About this tool
Build HTTP header blocks quickly for API debugging, curl testing, and integration docs. Populate standard fields like Host, Authorization, Content-Type, and Accept, then append custom headers in one output. This helps reduce mistakes when sharing reproducible request examples.
Frequently Asked Questions

Is this for requests or responses?
This generator focuses on request header construction for API calls.
Can I use generated headers in curl?
