Frequently Asked Questions
Does minifying change the data in my JSON?
No — minifying only removes whitespace that isn't part of a string value. The underlying data structure and values are unchanged.
Should I minify JSON before sending it in an API request?
It's common practice for production traffic to reduce payload size, though for local development readable, formatted JSON is usually more useful.
