I'm working on web application where I need to send some data using ajax with post method. So I have two choices to send data whether in JSON format or query prams. I'm confused which should I use? and is it safe to send data in JSON format?

  • sending data in the body is a bit safer than sending it in the query params... if you use HTTPS and send data in the body of a POST request it's pretty safe – lucasreta Feb 22 '21 at 05:03

As @lucasreta mentioned, if you use HTTPS, it doesn't really matter either way.

Both methods are widely used. I know that Google accepts a Post request with query params and responds with a JSON object for ReCaptcha Server side validation.

Sometimes, the decision to use one or the other (or both) is dependent on how easy your chosen back-end technology makes it for you to either parse out query params or serialize JSON.

I will say that there is a general trend in using JSON in the request body as opposed to query params.

I found a couple of SO questions that are more down the lines of what you are asking...
