GenerateToken call stores parameter into the session
In generell all POST Parameters are allowed. If GenerateToken is called with a set of parameters, those parameters will be saved into the session.
During the execution of the payment the parameter which are sent in by the frontend form will be merged with those parameters which are saved to the session.
In general it is not possible to submit a parameter twice, eg. when ACCOUNT.CURRENCY=EUR is already submitted within GenerateToken it can't be submitted again by the frontend form.
Parameters which are not allowed in GenerateToken
Because they are sent by COPYandPAY frontend form automatically based on the brand selection.
