💡 Hint

Common Mistakes

Using -X POST instead of -X GET causes the server to expect data submission.

Using -d without data causes errors.

Using -I only fetches headers, not the full response.

The -X GET option tells curl to send a GET request, which is the default method to retrieve data.

💡 Hint

Common Mistakes

Using the wrong Content-Type header causes the server to misinterpret the data.

Forgetting to add the header can cause the server to reject the request.

The header 'Content-Type: application/json' tells the server that the data sent is in JSON format.

💡 Hint

Common Mistakes

Using key=value format instead of JSON.

Using double quotes outside without escaping causes shell errors.

JSON data must be enclosed in single quotes with double quotes inside to be valid and correctly parsed.

Confusing -D and -o options.

Saving both headers and body to the same file.

The -D option saves headers to a file, and -o saves the response body to a file.
