+### AkamaiDAPId
+
+The Akamai Data Activation Platform (DAP) is a privacy-first system that protects end-user privacy by only allowing them to be targeted as part of a larger cohort.  DAP views hiding individuals in large cohorts as the best mechanism to prevent unauthorized tracking.
+
+The integration of DAP into Prebid.JS consists of creating a UserID plugin that interacts with the DAP API.  The UserID module tokenizes the end-user identity into an ephemeral, secure pseudonymization called a dapId.  The dapId is then supplied to the bid-stream where the SSP partner looks up cohort membership for that token, and supplies the cohorts to the rest of the bid-stream.
+
+In this system, no end-user identifier is supplied to the bid-stream, only cohorts.  This is a foundational privacy principal DAP is built upon.
+
+#### AkamaiDAPId Configuration
+
+First, make sure to add the DAP submodule to your Prebid.js package with:
+
+```
+gulp build --modules=akamaiDAPId,userId
+```
+
+The following configuration parameters are available:
+
+```javascript
+pbjs.setConfig({
+  userSync: {
+    userIds: [{
+      name: 'akamaiDAPId',
+      params: {
+        apiHostname: '<see your Akamai account rep>',
+        domain: 'your-domain.com',
+        type: 'email' | 'mobile' | ... | 'dap-signature:1.0.0'
+      },
+    }],
+    auctionDelay: 50             // 50ms maximum auction delay, applies to all userId modules
+  }
+});
+```
+Contact amishra@akamai.com for apiHostname.
