IFS REST API call not working - TimmanJobTranses

Hi,

Our IFS environment is currently on UPD10

I am unable to get the TimmanJobTranses API REST ‘update’ action to work in post man, I keep on receiving this “Illegal operation” error message. see image below.

I have already tried the following

1. Remove header parameter ‘If-Match’

I have got in contact with another IFS application user they are currently on UPD11 and the TimmanJobTranses API REST ‘update’ action is currently working in there environment.

Is this a fixed issue in UPD11 and above?
