DAR Browser SDK
From Engineering Client Portal
To start using the Browser SDK, the following details are required:
- App ID (apid): Unique ID assigned to the player/site and configured by product.
- sfcode: Unique identifier for the environment that the SDK should point to. During testing, please use the sfcode as "dcr-cert".
If you do not have any of these pre-requisites or if you have any questions, please contact our SDK sales support team.

Nielsen Measurement Opt-Out Implementation
As a global information and measurement leader, we are committed to protecting the privacy and security of the data we collect, process and use. Our digital measurement products are not used to identify the consumer in any way, but they help us and our clients measure and analyze how consumers engage with media across online, mobile and emerging technologies, and offer insights into consumer behavior.
When the user wants to opt in or opt out of Nielsen measurement, a new dynamic page (with content similar to http://secure-us.imrworldwide.com/nielsen_app_optout.html) should be displayed.
For more details, refer to Browser SDK API Reference - Browser Opt-Out Implementation and Nielsen Digital Privacy.
- Use getOptOutStatus (Browser) to retrieve the user’s current Opt-Out status.
After the website is ready to be sent for Nielsen Certification, please go through the Pre-Certification Checklist and ensure the webpage behaves as expected, before submitting to Nielsen.
