Integrate Logic Apps & SQL Server with API Connection & Credentials in Key Vault
Introduction
Azure Logic Apps and SQL Server are two of the most popular cloud products for application development. In this blog post, we will discuss how to integrate these two services by using an API connection and credentials kept in Key Vault. We will review the advantages of this approach, and provide a step-by-step guide for setting up the connection.

Advantages of API Connection & Key Vault
An API connection between Azure Logic Apps and SQL Server provides a secure, reliable connection for data transmission. By storing credentials in Key Vault, the API connection can be set up without exposing sensitive information. The connection is also more efficient, as data is only sent when necessary.

Step-by-Step Guide to Setting Up API Connection & Key Vault
Step 1: Create a Key Vault
The first step in setting up an API connection between Logic Apps and SQL Server is to create a Key Vault. In the Azure Portal, search for “Key Vault” and select the “Create” option. Enter the desired name, resource group, and region, and then select “Create”.

Step 2: Create an App Registration
Next, create an App Registration in Azure Active Directory. This will allow Logic Apps to securely access the credentials stored in Key Vault. In the Azure Portal, search for “App Registrations” and select the “Create” option. Enter the desired name and select “Create”.

Step 3: Add Access Policies to the Key Vault
In order for Logic Apps to access the credentials stored in Key Vault, you must add Access Policies to the Key Vault. In the Azure Portal, select the Key Vault you created in Step 1 and select “Access Policies”. Then select “+ Add Access Policy” and enter the details for the App Registration you created in Step 2.

Step 4: Create a Service Principal in Azure Active Directory
Next, create a Service Principal in Azure Active Directory. This will allow Logic Apps to securely access the credentials stored in Key Vault. In the Azure Portal, search for “Service Principals” and select the “Create” option. Enter the desired name, select the App Registration you created in Step 2, and then select “Create”.

Step 5: Add a Connection to Logic Apps
Finally, add a connection to Logic Apps. In the Azure Portal, search for “Logic Apps” and select the “Connections” option. Select “+ New Connection” and select the “SQL Server” connection type. Enter the desired name, select the Service Principal you created in Step 4, and then select “Create”.

Conclusion
Integrating Logic Apps and SQL Server via an API connection and credentials stored in Key Vault is a secure and efficient way to transmit data between the two services. By following the steps outlined in this post, you can easily set up the connection for your application.
