What are REST API headers and how do they work?

REST API headers are key-value pairs sent in HTTP requests and responses, providing essential information about the request or response.

Can you give me examples of common REST API headers?

Sure! Common headers include 'Content-Type', 'Authorization', and 'Accept'. Each serves a specific purpose in the API communication.

How do I set headers in a fetch request?

You can set headers in a fetch request by using the 'headers' option. For example: fetch(url, { method: 'GET', headers: { 'Authorization': 'Bearer token' }});

What happens if I forget to include headers?

If you forget to include necessary headers, the API may return an error or not process your request correctly.
