Action Codes

Where can find a list of what the action codes mean? There is a brief description and a numerical value in the dashboard but I cannot find anything in detail about the code. I checked the Docs and the community but only a brief reference here;

I have an end user that appears to me to have scanned the QR code (Get Provision Token 74) but the dashboard shows “no data” under the devices heading. If there was a list somewhere with the explanation of what is intended by code 74 and all the others, I might have a better understanding of what is going on. I can confirm the device is connected to cellular via particle.

Thank you
