Hey folks,

is there any way to get the list of Contractors based created/modified datetime. Either adding parameter DateIssued or including header If-Modified-Since?

Both seems not working.

Thanks,

Hi,
Contractors endpoint should support if-modified-since and if-modified-before headers.

See more info here on date format to use and other info :
