Getting Started: What is a PowerApps Custom Connector?
A custom connector is a tool that allows you to connect your custom APIs to the Microsoft Power Apps or Microsoft Power Automate and Azure Logic Apps.
A Custom Connector is a wrapper around an API that allows communication.
Custom connectors act as bridges between PowerApps and external services (APIs) or data sources. They enable you to access, retrieve, and manipulate data, expanding the capabilities of your apps.
How to configure a Custom Connector in Power Apps to call an API?
For adding an API in Power Apps or Power Automate, there are different options available, which can be resume in 2 scenarios:
- Scenario 1: Create a new custom connector from scratch (New).
- Scenario 2: Create a new custom connector from an existing definition file (Import).
Creating a Custom Connector: Prerequisites
Before you embark on your custom connector journey, ensure you have the following in place:
Microsoft Power Apps: You must have a Power Apps account to create custom connectors.
Access to the API: You’ll need access to the API of the service or data source you want to connect to.
Basic knowledge of REST APIs: Familiarize yourself with REST APIs, as custom connectors are typically built around them.
API Information for the PowerApps Custom Connector example
For this example, we will be using a free API called Reqres.
Reqres – is a hosted REST-API ready to respond to your AJAX
URL: https://reqres.in
API Get List of users method: https://reqres.in/api/users
