# How to enable requests for exchanges in specific currency pairs

Exchanges initiated by clients in specific currency pairs through the B2CORE UI can be configured to require admin approval.

When clients create exchanges in these specific pairs, requests of the **Exchange** type are created and listed on the [Clients > Requests](https://docs.b2core.b2broker.com/back-office-guide/clients/requests) page. These exchanges are executed only after corresponding requests are approved by the admin, using the rates specified in the approved requests.

To enable requests for exchanges in a specific currency pair:

{% stepper %}
{% step %}
Navigate to **Currencies** > **Currency pairs**.
{% endstep %}

{% step %}
Select the currency pair for which you want to enable exchange requests and click the **Edit** button.
{% endstep %}

{% step %}
On the **Edit currency pair** page, select **Yes** for the **Request required** option.
{% endstep %}

{% step %}
Click **Save** to apply the changes.
{% endstep %}
{% endstepper %}
