No, Nielsen does not need to access your application for you to use the APIs. Nielsen will provide you with all the information necessary for you to successfully integrate and test the Nielsen APIs into your application.
Proper crediting instructions will be outlined in your terms of use agreement.
An API key is a unique identifier that tells Nielsen API Portal which user is initiating a request. The API key is used to authenticate a user/application.
Yes, for testing users are limited to a small number of calls per second and per hour. For commercial users, please refer to the terms of your agreement or look within the subscription section of the Nielsen API Portal.
Each API has a testing interface where you can see the parameters and test output. This feature is only available to registered users. To access, within the Nielsen API Portal navigate to the Products page and select the API you are interested in. Select the API Explorer Tab and expand the details. If you would like to test the API in your application, contact our commercial team.
