From the left navigation bar, select [Search] and enter "My Brands."
Select My Brands from the Screens column.
Find the brand for which you want to test your piggyback pixel, then, under the Actions column, select [Drop-down menu]→ Tracking Integration.
For the piggyback pixel you want to test, under the Actions column, select [Drop-down menu]→ Test. In the new window, enter the landing page URL and select Launch Test.
You will get redirected to a page with two options.
If the internal tracking test URL has properly been set up, you will be led to the landing page for the tested campaign. Select Trigger Conversion Piggyback and impact.com will call the pixel, which will show up as a conversion in your third-party tracking system
Continue through the brand's conversion path and complete an end-to-end test. This will show up as a transaction in your third-party system and as a pending action in Impact.
