# List Dependents

GET https://api.vitablehealth.com/v1/members/{member_id}/dependents

Lists a member's active legal dependents — name, relationship, date of birth, age, and sex at birth. Access is scoped to the authenticated principal; a member not visible to the caller returns a 404.

Reference: https://developer.vitablehealth.com/api/members/list-dependents

## Authentication

- `Authorization` header (bearer token, required) — API Key or Access Token authentication using Bearer token in Authorization header. API keys use the vit_apk_ prefix, access tokens use the vit_at_ prefix.

## Servers

- `https://api.vitablehealth.com` (Production, default)
- `https://api.uat.vitablehealth.com` (UAT)

## Request

### Path parameters

- `member_id` (string, required) — Unique member identifier (mbr_*)

### Headers

- `X-Vitable-Organization` (string, optional) — Organization to act as for this request (e.g. `org_SGVsbG8gV29ybGQ`). Optional when your credentials reach a single organization. Required when they reach several — omitting it then returns 400 `organization_required`. A malformed value returns 400 `invalid_organization_header`, and naming an organization you do not have access to returns 403 `organization_access_denied`.

## Response

### 200

- `data` (list of MemberLegalDependent, required) — The member's legal dependents.
