  An Onshape app requires something called oauth to allow your website to talk to their servers. Here's the oauth code used on my new site. To see this work, cut the url address below and paste it into your browser.
  
  1. It starts with the web address and in my case its:
  https://rndengineering.com/pro/
  
  
  2. There's no parameters sent in this address so I capture this and send the user to onshape. Here's the code that checks for parameters and re-locates to onshape:
   
  

  //handle oauth code, no code?, go get it<br>if (!$_REQUEST["code"])&nbsp;&nbsp; <br>echo '<script>location = "https://oauth.onshape.com/oauth/authorize?response_type=code&client_id=DZ3JRO3ECFWZY7ZVY%3D";</script>';

  
  
  3. This sends the user off to Onshape so they can allow the user to sign in. Upon success, they'll send the user back to my site base on a url return address I registered in the app store. Here's the updated address Onshape sends back:
  
  https://rndengineering.com/pro/?code=vfmAcpHiNkFRkl
  
  The url address above won't work if you copy it into a browser, it's a deadend and goes nowhere, timed out. Notice that Onshape adds a code to the url.
  
  
  4. With a code returned from Onshape, I request a token from Onshape:
  

  <div>//have code so process<br></div><div>$token="curl -X POST -H \"Content-Type:application/x-www-form-urlencoded\" -d \"grant_type=authorization_code&code=$_REQUEST["code"]&client_id=DZ3JROH7SNRVW2Y7ZVY%3D&client_secret=C2A2VUGAHV4H2XM5SNEC5VQ%3D%3D%3D%3D\"&nbsp; \"https://oauth.onshape.com/oauth/token\" ";<br></div>

  
  The ultimate piece of information, the reason for all this interaction is inside $token.
  
  5. Grab the 'access_token'. It's needed for all subsequent calls to Onshape servers and it only lasts for 60 minutes. Get the access token:
  
  

  //yeah just what I need<br>$token['access_token']

  
  
  Here's a video link to my latest code:

  @billy2
  
  Thanks for the app! Looks really useful.  Lack of display states & better property management has been a big deal for adoption of OS by my engineers.  Will look forward to your next releases and in meantime I am going to start testing it out.

  Did this post once have code included?  Sounds like yes but it's vanished.

  I don't think the code was uploaded.
  
  I have the steps in php & nodejs. There's plenty of python examples. Have you checked out the github repository for onshape?
  
  My code isn't commented and probably would do more harm than good if I posted it.
  
  oauth is a simple dance between your client, your server & onshape.
  
  Look at the github and if that doesn't work, then I'll compose a video showing how it's done. That might be best.
