MISSING_ARG_ACCESS_TOKEN for v3/shorten

[Libby Batten]

Hi there, 

While accessing the v3 Shorten API, I am getting a MISSING_ARG_ACCESS_TOKEN response no matter what I try. The access_token is correct, and the URL is encoded. I have confirmed this by accessing the api via a web link with my access token and a test URL. 

data: {"access_token":<access_token>,"longUrl":"http%3A%2F%2F<host><endodedparams>","format":"txt"}

bitly response: { "data": [ ], "status_code": 500, "status_txt": "MISSING_ARG_ACCESS_TOKEN" }

Does anything jump out in the code below that could be causing the error? Many thanks!

function shortenURL(accessToken : String, request : CurrentRequest) {

 var _timeout  = '3000';

 var host = 'api-ssl.bitly.com';

 var endpt = '/v3/shorten';

 var url : String = request.httpURL;

 var data : String = JSON.stringify({

 access_token : accessToken,

 longUrl : encodeURIComponent(url),

 format : 'txt'

 });

 var httpClient : HTTPClient = new HTTPClient();

 httpClient.setTimeout(_timeout);

 httpClient.open('GET', 'https://' + host + endpt);

 httpClient.send(data);

 if ( httpClient.statusCode != 200 ) {

 throw new Error('HTTP Communication error : Status code ' + httpClient.statusCode + ' - ' + httpClient.statusMessage);

 }

 var bitlyURL = JSON.parse(httpClient.text);

 return bitlyURL;

};

Hi Libby,

Looking at your code, you are turning your data from a hash into a JSON string and sending that to the endpoint. Our API does not accept JSON strings; instead, you should be turning the key-value pairs in your data blob into query parameters tacked on to the end of your request endpoint. I'm not conversant enough with JavaScript to know the idiomatic way of doing so, but your code should have the equivalent of this:

httpClient.open('GET', 'https://api-ssl.bitly.com/v3/shorten?access_token=XXXXX&longUrl=http%3A%2F%2FYYYYYYY&format=txt');

None of our APIs accept JSON, they all require percent-encoded query parameters. Let us know if you have further questions.

Hi Peter, thank you for your help. 

With the parameters appended using the open method only, there is no response,

[ allResponseHeaders=null, errorText=null, statusCode=0, statusMessage=null, text=null

httpClient.open('GET', 'https://api-ssl.bitly.com/v3/shorten?access_token=' + accessToken +'&longUrl=' +encodeURIComponent(url) + '&format=txt');

Using the send method I'm still getting the 

bitly response: { "data": [ ], "status_code": 500, "status_txt": "MISSING_ARG_ACCESS_TOKEN" }

var httpClient : HTTPClient = new HTTPClient();
 httpClient.setTimeout(_timeout);

 httpClient.open('GET', 'https://api-ssl.bitly.com/v3/shorten');
 httpClient.send('?access_token=' + accessToken +'&longUrl=' +encodeURIComponent(url) + '&format=txt');

Any more ideas?

Hi Libby,

Unfortunately, I'm not proficient with JavaScript, so I'm not going to be able to be much help to you in figuring out the specific syntax you need to accomplish an HTTP GET request. But the API URL example I gave you should be enough, along with the normal language documentation, to get you started in the right direction. I can point to some examples in Python, if that helps at all:  https://github.com/tpherndon/bitly_api_examples/blob/master/link_details.py

Hi Peter,

I was able to get this to work with your suggestion, the missing piece was httpClient.send() so thank you very much for your help.
