Add a Bank Account to an EstateAgent

Adds a new bank account to an existing estate agent's record.

A developer calls this endpoint to register a bank account for an estate agent, for example to enable outgoing payments. The estate agent to add the bank account to is located via reference or externalIdentifier, at least one of which must be supplied.

An estate agent can have at most one preferred bank account at any time: if the new account is added with isPreferredBankAccount set to true, the estate agent's current preferred bank account is automatically set to false. If the estate agent currently has no bank accounts at all, the new account is forced to be preferred, regardless of the value sent.
