Using HTTP POST to Update via PI Web API

Hi All,

 

I am attempting to use the PI Web API to update an AF attribute, but I have a REST client that does not natively support the PATCH method.

 

I understand there is a header that can be added to override the method from POST to PATCH, but this doesn't appear to be working.

 

I've tried both "X-HTTP-Method-Override: PATCH" and "X-PIWEBAPI-HTTP-METHOD: PATCH".

 

Any suggestions?

 

OR is there a way to update using CreateAttribute that updates the specified attribute instead of creating a new child?

 

Thanks!

Mike
