title: Node Red HTTP POST for every JSON object (loop)
body: <p>I'm working in Node Red and I need to understand how to loop JSON object and, for each JSON object, make a HTTP request towards another endpoint.</p>
  
  <p>In other words: here's the use case I will need to represent.<br>
  Node Red makes a HTTP post to get all devices.<br>
  All devices are returned in a JSON, with several information and a DEVICE_ID.<br>
  For every device ID, Node Red has to make another HTTP request passing the above id, to get all the resources for that device.</p>
  
  <p>I'm in trouble since I expected Node Red to have a dedicated block for loops, but is not like that. So how can I make a workaround?</p>
  
  <p>If I use the "function" block, and I type there the code to make my loop, how to "come back" to the flow view, using Http blocks? Thank you!</p>
