Payolution request flow

Both invoice and installment utilize the same request flow. It basically consists of the following requests:

• Calculation (for installment only): to calculate the installment amounts, dues, and durations.
• Pre-check (optional): to check the user information in order to make sure that all the needed information is correct before doing the actual pre-authorization.
• Pre-authorize: to perform a payment risk check which is a mandatory step before every payment. The payment is basically considered accepted when it is authorized.
• Re-authorize: to update an existing authorization if necessary.
• Revert: to cancel the authorization step which basically cancels the payment before capturing.
• Capture: to capture the payment and receive money from the buyer.
• Refund: to refund the buyer when returning products.
