How to Secure HTTP Requests Using OAuth Authentication in Power Automate


When working with workflows triggered by HTTP requests, it's important to ensure that only authorized users can start the workflow. One effective way to manage authentication is through OAuth authentication, which allows you to limit access to specific users within your organization. By implementing OAuth, you can ensure that only approved users have permission to trigger the workflow, improving security and protecting sensitive data. To set up OAuth authentication for the "When an HTTP request is received" trigger in Power Automate, you'll need a Power Automate account, Azure AD tenant, app registration in Azure AD, admin access to Azure Portal, HTTP request trigger, valid API permissions, OAuth 2.0 Token Endpoint knowledge, and a Postman or API testing tool (optional). Once set up, you can configure the flow and logic for your Power Automate flow.
