Calling all SaaS ISVs – Build and certify your PowerApps, Flow & Logic Apps Connector

We are excited to announce that as an application or service owner, you can now develop connectors that allow your app to work with PowerApps and Microsoft Flow. This enables your customers to easily automate their business processes and create their own no-code line of business apps. 

An API connector is an Open API (Swagger) based wrapper around a REST API that allows the underlying service to talk to Microsoft FlowPowerApps and Logic Apps. It provides a way for users to connect their accounts and leverage a set of pre-built triggers and actions to build their apps and workflows.

By being a part of our growing connector family (currently at 125+), you can enable a wide range of business and productivity scenarios for your users. This post provides an overview of what connectors can do, why you should build a connector and how to get started! 

What Can a Connector Do

Developing a single connector enables an integration for three different Microsoft products – Flow, PowerApps, and Logic Apps.


Using Flow, your customers can automate tasks and build workflows in conjunction with other social and business applications. The possible workflows span across a wide variety of possibilities, for example:

  • Send email, text and push notifications 
  • Copy files between data sources
  • Automatically collect and organize business data
  • Streamline approvals and send instant alerts

Logic Apps

Logic Apps is the workflow engine that powers Flow. It enables pro-developers to visually or programmatically configure workflows in Azure. A connector in Logic Apps can enable your customers to Automate EAI, Business to business (B2B) and Business to consumer (B2C) scenarios while reaping the benefits of source control, testing, support, and operations. 


PowerApps enables users to build cloud connected and cross platform business apps using clicks and no code. 

Using PowerApps, your customers can build simple apps for line of business scenarios that read and write data to multiple cloud sources. Some examples of such apps include survey forms, timesheets, expense reporting, etc. Users can securely publish and share these apps to the web or mobile for use within their organization.

Why should you build a connector? 

As stated above, building a connector offers extensibility of your app through PowerApps and automation and integration through Flow and Logic Apps. The same connector can drive more usage of your service and your existing API without additional development.

Drive more usage

Increase reach, discoverability and usage of your service by publishing pre-defined task specific templates that integrate your app with our growing family of connectors.

The Flow and PowerApps gallery of connectors and templates make it easy for your users to get started. Embedding of the Flow experience within your app enables users to leverage pre-built templates from right within your application.

Expand the reach of your API

Enable power users to leverage your APIs and extend your solution without having to write code. Using simple clicks, a business user can create and share a multitude of solutions like the one shown below, for organizational or personal use.

How to Get Started

To build and submit an API connector, your app must fit the following criteria:

  • Business user scenario that fits well with Flow, PowerApps and Logic Apps
  • Publicly available service with stable REST APIs

Build a Custom Connector

The first step to building an API Connector is to build a fully functional Custom Connector within Flow or PowerApps. An API Connector is nothing more than a Custom Connector that is visible to all users of PowerApps and Flow.

The general process to build a connector involves multiple steps:

Submit for Certification

As part of our 3rd party certification process, Microsoft will review the connector before publishing. This process validates the functionality of your connector, and checks for technical and content compliance as well as scenario fit.

If your application is built on azure, every user of Office 365 Enterprise Plans will get instant access to the connector for your app.
