Frequently Asked Questions
What is a MIME type?
MIME (Multipurpose Internet Mail Extensions) types are labels that identify the nature and format of a document. They are used in HTTP headers as Content-Type to tell browsers and servers how to handle files.
What is the MIME type for JSON?
The correct MIME type for JSON is application/json. Always set this as your Content-Type header when returning JSON from an API.
What MIME type should I use for unknown files?
Use application/octet-stream for unknown binary files. This tells the browser the content is binary data and should be downloaded rather than displayed.
