These are considered "pass-through values" or "p." parameters, which can be added before any name={value} pair and instructs impact.com not to store the value. You would need to ask the brand to set up the metadata so that the "p." parameters will be auto-appended on all brand links.
For example, if you needed to pass a customerId, you could append &p.customerId=abc123 to any tracking link and it would be translated to the brand's landing page without impact.com collecting the value.
Scenario: ACME Inc. has a promo code or offer. They would like to have the discount applied automatically on their website when a user clicks through a tracking link (i.e. without the need to manually enter a code). They also want to allow partners to deep-link to any part of their site.
Solution: ACME Inc. can configure their website to automatically apply the discount if the landing page URL contains a query string parameter offer=10off.
The brand can then configure a pass-through value:
In the left navigation menu, select Content → Ads.
Hover over the relevant ad and select Update Ad → Metadata.
Select
[Toggle on] Add metadata to this ad, then set the relevant custom values.Select Save.
Now the partner will be able to use the ad to deep-link to any page, and the resulting landing pages will always have offer=10off appended.
