Hello,

Using: http://yourserver/api/table.xml?content=sensortree&id=7788 I can retrieve exactly what I need to determine the ID of available sensors for a specific device.

I can not find a method that returns a simple "device not found" when supplied an invalid device id.

Ideally http://yourserver/api/table.xml?content=sensortree&id=bogus_id would return that.

Is there a simple, fast, supported way to do this?

Try the GetObjectsproperty function:

/api/getobjectproperty.htm?id=12345678

The reply is

<?xml version="1.0" encoding="UTF-8" ?> 
<prtg> 
<version>8.4.2.2381</version> 
<error>Sorry, the selected object cannot be used here or it does not exist.</error> 
</prtg>

Always check the ResponseUri from your request.

This will give you the "device not found" and other errors that might occur.

@Gerard Feijth - sadly that information does not appear in the return headers or return url for these particular requests (using cURL and php).

@Dirk Paessler - This works perfectly and is very fast, thank you.

Is it safer to use the strings:

'Sorry, the selected object cannot be used here or it does not exist.' === does not exist

and

'(Property not found)' === does exist

or do you recommend simply check against the existence of the <error> and <result> tags?
