We support two separate links, one for successful completes, one for everything else

If you’d like to setup custom redirect URLs, contact your Dynata account manager. We don’t support redirect hashing; we use secure hasing in our system-to-system Callbacks.

We return a handful of query parameters describing the session result in the URL:


Transaction ID


The three part Dynata user ID


The user ID passed in the entry URL


The status of the transaction: C, P, or F.


A custom tracker ID that you may pass with the user in the entry URL.
