What is the difference between PUT and PATCH?

PUT replaces the entire resource. PATCH updates only the specified fields. If a user has name, email, and phone, PUT requires all three. PATCH can update just the email.

When should I use query parameters vs headers?

Query params for filtering data (page, limit, search). Headers for metadata about the request itself (auth tokens, content type, accepted formats).

What is a Bearer token?

A Bearer token is an authentication credential sent in the Authorization header. The server verifies the token to identify the user and their permissions.

Does the API Request Builder send real requests?

No. It generates code snippets only. Copy the generated cURL, fetch, or axios code and run it in your own environment.
