# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zumrails.com/payments/interac-e-transfer/review-transactions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
