Tag Creation through PIWebAPI

I'm struggling to understand how to properly create tags using PIWebAPI. I can create them fine, using POST to /points but I can only set basic attributes such as point type and class. How do I update the other attributes such as instrument tag or the location values?

i referenced the update action https://docs.aveva.com/bundle/pi-web-api-reference/page/help/controllers/point/actions/update.html but some fields are not allowed?? How do i update these through the API?

thanks for any help you can provide.

Hello aegelhof1 ,
the limitation you ran into is documented. Please allow me to quote the documentation page you already linked.
The following PI Point attributes can be updated: Name, Descriptor, EngineeringUnits, Step, and DisplayDigits.
Have you tried Point UpdateAttributeValue?

Hello Gregor.Beck I'm aware of the documentation but I was looking for a way around it. Just to see if anybody else had any ideas, I have not tried the udpateattributevalue method, I'll see if that will work.

Its frustrating that the API is not fully featured, it makes it extremely difficult to to use. I want to migrate many of my legacy SDK apps to PIWEBAPI but there are just far too many limitations to do so..

Thank you for the reply.
