IA-Connect is a Robotic Process Automation (RPA) platform which adds RPA functionality from Power Automate Cloud Flows to on-premises virtual machines or over Citrix or Microsoft Remote Desktop (RDS) connections. The IA-Connect Connectors provide over 650 actions, allowing you to automate every type of on-premise application directly from a Power Automate Cloud Flow. All IA-Connect actions are available directly from your Power Automate Cloud Flow providing easy integration between Cloud based and on-premises applications, the ability to leverage existing Power Automate conditions, loops, dynamic content, expressions and exception handling in your RPA processes. Utilising the IA-Connect Connectors also provides full execution history and auditability from the Flow run history whilst also removing the need to have a separate application/console/studio for developing your RPA processes.

Prerequisites

To use any of the IA-Connect Connectors, you must install the IA-Connect software. This is free to test for 30 days, following which you will require an IA-Connect license.

The IA-Connect software consists of two main components:

  • The IA-Connect Orchestrator, which is an Azure WebApp which you would host in your own Azure tenant. This handles the routing and security of RPA Flows to one or more on-premises or cloud-based virtual machines.

  • The IA-Connect Agent and Director, which is installed onto the virtual machines where the software you wish to automate is accessible. Additionally, the IA-Connect Agent can run inside a Citrix or Microsoft Remote Desktop Services (RDS) session, where the RPA commands are passed down a virtual channel into the remote session for execution. The IA-Connect Agent can be run from a network share and does not require installation.

Available IA-Connect Connectors

The available IA-Connect Connectors are:

  • IA-Connect Dynamic Code
  • IA-Connect Java
  • IA-Connect Mainframe
  • IA-Connect Microsoft Office
  • IA-Connect SAP GUI
  • IA-Connect Session
  • IA-Connect UI
  • IA-Connect Web Browser
