Deletes an interest rate that's configured for an individual account.
If only accountId is provided, all account accrual rates are deleted for that account.
You can use the optional parameters transactionCategoryId, accrualType, and periodToCalculate to specify a subset of the account accrual rates that you want to delete.
For example, if you provide values for transactionCategoryId, accrualType, and periodToCalculate, then all account accrual rates configured for the specified account, transaction category, accrual type, and period to calculate are deleted.

NOTE: This endpoint requires an account-specific access token. Getting an account token requires you to call Get OpenID access token with an external account ID. Tokens can expire quickly, which can result in an Unauthorized message.
