express
npm install axios
node axios_example.js
You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx
Similarly you can do post, such as:
axios({
method: 'post',
url: 'https://your.service.org/user/12345',
data: {
firstName: 'Fred',
lastName: 'Flintstone'
}
});
SuperAgent
Similarly you can use SuperAgent.
superagent.get('https://your.service.org?query=xxxx')
.end((err, response) => {
if (err) { return console.log(err); }
res.send(JSON.stringify(response.body));
});
And if you want to do basic authentication:
superagent.get('https://your.service.org?query=xxxx')
.auth('the_username', 'the_password')
.end((err, response) => {
if (err) { return console.log(err); }
res.send(JSON.stringify(response.body));
});
Ref:
https://github.com/axios/axios
https://www.twilio.com/blog/2017/08/http-requests-in-node-js.html
I have been using restler for making webservices call, works like charm and is pretty neat.
To use latest Async/Await features
https://www.npmjs.com/package/request-promise-native
npm install --save request
npm install --save request-promise-native
//code
async function getData (){
try{
var rp = require ('request-promise-native');
var options = {
uri:'https://reqres.in/api/users/2',
json:true
};
var response = await rp(options);
return response;
}catch(error){
throw error;
}
}
try{
console.log(getData());
}catch(error){
console.log(error);
}
Warning: As of Feb 11th 2020, request is fully deprecated.
One another example - you need to install request module for that
var request = require('request');
function get_trustyou(trust_you_id, callback) {
var options = {
uri : 'https://api.trustyou.com/hotels/'+trust_you_id+'/seal.json',
method : 'GET'
};
var res = '';
request(options, function (error, response, body) {
if (!error && response.statusCode == 200) {
res = body;
}
else {
res = 'Not Found';
}
callback(res);
});
}
get_trustyou("674fa44c-1fbd-4275-aa72-a20f262372cd", function(resp){
console.log(resp);
});
const http = require('http');
const url = process.argv[2];
http.get(url, function(response) {
let finalData = "";
response.on("data", function (data) {
finalData += data.toString();
});
response.on("end", function() {
console.log(finalData.length);
console.log(finalData.toString());
});
});
I didn't find any with cURL so I wrote a wrapper around node-libcurl and can be found at https://www.npmjs.com/package/vps-rest-client.
To make a POST is like so:
var host = 'https://api.budgetvm.com/v2/dns/record';
var key = 'some___key';
var domain_id = 'some___id';
var rest = require('vps-rest-client');
var client = rest.createClient(key, {
verbose: false
});
var post = {
domain: domain_id,
record: 'test.example.net',
type: 'A',
content: '111.111.111.111'
};
client.post(host, post).then(function(resp) {
console.info(resp);
if (resp.success === true) {
// some action
}
client.close();
}).catch((err) => console.info(err));
If you have Node.js 4.4+, take a look at reqclient, it allows you to make calls and log the requests in cURL style, so you can easily check and reproduce the calls outside the application.
Returns Promise objects instead of pass simple callbacks, so you can handle the result in a more "fashion" way, chain the result easily, and handle errors in a standard way. Also removes a lot of boilerplate configurations on each request: base URL, time out, content type format, default headers, parameters and query binding in the URL, and basic cache features.
This is an example of how to initialize it, make a call and log the operation with curl style:
var RequestClient = require("reqclient").RequestClient;
var client = new RequestClient({
baseUrl:"http://baseurl.com/api/", debugRequest:true, debugResponse:true});
client.post("client/orders", {"client": 1234, "ref_id": "A987"},{"x-token": "AFF01XX"});
This will log in the console...
[Requesting client/orders]-> -X POST http://baseurl.com/api/client/orders -d '{"client": 1234, "ref_id": "A987"}' -H '{"x-token": "AFF01XX"}' -H Content-Type:application/json
And when the response is returned ...
[Response client/orders]<- Status 200 - {"orderId": 1320934}
This is an example of how to handle the response with the promise object:
client.get("reports/clients")
.then(function(response) {
// Do something with the result
}).catch(console.error); // In case of error ...
Of course, it can be installed with: npm install reqclient.
You can use curlrequest to easily set what time of request you want to do... you can even set headers in the options to "fake" a browser call.
Warning: As of Feb 11th 2020, request is fully deprecated.
If you implement with form-data, for more info (https://tanaikech.github.io/2017/07/27/multipart-post-request-using-node.js):
var fs = require('fs');
var request = require('request');
request.post({
url: 'https://slack.com/api/files.upload',
formData: {
file: fs.createReadStream('sample.zip'),
token: '### access token ###',
filetype: 'zip',
filename: 'samplefilename',
channels: 'sample',
title: 'sampletitle',
},
}, function (error, response, body) {
console.log(body);
});
I found superagent to be really useful,
it is very simple
for example
const superagent=require('superagent')
superagent
.get('google.com')
.set('Authorization','Authorization object')
.set('Accept','application/json')
Update from 2022:
from node.js version v18 on you can use the globally available fetch API (see https://nodejs.org/en/blog/announcements/v18-release-announce/)
There is also an example usage included on their announcement page:
const res = await fetch('https://nodejs.org/api/documentation.json');
if (res.ok) {
const data = await res.json();
console.log(data);
}
