As you create digital models of your physical world, you need a simple and seamless way to incorporate your digital models into your business applications. This allows you to gain faster insights and drive better business outcomes.

 

Azure Digital Twins is a powerful way to contextualize your data by creating twin graphs based on digital models of your physical world. Microsoft Power Platform is an extensible platform of low-code tools that makes it easy to create flows using Power Automate and apps using Power Apps. Together, Microsoft Power Platform and Azure Digital Twins allow you to build powerful workflows and apps that incorporate Azure Digital Twins into your business workflows and applications.    

 

Azure Digital Twins connector

 

The connector is a wrapper around the Azure Digital Twins data plane APIs, and provides a simpler way to make these API calls as prebuilt actions in Power Automate and Azure Logic Apps, and as functions in Power Apps. You can also integrate the Azure Digital Twins connector with 700 other Power Platform connectors, to build flows or apps by ingesting from other systems into digital twins or responding to events. Additionally, you can use the Azure Digital Twins connector to build your flows in Azure Logic Aps. This article shows how to create a recurring workflow in Power Automate that adds digital twins and a relationship between them to your Azure Digital Twins instance.
