How to create Azure Blob Storage custom creator for PowerApp

Creating a custom connector for Azure Blob Storage in PowerApps allows you to interact with files and documents stored in Azure Blob Storage directly from your PowerApps. Here are step-by-step instructions on how to create an Azure Blob Storage custom connector:

Step 1: Sign in to PowerApps

• Go to the PowerApps website (https://powerapps.microsoft.com) and sign in with your Microsoft account.

Step 2: Create a new custom connector

• Click on “Create” in the left-hand menu.
• Select “Custom connector” under the “APIs” section.

Step 3: Provide connector details

• In the “General” tab, give your connector a name (e.g., “Azure Blob Storage Connector”) and a unique ID.
• Optionally, you can add an icon and a description for the connector.

Step 4: Set up authentication

• In the “Security” tab, select the authentication type. For Azure Blob Storage, you can choose either “API key” or “OAuth 2.0”.
• If you choose “API key”, provide the necessary details such as the key name and the key value. If you choose “OAuth 2.0”, you will need to configure the authentication settings accordingly.

Step 5: Define actions and triggers

• In the “Definition” tab, you can define actions and triggers for your custom connector.
• To create an action, click on “New action” and provide a name, description, and request details. For example, you can create an action to upload a file to Azure Blob Storage.
• To create a trigger, click on “New trigger” and specify the event that should trigger the action. For example, you can create a trigger when a new file is added to a specific container.

Step 6: Configure actions and triggers

• For each action and trigger, configure the request details, including the HTTP method, URL, headers, and request body.
• Use the Azure Blob Storage API documentation (https://docs.microsoft.com/en-us/rest/api/storageservices/) to understand the required parameters and request structure.

Step 7: Test the connector

• In the “Test” tab, click on “New connection” and provide the necessary authentication details, such as the API key or OAuth token.
• Test each action and trigger by providing sample data and verifying the responses.

Step 8: Save and publish the connector

• Once you have defined and tested all the actions and triggers, click on “Save” to save the connector.
• Optionally, you can click on “Publish” to make the connector available to other users in your organization.

Step 9: Use the connector in PowerApps

• Open your PowerApps application and go to the screen where you want to use the Azure Blob Storage connector.
• Add a control that can trigger the action or respond to the trigger (e.g., a button or a data card).
• Configure the control to use the Azure Blob Storage connector and select the desired action or trigger.

Step 10: Test the integration

• Preview or publish your PowerApps application and test the integration with Azure Blob Storage.
• Verify that the actions are performed correctly and triggers are activated when expected.

By following these steps, you can create a custom connector for Azure Blob Storage in PowerApps and seamlessly interact with files and documents stored in Azure Blob Storage from within your PowerApps applications. Custom connectors provide powerful integration capabilities, enabling you to extend the functionality of your PowerApps and connect to various external systems and services.
