Why Am I Getting a 401 Error with My Weather API?

Asked by CodeExplorer42
I'm having some trouble with the Weather API. I've coded everything as per the guidelines and double-checked that my API key matches the one provided on the OpenWeatherMap website. The URL seems correct, and I've placed my .env file outside the source folder as instructed. Despite all this, my console continues to show a 401 error indicating that resources failed to load. I'm at a loss and don't know what to try next! Any advice would be great.

Try printing your URL and API key to the console before making the request. A common cause of these errors is often a simple typo. Make sure that what you think you're sending is indeed what you're sending. If you're already doing this and it's still not working, maybe double-check the key for any extra spaces or hidden characters.

Itโ€™s possible that thereโ€™s a hidden error in your code. Sometimes, when we think weโ€™ve done everything right, thereโ€™s still a small typo or mistake. I suggest stepping back and rechecking everything, or even asking someone else to take a lookโ€”it might help you spot the issue more easily!

Have you tried making a manual request using Postman or a similar tool? It can help you see if your API key and URL are working properly outside of your code. If you share the request setup, we can also help you troubleshoot further.
