The API access key has already been obtained from the previous exercise unit.

Create a custom connector from an OpenAPI document

There are several ways of creating a custom connector for Power Apps. In this exercise, you will create one using an OpenAPI document. Suppose you have an OpenAPI document named openapi.json and an API access key provided by the professional development team.

1. After logging into Power Apps dashboard, open the Data blade and click the Custom Connectors menu on the left-hand side. Then, click the ➕ New custom connector button at the right-top corner and select the Import an OpenAPI file menu.

   

2. When a pop-up modal appears, give the name, InventoryManager, to the Connector name field and click the Import button to import the OpenAPI document, openapi.json. Then, click the Continue button.

   

3. As the OpenAPI document has everything you need to create the custom connector, click the ✅ Create connector button at the right-top corner.

   

4. Once the custom connector is created, you will see the message, ✅ Custom connector has been successfully created at the top of the screen.

   

5. Click the Custom Connectors menu on the left-hand side of the page, and you will see the custom connector created. The ➕ button at the right-hand side.

   

6. When a pop-up modal shows up, you will see the API Key field. Enter the API key for the web API, which is usually obtained from the web API's developers. Then click the Create button.

   

7. Go to the Connections menu, and you will see the new connection has been created.

   

A new custom connector from the OpenAPI document is now created and ready to be used within a Power Apps application.
