title: Thingspeak API security
body: <p>I'm looking at thingspeak which is very interesting. I signed up, created a channel and updated it. But the procedure to do this seems rather simple. One only has to post to the update URI with a key value like this: </p>
  
  <pre><code>curl --data "key=bla&amp;field1=1000" http://api.thingspeak.com/update
  </code></pre>
  
  <p>This seems rather insecure for me. One can use <code>https</code> of course. But does using TLS make it very secure?</p>
