# Destination Platforms

Returns the available destination platform identifiers used by [PREDUPE](https://docs.repdata.com/research-defender/guides/02-predupe). Call this server-side with your private key.

Use the returned `destination_platform_id` (and the platform's internal survey number) when activating PREDUPE on a SEARCH call. For Research Desk as the destination platform, the survey number is the `ProjectUd`.


## OpenAPI

````yaml GET /api/v3/respondents/destination_platforms/{private_key}
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.
