http - How to pass POST Form Data from HTML to Java Rest Api -

i working on payment integration system in java rest api. gateway zaakpay. when user clicks proceed payment site redirected zaakpay payment gateway. after successful payment zaakpay redirects user returnurl.html. transaction results sent returnurl.html post form data in http request.

how capture post form data in request , how forward java rest api.

why payment gateway returning result returnurl.html ?

i think must have specified somewhere indicate payment gateway return result url , instead can provide controller url path .

after in order intercept post request need method in controller , here example of jersey based implementation of jax-rs

@post @path("/add") public response adduser(     @formparam("name") string name,     @formparam("age") int age) {  <================do whatever need here ====================>          return response.status(200)         .entity("adduser called, name : " + name + ", age : " + age)             .build();  }
