how to withdraw an absence in fusion HCM via REST API?

Hi,

has anyone ever looked at the requirement to withdraw an absence via a web service from Oracle HCM, REST or SOAP?

This is probably an edge case scenario, but the premise here is that an employee has submitted an absence request and its approved... but we now need to with draw via some Integration, ideally calling a REST endpoint (if one exists)?

effectively deleting a previously approved absence request...

thanks

Mark
