UID2 Overview for DSPs
Enable data strategies with a more durable identifier.
sidebarDSPs

import Link from '@docusaurus/Link';

As a demand-side platform (DSP, media-buying platform), you can facilitate identity strategies that leverage Unified ID 2.0 (UID2) 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 UID2, as well as instructions for getting started.

:::note If you want access in the left sidebar to the full set of UID2 documentation, see Unified ID 2.0 Overview. :::

Benefits of UID2 for DSPs

Here are just some of the intended benefits for DSPs using UID2. 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 UID2s in the bid stream.

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 UID2 Operator to receive decryption keys.
  • The DSP listens to opt-out requests from the UID2 Operator.

The following steps occur for each bid/ad impression:

  1. A bid request is passed into the bid stream with the UID2 token.
  2. The DSP receives the bid request with the UID2 token from the bid stream.
  3. The DSP:
    • Decrypts the UID2 token into a raw UID2.
    • Checks to see if the user opted out and, if so, does not bid.
    • Matches the raw UID2 to an audience segment.
  4. The DSP sends a bid response to the bid stream with the UID2 token.

Buy-Side Workflow

Getting Started

To get started, follow these steps:

  1. Request access to UID2 by filling out the form on the Request Access page.

  2. Implement a webhook to receive UID2 opt-out information, and share the webhook with the UID2 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 UID2 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 UID2. 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 UID2 Credentials.

  8. Test.

  9. Go live.
