What Is A Dynamic Offer Postback URL?

A dynamic offer postback URL is an alternative solution to providing your advertiser with multiple offer-specific postback URL’s. Typically, a new postback URL is generated per Offer that you create and will contain a hardcoded Offer ID value.

This alternative method leverages a CAKE token that is placed in the advertiser’s landing page to dynamically send the CAKE Offer ID and Request ID as a single value. This enables your advertiser to deploy a single Postback URL for server tracking across multiple offers.

What Is The #oreqid# Token?

#oreqid# is a token that is required when configuring a dynamic offer postback URL. This token combines the Offer ID and Request ID into a single value. When you click on a standard CAKE tracking link, you can see the structure in the Landing Page URL has the Offer ID first, then the Request ID value second, separated by a dash. Because this value includes the Offer ID, it eliminates the need to hardcode the Offer ID (o= parameter) on multiple postbacks.

Example Of The #oreqid# Token Values

Link Type	Example Output
Standard Tracking Link	15-335898
Lite Click Link	RhrdCCqlefhzcTGbP4wtVqso2Rxgfp3nmGYrhLIFYhSf RBvHT8uq2AdCOJ2tIIlk8j9h0ycURl2jgO1lZIAJf1ZoHn 5RU2Tdl4orA8NVG4wch328adzF3WFxbhMkMvOc4N wbaUb7z5FxUW
Lite Click Link with Shorten Request ID Enabled	B2701DC7-B528-4532-8401-E952901520C7

Note: The structure of the CAKE Request ID changes when using Lite Clicks and Lite Clicks with Shorten Request IDs. Unlike the Request ID on a Standard Click, Lite Click Request IDs use an encrypted format that intentionally obfuscate the Offer ID or Request ID. You can check the Click Report to ensure the correct offer is being attributed.

Example Of The Dynamic Offer Postback URL Structure

Example: https://trackingdomain.com/p.ashx?e=1&f=pb&r=15-335898&t=TRANSACTION_ID

Note: The o= parameter is removed when using a Dynamic Offer Postback. The r= parameter is where the oreqid value must be returned. The e=1 value above is just an example and will change with each Advertiser/event.

How To Configure A Dynamic Offer Setup

To configure a dynamic offer setup, follow these steps:

Ensure the advertiser can capture and store at least 1 dynamic value passed to their landing page(s)
Have the advertiser identify the parameter that will receive the oreqid dynamic value
Add #oreqid# to that parameter on the Offer Redirect Parameters field.
Provide the advertiser with the dynamic offer postback structure (see above)
Run a test to ensure the oreqid value is returned into the r= of the postback

Note: Click_id in the example above is just an example, and not the standard value that your advertiser will use.
