# List member enrollment history log

GET https://api.vitablehealth.com/v1/members/{member_id}/enrollment-audits

Lists enrollment, termination, and reissue audits for enrollments visible to the caller. Entries are ordered newest first with stable paging. Organization callers see only enrollments in their book. A member not visible to the caller returns a 404 before pagination is validated.

Reference: https://developer.vitablehealth.com/api/members/list-member-enrollment-audits

## 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_*)

### Query parameters

- `limit` (integer, optional, default: 20) — Items per page (default: 20, max: 100)
- `page` (integer, optional, default: 1) — Page number (default: 1)

### 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`.
