A program transaction type is used to associate a transaction type with a transaction category. It can also be used to set the charge order. For more information, refer to How the program uses configurable entities.
Note: Only debit transactions and transactions that impact the statements can be used to create program transaction types. Use the List transaction types endpoint to see if a transaction type is a debit (credit = false) and if it impacts the statement (posted_transaction = true).
