Deposit Account APIs
Create Deposit Account
Creates a deposit account for a Customer (or customers). An account.created event is raised when the call was successful.
Each deposit account is created using a specific deposit product. A deposit product is a predefined set of terms associated with this deposit account (e.g. interest rate, spending limits).
Use checking as the default value for the deposit product field while building your solution in sandbox . Contact Unit to create other deposit products under your organization.
Deposit Account creation request supports Idempotency, ensuring that performing multiple identical requests will have the same effect as performing a single request.

Close Account
Closes an account. Closing an account is irreversible and can only be done by an Org user. An account.closed event is raised when the call was successful.
Closing an account will also close the cards associated with the account.
When closing an account with a balance of $1 or less, the funds will automatically be transferred to your organization's revenue account (see more at Account Low Balance Closure). When closing an account with a balance greater than $1, a check will be mailed to the business or individual address on file.
When closing an account with a negative balance, the balance will be considered a loss, and will be covered from your reserve account

Account Hold
An account hold temporarily reserves a specified amount of funds in the account balance, making that amount unavailable for other transactions.
While the hold reduces the account's available balance, the held funds remain in the account and are not transferred. When creating an AccountHold, the specified hold amount is deducted from the available balance, but the total balance remains unchanged.
