What about changing the attribute of an item? Not too difficult. You'll need the ID of the device you want to change, along with the attribute name from the database . You can see these and an access token.
Access tokens are generated with every request type. You will need a token when submitting a POST or PATCH request. RUn another query (a GET is fine, even if no items are returned) and parse the JSON reqponse for meta → access_token. Include this in your request body as below.
Attribute names are visible in the application by going to menu → Admin → Database → List Tables and clicking on the "system" table. Let's change the description for our device with ID 14.
You'll need to create a JSON object and assign it to the "data" item to do this. It's not too difficult. Your JSON object should look like below (formatted and indented for easy reading).

"id": "14",
"type": "devices",
"attributes": {
"description": "My New Description"
}

What about running a query? What's the HTTP verb used to EXECUTE something? There is none 
But we'll make do by supplying /execute after the ID. So to execute a query, make a GET request to http://192.168.84.4/omk/open-audit/queries/1/execute. To execute a discovery, task or baseline, use the same format - ID/execute.
If we want to create a new item, use a http verb of POST^ and include an access token. An access token is generated with every request (except logon) and any of the last 20 (by default, settable in the configuration) will be accepted. You should always aim to use the last access token issued.
Remember we always receive the result in JSON as that is in our request header. We could receive it as HTML is we want - just remove that header item. Maybe more useful is a CSV output. Remove the Accept header and change the URL for a GET to http://192.168.84.4/omk/open-audit/queries/1/execute?format=csv. Done - CSV output you can copy and paste into Excel.

That makes for a simple and easy way to test the Open-AudIT API.
