RapidAPI authentication fails in Postman - API key seems incorrect

API Key Authentication Problem with RapidAPI

I’m new to working with APIs and chose RapidAPI as my starting point. However, I keep running into authentication issues when testing my requests in Postman. The error message indicates my API key is invalid, but I’ve double-checked it multiple times.

The browser console shows a 404 status error when I make the request. Here’s my current setup:

Configuration file (settings.js):

const SECRET_KEY = "abc123def456ghi789";

export {SECRET_KEY};

Main application code:

import {SECRET_KEY} from './settings.js';

fetch("https://weatherapi-com.p.rapidapi.com/current.json?q=Paris", {
    "method": "GET",
    "headers": {
        "X-RapidAPI-Key": SECRET_KEY,
        "X-RapidAPI-Host": "weatherapi-com.p.rapidapi.com"
    }
})
.then(data => data.json())
.then(result => {
    console.log(result);
    console.log(result.data);
})
.catch(error => {
    console.error(error);
});

I’m using Live Server in VS Code for development. What could be causing this authentication failure?

The 404 error is likely a result of using an invalid or inactive API key. The key “abc123def456ghi789” appears to be a placeholder. Make sure to replace it with your actual RapidAPI key from your dashboard. Furthermore, even if you’re using a free plan, you must subscribe to the WeatherAPI service via RapidAPI’s marketplace. Don’t forget to check for any usage limits as these can result in authentication errors rather than clear rate limit notifications.

I encountered a similar issue when starting with RapidAPI. It appears that the API key you’ve shared could be a placeholder or an incorrect key. Ensure that you have obtained the correct API key from your RapidAPI dashboard after choosing the WeatherAPI subscription plan, which may include free options. Additionally, verify that you are subscribed to the specific endpoint you are trying to access, as some APIs require separate subscriptions for different endpoints. Once you replace the placeholder key with the correct one, your requests should work without authentication errors.

that key’s def fake lol. go to ur RapidAPI account settings and grab the real one - mine was way longer with diff characters. also, make sure you subscribed to WeatherAPI in their marketplace. even free tier needs a subscription first.
