It is really very simple for you to select and work with the different User ID vendors that are compliant with Prebid.
Simply Select which ones you want to work with by moving to Global Settings - Programmatic Configurations, and press "Add a new User ID module". This will bring up a list of the different ID Vendors you can work with:
When selecting one of the ID Vendors, you get a chance to enter the Credentials (if needed). Some of the ID vendors does not require a specific ID to be used (It is generic), but some do, so you will have to take look at the prebid page, and see if you need to contact the vendor for credentials:
In order to utilize the specific Vendor in the call you can then change what you want to utilize in the Prebid parameters pages, either on a global or site. Press the Prebid Parameters button an scroll to the bottom, and you will find a section called User ID Modules:
Opening one of the modules will enable you with a few options:
- Enable User ID Module: Turn the module On/Off
- Storage: Opens up the settings for how you would like to handle the storage.
- Type: Local Storage or Cookie.
- Storage Time (days): How long do you want the user to stay registered.
- Time before refresh (seconds):
Select which UserID modules you would like to have turned on and they will now be running with your requests.
