Using the Known API

2 min read

I was looking for a way to import my twitter favourites. First I was thinking about writing a plugin that checks the twitter api for new likes, but no one ain't no time for that.

So reading about IFTTT again, I wanted to give a try as the maker channel seems to fit as it let's you make web request to a publicly accessible URL. No luck with the Known API, it needs some custom http headers.

So I wrote a quick and dirty request forwarder : KnownApiForward. It takes the request from ifttt and passes it to the known api.

Thanks to Marcus Povey who gave me some good tips on how to start with writing an api for Known, could quickly put some code together.

The Known documentation is still a bit poor and one has to get the pieces together if you're not familiar with it.

What you need is :

your endpoint (your_known/action/edit in my case for a status https://nxd4n.nixekinder.be/status/edit)

your api key (account settings -> tools).

Calculate the token :

$token = base64_encode(hash_hmac('sha256',$known['action'] ,$known['known_api_key'] , true));

 

 Headers for the curl call :

$known['headers'] =   array('Accept: application/json',
                                     'X-KNOWN-USERNAME: ' . $known['username'],
                                     'X-KNOWN-SIGNATURE: ' .$known['token'],
                                     'Content-Type: application/json', 
                                     'Content-Length: ' . strlen($known['status']));



 And the curl options :

 

curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookiefile");
curl_setopt($ch, CURLOPT_URL,"YOUR_KNOWN_SITE_URL".$known['action']);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $known['status']);
curl_setopt($ch, CURLOPT_HTTPHEADER, $known['headers']); 

In IFTT, create a recipe with the Maker Channel. Provide the script's url and put a json formatted text in the body field :
