Trouble with API key validation in Postman through RapidAPI

Other Questions RapidAPI
1

I’m new to using APIs and I’m stuck with a problem. I picked RapidAPI for my first try but it’s not going well.

When I test the API in Postman, it says my API key isn’t right. But I’m sure it is! The Chrome console shows a 404 error.

Here’s how my setup looks:

const SECRET_CODE = 'abc123xyz789';

export { SECRET_CODE };

I’m using VSCode with LiveServer. My folders are set up like this:

  • project
    • css
    • js
      • main.js
    • index.html

My main code is:

import { SECRET_CODE } from './secret';

fetch('https://example-weather-api.com/forecast?city=Paris', {
  method: 'GET',
  headers: {
    'x-api-key': SECRET_CODE,
    'x-api-host': 'example-weather-api.com'
  }
})
.then(data => data.json())
.then(info => {
  console.log(info);
  console.log(info.details);
})
.catch(problem => {
  console.error(problem);
});

What am I doing wrong? Help!

Hi mikezhang, I’ve run into similar issues before. From what I can see, there are a couple things that might be causing your problem:

First, as Alice45 mentioned, you need to use the correct header names for RapidAPI. They should be ‘x-rapidapi-key’ and ‘x-rapidapi-host’ instead of what you have now.

Second, make sure your API endpoint URL is correct. A 404 error usually means the server can’t find what you’re looking for. Double-check the URL structure in the API docs.

Also, I noticed you’re importing the API key from a separate file. This can sometimes cause issues with browser security policies when using LiveServer. You might want to try hardcoding the key temporarily just to rule that out as a problem.

Lastly, have you tried testing the API directly in Postman without going through your code? That can help isolate whether the issue is with the API itself or your implementation.

Hope this helps! Let us know if you get it working.

hey there! looks like you’re having some trouble with your api setup. have you double-checked that you’re using the correct headers for rapidapi? make sure you’re using ‘x-rapidapi-key’ and ‘x-rapidapi-host’ instead of ‘x-api-key’ and ‘x-api-host’. that might be why you’re getting that 404 error. good luck!

I’ve dealt with similar API issues before. Here’s what I’d suggest:

First, double-check your headers. RapidAPI uses ‘x-rapidapi-key’ and ‘x-rapidapi-host’, not ‘x-api-key’ and ‘x-api-host’. That’s likely causing your 404 error.

Next, verify your endpoint URL. Make sure it exactly matches what’s in the API docs, including any trailing slashes or query parameters.

Also, try testing the API directly in Postman without your code. This can help pinpoint if the issue is with the API or your implementation.

Lastly, check if your API key has the right permissions for the endpoint you’re trying to access. Some APIs restrict certain endpoints based on your subscription level.

If you’re still stuck after trying these, let me know and we can troubleshoot further.
