1. For the selected callback, open **Settings**.
2. The **Check callback** modal window opens. Add a valid envelope UUID and click the <img src="/files/Ryo93nDHnwccaQWjPBHt" alt="" data-size="line"> button.

{% columns %}
{% column %}
3\) If the specified envelope UUID matches the configured filters, a corresponding message appears, and the **Send a callback** button becomes active.
{% endcolumn %}

{% column %}

{% endcolumn %}
{% endcolumns %}

4. Click the <img src="/files/vQbvDFDfcrrqnZ5S3oxI" alt="" data-size="line"> button. The modal window shows:

{% columns %}
{% column %}

* envelope UUID
* response code
* response body
  {% endcolumn %}

{% column %}

{% endcolumn %}
{% endcolumns %}

You can send the callback again, return to the previous step (enter envelope UUID), or cancel the action.

5. If the specified envelope UUID does not match the configured filters, a message listing the mismatches is displayed.

After that, you can go back to the previous step, enter another envelope UUID, or cancel the action.
