The Intergraph Smart® P&ID Smart API application allows Smart P&ID users to connect to their site and plant data. Using a simple application such as Postman, authenticated users can send requests to the Smart P&ID database to retrieve or update data, find relationships between database items, and so forth.
Make sure you read the Smart P&ID Smart API Installation and Configuration Guide before installing Smart P&ID. The information contained in this guide will help you install Smart P&ID and make the required connections to your SAM (Smart API Manager) server.
A full range of documentation can be found at the Hexagon PPM Documentation site.
Also, you will find details about using the Smart Configuration Manager, a utility designed to help you get up and running smoothly and quickly.
