# Review Transactions

## Overview

Interac transactions may occasionally be placed under-review to pass fraud checks, ensuring the security of financial operations. During this process, transactions are temporarily held. This safeguard helps protect both consumers and businesses from unauthorized transactions and potential financial loss.

Customers are notified about the review status, and further action may be prompted if necessary to confirm the transaction's legitimacy. See [possible actions](/api-reference/operations/review-transactions.md#possible-actions) for more information.

{% hint style="warning" %}
While all Interac transactions undergo additional fraud screening, only a select few transactions may be placed under-review.
{% endhint %}

{% hint style="warning" %}
**Note**

* Upon investigation if the transaction is a fraud or scam, then the transaction is cancelled.
* Upon investigation if the transaction is legitimate, then transaction is completed.
  {% endhint %}

{% hint style="info" %}
**What can trigger an Interac Fraud alert?**

* Interac does not share the reason for flagging a transaction for fraud.
* Here are some situations that may trigger a transaction to be in-review for fraud:
  * When the same person attempts multiple transactions on the same day
  * When the email used belongs to a domain that is recently registered
  * When the person attempts to complete the payment using a suspicious browser fingerprint (IP address, browser, device, time-zone)
  * When the person attempts to deposit with multiple bank accounts
    {% endhint %}

See the [API reference](/api-reference/operations/review-transactions.md#interac-fraud) for more information on how to take action on an in-review Interac transaction.
