How to Implement Client Tags for Reporting & Customer Data Prefill
To add client tags to a Partner Page integration for the purpose of enhanced reporting, add query string parameters to the respective URL in the following format*:
?tag.key_1=value_1&tag.key_2=value_2
To prefill customer data fields in a Partner Page for the purpose of decreased friction in user experience, add query string parameters to the respective URL in the following format*:
?app.key_1=value_1&app.key_2=value_2
*The first query parameter appended at the end of a URL/path should start with a question mark ?; all subsequent parameters should start with an ampersand &.
In the above example, clientId is available as a tag for reporting purposes and the partner page "loan amount" field will be prepopulated with the value of "$10,000" for the consumer when the page is rendered.
Supported Client Tag Keys (for any integration type)
These are the keys that are currently fully supported across all Engine partner page types. Please note that the keys below are case-sensitive:
agentId
campaignId
clientId
deviceid
medium
sourceId
subid
subid1
subid2
subid3
target
trafficsource
userid
If a different key is needed, please reach out to your Partner Manager - we may be able to accommodate, but adding nonstandard keys will increase the time it takes Engine to report Client Tag values back to you and is therefore not recommended.
