How to send additional data to server, PUT, DELETE, GET, POST?

Hi guys.
I am building an API with php.
I need to support Datable with SERVERSIDE enabled.
These are all the methods in my API flow (GET, POST, PUT, DELETE).

and I need to know how the API consumer can send additional data on each request to the server.
the main reason is that the API needs to validate a TOKEN, to be able to show or not Data.
