How to POST data from 1 application to other

An existing application wants to open a mendix application with some data. Normally we use deeplinks for this where all the data is transferred through url GET request parameters. Is it possible to use a http POST method where the existing application sends the data in the request body in json format and opens the mendix page? The mendix application should open and prefill some fields in the form.

I think the easiest way to do this is to use the deep link module. Send all data you want to prefill in the deeplink, create an object when executing the deeplink and show a page to the user with the newly created object.

Is there a specific reason you want to use a POST operation?
