Why Power Automate?
Tools You’ll Need
Before we dive into the tutorial, let’s get familiar with the tools we’ll be using:
Microsoft Power Automate
The primary platform for building our HTTP requests.
Postman
A free tool for running and testing HTTP requests.
Excalidraw.com
A free, easy-to-use tool for visualizing our application flow.
Setting Up Your First HTTP Request
In this tutorial, we’ll start by creating an HTTP request in Power Automate. Unlike traditional REST APIs where you have custom endpoints, in Power Automate, we work with POST requests and set up custom headers to manage our data. Here’s a brief overview of the process:
Create an Automated Cloud Flow
Start by navigating to "My Flows" in Power Automate, then click "New Flow" and select "Automated Cloud Flow."
Define Triggers and Actions
Set your trigger to "When an HTTP request is received," making the endpoint publicly accessible. Next, add an action for a response to confirm the setup.
Initialize Variables
Create variables to capture custom headers like token, method type, and action type. This step is crucial for defining how your HTTP request will be processed.
Custom Headers and Conditional Logic
We’ll delve into initializing custom headers and variables to handle various requests:
Custom Headers: Define headers such as token and method type, setting up your workflow to handle different types of data requests.
Validation: Implement conditional logic to validate tokens and method types, ensuring only authorized requests are processed.
Testing with Postman
Postman will be our testing ground. By sending HTTP requests with different headers, we’ll verify that our setup in Power Automate correctly processes and responds to each request type (GET, POST, PUT, PATCH, DELETE).
