API: Get Client ID (client_id) by id_value/id_code

[Colin]

I'm trying to find a way to retrieve the client_id of a client via the API using only the clients id_value/id_code (Client ID displayed in the client dashboard) as a source.

Is there a way to achieve this? I'm attempting to add client transactions via the API where the client id_value, amount, and currency are the only data provided.

are you able to do it?
