Will the PI Web API communicate with the Pi Data Archive? I am trying to interface Ignition to Pi for a project and having problems. I would appreciate any input. Thanks!

If you're using OAuth with PI Server 2023, then there may be some differences in how you setup the communication (which would require reading the AIM documentation). But otherwise if you're using Windows Auth with 2023 or 2018, there shouldn't be any issue reaching the DA, assuming 5450 is open from the API server to the DA, and assuming you've correctly configured Kerberos delegation.
