415 errors are annoying, but usually easy to fix. What is web code 415? It means the server doesn’t like the format of your request.
Even if you’re sending JSON, the server might expect XML or something else. Check the API docs—sometimes they’re weirdly specific.
Also, if you’re using a library like requests in Python, make sure you’re setting the headers right:
```python
headers = {'Content-Type': 'application/json'}
```
Postman’s a lifesaver for testing this stuff.
