Salesforce DMP has a standard Opt-out URL that can be called by our partners to execute the opt-out action for a user. A user can opt-out of tracking by the Salesforce DMP platform by visiting https://www.salesforce.com/products/marketing-cloud/sfmc/salesforce-dmp-consumer-choice/ and clicking on the "Opt-out" button.
https://consumer.krxd.net/consumer/optout is the standard DMP opt-out URL. When called directly, this URL will execute the Opt-out action for a user and it will return the following JSON response:
A user must allow cookies from Salesforce DMP in order to opt-out. Calling the DMP opt-out code (by clicking on an opt-out button placed on the client's page) will result in a persistent 'cookie' placed in the user’s web browser by Salesforce, identifying that user as being on the Salesforce DMP 'do not target' list. Taking this opt-out step won't prevent all tracking and targeting online, but it will ensure the user’s wishes are honored by all Salesforce DMP clients.
Note: If the user uses more than one computer, the process must be repeated for each one as this information is associated with a cookie unique to each machine.
DMP Cookie Status
To determine the tracking state of a user (opted-out vs. opted-in), a customer should call https://consumer.krxd.net/consumer/cookie_status to return one of the following JSON responses:
if the user has opted out of tracking by Salesforce DMP
if the user is opted-in to tracking by Salesforce DMP
