# Terminologies



 Before you start Juspay FRM integration, get to know FRM terminologies:

* **Rule:** A rule is defined as a combination of entities - transaction filters and counters.
* **Program** : A program is a set of rules that merchant can create on the FRM module.
* **Sequential Mode** : In this mode, Juspay first invokes the FRM Engine. Based on the FRM response, the transaction is then routed accordingly.
  
  * If FRM returns **Proceed**  or **Flagged**  (requires review), the transaction is routed to the Payment Gateway (PG).
  * If FRM returns **Decline** , the transaction is not routed to the PG and is marked as **JUSPAY_DECLINED** .
* **Parallel Mode:** In this mode, Juspay invokes the FRM Engine and routes the transaction to the Payment Gateway (PG) simultaneously. As a result, the FRM response does not have any real-time impact on the transaction.
