# How to enable additional AML check

You can add your personal account of the AML provider as an additional level of verification. If enabled, after successfully passing the default B2BINPAY AML check, the transfer is sent to your provider for additional verification. During the entire duration of both checks, the amount of the incoming transfer remains in *Pending*.

To enable custom AML check:

{% stepper %}
{% step %}
Click your user icon in the upper right corner of the page and select **Settings**.
{% endstep %}

{% step %}
In the **AML check** section, activate the toggle.
{% endstep %}

{% step %}
In the popup:

1. Select an AML provider. Currently, two AML providers are available: [Crystal](https://crystalintelligence.com/) and [Chainalysis](https://www.chainalysis.com/).
2. Enter your AML provider credentials: API key and API secret.
3. Specify **Risk for alert** to receive email notifications on suspicious transactions, and **Risk for block** to block them. The values from 0 (zero) to 100 are supported.
4. In the **Retries max** field, specify the maximum number of attempts to resend a request in case the AML provider doesn't respond.
   {% endstep %}

{% step %}
Click **Enable** to finish setup.
{% endstep %}
{% endstepper %}

The additional AML check is now enabled. All incoming transfers are now subject to two AML checks.

You can disable custom AML check or edit credentials anytime in your profile.
