Transfers are subject to respective regulations and the intention of this short article is not to discuss the business aspect of transfers. We will only describe what to do technically in Connect ID in order to add a registration in a given MA (which sometimes, but not always, will become an actual transfer).

As a prerequisite, we recommend that you read this article which discusses how to build a user interface for displaying potential duplicates. Adding a registration for an existing person is always a result of a decision made by a human operator using the aforementioned user interface.


If you already determined that a person you are trying to register in your FMS, already exists internationally (you will receive a potential duplicate from Connect ID), you will want to take over / reuse their FIFA_ID. The process is very simple as the system automates most of the actions.


The only thing you need to do is to run: AddRegistration(...) method and pass information about the new registration (to indicate that this person will e.g. become an amateur, football, player, in your MA.

Note, that if a conflicting registration exists you will receive an error. In such cases it will be useful to set a Force flag to True. This setting will cause the conflicting registration to disappear and your registration to be added. Please note that the system takes care of the FIFA regulations here automatically, for example:

  • if you add a registration for Beach Soccer in your MA the system will not remove any existing registration
  • if you add a registration for Football in your MA the system will remove an existing football registration


Some MAs might wonder whether it's not enough to use UpdateRegistration(...) method for a transfer. The main argument is that using AddRegistration(...) is always safe, while using the UpdateRegistration(...) might lead to mistakes. Consider two examples below.


Example 1


There is a Futsal player in MA_X. 

MA_Y uses AddRegistration(...) to add a Football registration in MA_Y.

As a result we now have 2 registrations in 2 different MAs which is OK.

If MA_Y used UpdateRegistration(...) we would replace Futsal registration with a Football one which would be wrong.


Example 2


There is a Football player in MA_X. 

MA_Y uses AddRegistration(...) to add a Football registration in MA_Y. This method takes into consideration FIFA rules automatically and removes registration in MA_X (there cannot be 2 football registrations at the same time).

As a result we now have 1 registration in MA_Y which is OK.

If MA_Y used UpdateRegistration(...) the behaviour would be identical in this case.



As you can see from these examples using AddRegistration(...) for transfers works in all cases.
