Hello,

Trying to figure out how to add the WebDev module to my Ignition 8.1.20 instance running on Ubuntu Linux.

Regards.

In the gateway webpage, if you navigate to [Config \> System \> Modules](http://localhost/web/config/system.modules) than it will provide a page to upload the module.

You can also download the module at [[Current Ignition Release | Inductive Automation](https://inductiveautomation.com/downloads/ignition/8.1.20)] if you scroll down until you see WebDev.

Thank you, @kgamble. It wasn’t visible within the GW instance under Modules, but I was able to get it there by downloading from the IA page. The next hurdle is that it’s throwing an HTTP 402 error (basically a paywall) on the Webdev REST API call from Postman:  
HTTP ERROR 402 Payment Required  
URI: /system/webdev

Any idea how I can test out the API before purchasing?

If you’re getting a 402 it’s because your trial is expired. Reset it, you should be able to continue testing.
