Configure account transaction category rates.
If an existing account transaction category is found (same account_id and transaction_category_id), it is updated. Otherwise, a new one is created.
For an interest rate, for example fine_rate, the field fine_rate or fine_rate_multiplier_percent must be passed. You can pass one or the other but not both. This rule applies to all interest rate fields. However, you can combine fixed amounts and multipliers for different interest rates. Note that zero (0) is considered a valid value.
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.
