All calls to the Match endpoint or the Lookup endpoint return a "person document", which contains information about an individual, such as the RampID.

Example

{
  "person": {
    "anonymousAbilitec": {
      "anonymousConsumerLink": "XiT001sgRRky74xZ6NrpSsF6z2ucg6TeV8rISolIhOMe-R94lh47QP2xuVITxFm6otlyrB"
    }
  }
}
