### Test integration
---

You can run a test request. If the request body contains a dynamic reference to a profile attribute and/or an event data from preceding nodes, then you can define the context using [test profile data](/docs/settings/configuration/test-profiles). 


<div class="admonition admonition-note"><div class="admonition-icon"><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" stroke-width="2.5"><path stroke-linecap="round" stroke-linejoin="round" d="M13 16h-1v-4h-1m1-4h.01M21 12a9 9 0 11-18 0 9 9 0 0118 0z" /></svg></div><div class="admonition-body"><div class="admonition-content">

Complete description of the feature is available in [Testing outgoing integrations](/docs/automation/test-requests-for-outgoing-integrations).

</div></div></div>



1. In the **Test integration** section, click **Send test request**.  
    **Result**: A test request builder opens. If:
    - a request body contains dynamic references, the request preview appears after you select the context of test profiles and events.
    - a request body contains static data, the preview of the body request appears immediately.
    <figure><img src="/api/docs/image/54176ad07f146575310749eba44b7c2f42c1b327/docs/automation/_gfx/test-request-builder-empty.png" class="large" alt="An empty test request builder"><figcaption>An empty test request builder</figcaption></figure>
2. If your request contains dynamic references (otherwise, the options aren't available):   
    - From the **Test profile** dropdown, select a test profile in the context of whom the test request will be performed.  
    - From the **Event context** dropdown list, you can select a particular occurrence of an event  whose values/information will be used for the test request.  
        1. Select a test profile.  
            **Result**: A history of test profile events appears.  
            <figure><img src="/api/docs/image/54176ad07f146575310749eba44b7c2f42c1b327/docs/automation/_gfx/event-stream-test-profile.png" class="large" alt="A stream of events of a test profile"><figcaption>A stream of events of a test profile</figcaption></figure> 
        2. From the list of events, select one whose data you want use as a context. If there is no event you can use, in the upper-right corner of the pop-up, click **Define own event** and provide the body of the event.
        3. Confirm by clicking **Apply**. 
3. Verify the request body. If there is something you want to change, come back to the node settings from previous steps.  
3. If the request body is ready to test, in the upper-right corner, click **Send request**.  
    **Result**: The response section appears and the **Update response event** button becomes active.  
4. Optionally, you can update response event with new parameters by clicking **Update response event** in the upper-right corner.
