# Feedback to user

Once the **PKSA** receives a transaction request from the **HAS**, it should display it to the user and ask for approval or denial.

{% hint style="info" %}
It is strongly suggested to the **APP** and the **PKSA** to display part or all of the `uuid` of the transaction request to the user. This will allow them to match it on both endpoints and be sure they approve the right transaction.
{% endhint %}
