Query PI AF by attribute name using the PI Web API

Hello kevinum​ ,

Please refer to the example provided in the reference manual for Attribute GetAttributesQuery. The Search Query Syntax isn't trivial and requires some exercising. Please follow the links to get better guidance. GetAttributes is intended to search Attributes for an Element and yes, it is possible to also find a specific Attribute. Please refer to the following example:

https://<piwebapihost>/piwebapi/attributes/search?databaseWebId=<databaseWebId>&query=Element:{Name:='ElementName'}Name:'AttributeName'

For your purpose, you may find it easier to use AssetDatabase FindElementAttributes.

Thank you so much, I now have it working using your example. I'll also look into the other controller method you mentioned.
