❓ Frequently Asked Questions
What is a MIME type? ▾
A MIME type (like text/html or application/json) tells browsers and servers what kind of data is being sent. Without correct MIME types, browsers may display files incorrectly or refuse to process them.
What MIME type should I use for JSON APIs? ▾
Always use application/json as the Content-Type header for JSON API responses. Some older systems use text/json but application/json is the standard.
What happens if I use the wrong MIME type? ▾
Browsers may display files as text instead of rendering them, refuse to execute scripts, or trigger download dialogs. Web servers must serve each file type with its correct MIME type.
