Hello Duo, 

Our requirements: 

We will have a multiple subscribers using our service. Currently, we have one single account under onespan for the integration of onespan into our system. We are using the saved layout for applying the fields in the document. Since, we will have different subscribers, if we save a layout for each of them, the layouts can be accessed by all the clients, which we don't want them to. So, we have decided to separate the account for each of them via sender account.
