title: How to save and recieve String in thingspeak.com?
body: <p>I know how to save data like(<code>1,2,2.3,65.2</code>).</p>
  
  <p>I was wondering if its possible to save and retrieve data like(<code>'AP09BN7886'</code>)(<code>String</code>) in thingspeak.com?<br>
  I am sending data to thingspeak.com via esp8266 connected to my arduino UNO using AT commands.</p>
