Create a new, active ledger with a linked automatcher. This endpoint also allows you to link an existing automatcher to the ledger by passing an existing bankAccountNumber. Optionally, you can also specify a BSB. If no existing automatcher is linked, a new one will be created.
\nIf you wish to link a PayID to the automatcher you will need to use the PayID endpoints.
\nThe API response will vary based on whether a new automatcher is being created, or an existing automatcher is being linked to the ledger account. Automatcher activation is an asynchronous process that can take a few minutes to complete. If a new or inactive automatcher is linked, the API will respond with isActive: false, and the statusDescription: 'Account is being setup for Npp. Please allow a few minutes for the account to become active'.
