asset field: an NGN vault has asset: "NGN", and a EUR vault has asset: "EUR".
Each vault works like a virtual account. You get bank details to receive into it, it keeps its own balance, and you pay out from it.
How it works
Example
A business that collects in Nigeria and Europe holds an NGN vault and a EUR vault. Customers pay into each vault’s bank details, and each balance builds up in its own currency. The business pays EUR suppliers from the EUR vault, or converts NGN to EUR first.Use deposit details exactly as the API returns them. A vault can return several options, for example one per payment rail. You can’t set a vault’s
asset when you create a vault.
