In accordance with our deprecation schedule, we'll be sunsetting versions 2.5 and 2.5beta1 of the DCM/DFA Reporting and Trafficking API on February 28th, 2017. On this date, all requests made against these versions will begin returning HTTP 403 errors.
If you're still working with these versions, we strongly encourage you to begin migrating to the most recent release to avoid an interruption in service. If you're not sure, or would like to know more about the migration process, refer to the migration guide.
As always, feel free to reach out to us with any questions that you have.
