How Do I Send POST Requests with JSON Data?

By default, POST requests use application/x-www-form-urlencoded. To send JSON data, you need to add the Content-Type: application/json header manually, though some software/tools may do this automatically.

Before trying on your target site, we recommend using a testing site like httpbin.io to verify that the parameters are sent correctly.

Ensure that the parameters are sent and the format is correct. If in doubt, switch between both modes to confirm that the changes are applied correctly.
