OSIsoft is pleased to announce the release of PI Web API 2018 SP1. This is a standalone installation kit available at my.osisoft.com, and is grouped together with PI Server downloads. The PI Web API is a suite of REST services that provide access to PI System data. The product is a member of the Developer Technologies suite of products and is targeted at providing cross-platform, multi-user programmatic access. Some highlights of this release are:

  • Notifications
    • Read for child NotificationContactTemplates

    • Returns a set of recorded values (x-axis) with another set of data for any number of streams (Y, Y', Y''... axis) that are interpolated based on the points returned for the x-axis
  • Stream Updates (CTP)
    • Client code will be notified of changes in AF metadata through an Exception item in the response payload.
    • The selectedFields parameter is now honored in both registration and poll for updates.
    • Responses now include PreviousEventAction information with each data value.
    • Error messages are returned for markers that are no longer valid with every poll using that marker. Previously, the error message would be returned only once.

  • The version of Web ID returned by PI Web API can be configured
