This guide explains how to test specific API endpoints directly in your Chrome browser by injecting the necessary authentication headers (API Key) using the ModHeader extension.
Prerequisites
Google Chrome Browser.
Your VictoryAPI Key (from your user dashboard).
Step 1: Install ModHeader
Open the Chrome Web Store.
Search for "ModHeader".
Click Add to Chrome and confirm by clicking Add extension.
Step 2: Configure the Header
Click the ModHeader icon (usually a blue icon with white lines) in your browser's toolbar.
In the Request headers section, you will see two input fields:
Name: Enter the required header key for VictoryAPI (x-vapi-key). Note: Check your documentation for the exact name.
Value: Paste your actual API Key here.
Ensure the checkbox next to the header is checked (active).
Step 3: Test the Connection
Open a new tab in Chrome.
Enter the URL of the VictoryAPI endpoint you want to test.
Example: https://api.v1.victoryapi.ir/countries (Replace with every endpoint you want to test).
Press Enter.
If the configuration is correct, the browser will display the JSON data returned by the API instead of an authentication error.
