HTTP request without POJO classes

I am currently trying to get an auth token given some body of either application/json data or application/www-x-urlformencoded. This means that i'd be using an map or a POJO class respectively. The issue is that i am going to be receiving any variation of parameters that need to go into a POJO class. For example the auth request could include:

clientId :1234
clientSecret : 1235

or it can include something like

clientId:1235
clientSecret:1234
appid:21345
etc: etc

I have no way of predicting what will be in the body so i cant just make every variation of json body as a class.

Is there a way to dynamically create a class, or more preferably, emulate the class in a way that allows me to specify the member variables at runtime?

I need a way to create an object that i can include in my RestTemplate exchange function that has dynamically named member variables

Do you need all the potential fields in your pojo? Or can you progress with a subset of known fields? Then you can just define the subset. If you use jackson as a json mapper, it will just discard additional fields as far as I know, unless you tell it to throw exceptions when json contains more fields than the pojo.

Maybe this is of help: https://www.baeldung.com/jackson-mapping-dynamic-object
