DSPs

As a demand-side platform (DSP, media-buying platform), you can facilitate identity strategies that leverage European Unified ID (EUID) to facilitate the following:

• First-party data activation for advertisers
• Inventory monetization for publishers

Learn about benefits, workflow, documentation, and other resources for DSPs adopting EUID, as well as instructions for getting started.

Benefits of EUID for DSPs

Here are just some of the intended benefits for DSPs using EUID. You can:

• Upgrade identity resolution with an authenticated ID.
• Reduce dependency on third-party cookies.
• Execute omnichannel and cross-device frequency management and suppression.
• Facilitate first-party data activation with a more privacy-conscious standard for ID encryption.
• Aim to develop future-proof models with deterministic data.
• Maintain addressable audience targeting.
• Offer opt-out, with the goal of improving consumer privacy controls.
• More accurately measure campaigns with or without third-party cookies.

Workflow for DSPs

The following steps provide a high-level outline of the workflow intended for DSPs that transact on EUIDs in the bidstream.

The following processes occur in the background:

• The advertiser and/or data provider passes first-party and third-party audience segments to the DSP.
• The DSP syncs with the EUID Operator to receive decryption keys.
• The DSP listens to opt-out requests from the EUID Operator.

The following steps occur for each bid/ad impression:

1. A bid request is passed into the bidstream with the EUID token.
2. The DSP receives the bid request with the EUID token from the bidstream.
3. The DSP:
   • Decrypts the EUID token into a raw EUID.
   • Checks to see if the user opted out and, if so, does not bid.
   • Matches the raw EUID to an audience segment.
4. The DSP sends a bid response to the bidstream with the EUID token.

Getting Started

To get started, follow these steps:

1. Request access to EUID by filling out the form on the Request Access page.

2. Implement a webhook to receive EUID opt-out information, and share the webhook with the EUID administrator.

3. Confirm that you are receiving the opt-out feed via the webhook.

   When the webhook is in place, you'll receive your credentials (see EUID Credentials).

4. Decide which implementation option you want to use.

5. If you're using an SDK, download the SDK. Refer to the applicable SDK guide.

6. Follow the instructions in the implementation guide for the option you chose.

   note

   Be sure to encrypt request messages to EUID. For details, see Encrypting Requests and Decrypting Responses.

7. (Conditional) If you want to implement a CRM onboarding solution, request a separate set of credentials for the data provider workflow. See EUID Credentials.

8. Test.

9. Go live.
