Error Reference

When a problem occurs during a request it maybe necessary to return an invalid response. A Error xml page is returned when an api customer submits a request that cannot be completed for any reason.

Lets generate an error by performing a query on a group without our id. This is what we will send to the server

http://demosrch.publicdata.com/pdquery.php?o=grp_master12390&dlnumber=DEMO&disp=XML


Here is the response from that request.


As you can tell the error pages are pretty simple. There are only a couple of things to note.

pddata - see the common nodes section for a description.
Attributes:
type - In this case the type returned is 'error'.
message - This node has human readable information about what went wrong.
