User ID module

Last edited: 2024/12/09

The User ID module supports various methods of establishing pseudonymous IDs for users, which significantly increases the value of header bidding. Instead of multiple exchanges syncing IDs with numerous demand sources, you can integrate with several different ID schemes, streamlining the process.

See Prebid documentation on User ID modules: link

You can use:

• Own accounts - meaning that you have direct contact signed with a given user ID module provider

• Yieldbird accounts - meaning you do not have a direct contract signed with an ID module provider, and want to use Yieldbird’s contract.

Good practice: User ID providers are paid for by the buy side, so using Yieldbird accounts is completely free of charge. This can save you a lot of time spent on the legal process of signing a direct contract with the provider.

Is there privacy compliance with Prebid’s User ID Module?

When combined with the Consent Management module (Consent management), privacy regulations are enforced by User ID module as follows:

• The module verifies the GDPR consent string.
• If the consent string is absent or the user has not agreed to Purpose 1 (local storage):
• No calls are made to external user ID vendors.
• No data is stored in cookies or HTML5 local storage.

Adding a User ID modules

If you can’t find the User ID that you want to add on the list, please let us know!

We can add any User ID that is currently compatible with Prebid. Simply ask your Customer Success Manager for the User ID you need, and we will add it in the next development sprint.

See the list of User ID sub-modules that can be added in the Prebid.org documentation.

Please mark that in case you need Yieldbird to provide you with the account, the process will take longer as we will have to sign a contract with the requested User ID provider.

The list of currently integrated User Id sub-modules: see list.

Adding User ID on Workspace level

First, you must add the User ID module to the workspace and define its basic parameters. To do that:

1. Go to Setup > Modules > User IDs
2. When you want to use Own account (meaning you do have a direct contract signed with the ID module provider):
1. Go to section Own user ID accounts
2. Select the User ID adapter from the dropdown list of available adapters and click Add.
3. Fill in the required parameters and click Confirm. Optional parameters are available to view and fill in when you click More.
3. When you want to use Yieldbird’s account (meaning that you do not have a direct contract signed with the ID module provider):
1. Go to section Yieldbird user ID accounts
2. Select the User ID adapter from the dropdown list of available adapters and click Add

Since all required parameters for Yieldbird accounts have already been added to the configuration, you can use the User ID immediately.
4. Click Save at the bottom

To use the User ID on your inventory, you must activate it on specific Domains first (see paragraph below).

Activating User ID on Domain level

Then, you must select the domains on which you want the module to work. To do that:

1. Go to Prebid Stack > Inventory > Domains > select the domain you want to edit
2. Go to the Module connectors section, and toggle it on.
3. Select the checkbox next to the User ID you want to activate on this domain and click Save.
