# Feedback Loop
source: https://developer.mastercard.com/open-finance-us/documentation/products/pay/feedback-loop/index.md

Feedback Loop provides a secure and standardized way to submit payment
outcome data for Open Finance Pay products. The data helps Mastercard
evaluate payment outcomes and continuously improve risk models.
Tip: We recommend sharing data at consistent intervals (monthly or bi-weekly) to ensure models stay current and product performance improves consistently.

You can submit feedback using either of the following methods:

* Use [Feedback Loop API](https://developer.mastercard.com/open-finance-us/documentation/products/pay/feedback-loop/api/index.md) to submit payment outcome data through a secure API using either plaintext JSON or an encrypted payload.
* Use [Feedback Loop Batch](https://developer.mastercard.com/open-finance-us/documentation/products/pay/feedback-loop/batch/index.md) to submit payment outcome data as files through an AWS S3 directory. Files can optionally be encrypted using Mastercard-provided encryption keys.
