# Get Responses

> List a study's responses with answers and summaries, paginated

<Warning>
  This versioned endpoint replaces the old
  [`GET /api/public/responses/{link_id}`](/get-responses) endpoint, which is
  deprecated starting **August 1, 2026** — migrate before then.
</Warning>


## OpenAPI

````yaml api-v2/openapi.yaml GET /api/public/v1/responses/{linkId}
openapi: 3.0.3
info:
  title: Listen Labs Public API v2
  version: 2.0.0
  description: >-
    Create and launch studies, and retrieve response data programmatically.
    Authenticated with an `x-api-key` header; the key is scoped to a single
    organization.


    Cross-field rules that JSON Schema cannot express (screening placement,
    min/maxSelect coupling, unique externalIds, reference resolution,
    exclusiveOption placement) are described on the relevant schemas and
    enforced by the server (returned as 400 responses).


    All error responses share one JSON envelope: `error` (human-readable
    message, may change) and `code` (stable machine-readable identifier; branch
    on this). 400 responses may also carry `issues` with per-field schema
    violations. The possible codes for each response are listed in its
    description.
