# DUPLICATE_DETAILS

Returns each duplicate detail code with its description. These codes appear in the `dupes_details` array of a SEARCH response when you send `dupe_details=1`: `01` IP address, `02` cookie, `03` Panel\_ID, and `04` hashed email.


## OpenAPI

````yaml GET /api/v2/respondents/dupe_details/
openapi: 3.0.3
info:
  title: Research Defender API
  version: 1.0.0
  description: >-
    Research Defender protects survey data quality through digital
    fingerprinting, duplication detection, and open-end text analysis. This
    reference covers the **SEARCH**, **REVIEW**, and **PREDUPE** products.


    > ACTIVITY and VERIFY are hosted on a separate domain (resdefio.com) and are
    documented separately.


    ## Authentication


    Client-side calls (SEARCH, REVIEW, GETTOKEN) use your **publishable key** in
    the URL path. Server-side lookups (destination_platforms) use your **private
    key**. For enhanced protection, use V3 server-to-server tokens (GETTOKEN) or
    V4 Hashed Validation.
