get https://api-sandbox.pismolabs.io/statements-v2/v1/accounts//accounts-transactions-categories
Retrieves all interest rates related to an account, canceled or active.
An active interest rate has the attribute cancelled_at set to null.
Since there can be more than one account transaction category per account, there might be more than one active interest rate.
Note: This endpoint requires an account token - an access token encoded with a Pismo account ID. Tokens can expire quickly, which can result in a 401 Unauthorized message.
