Assembling the payment

Now that we have a transaction id, we can create our payment request body.Payments that don’t use the full amount of a transaction will bump out a new line of the journal based on the referenced transaction.
You can apply multiple transactions to a bill at the same time. Each transaction will be a separate payment.
FieldDescriptionExample
transaction_idID from transaction"1234"
amountPayment amount10000
accountID from account (If you want to categorize the transaction at the same time)"1234"
Example request body:
