# List Groups

`GET /api/v1/groups`

Returns all groups for your organization, including associated websites. Requires a global API key. **Partner integrations** may pass `external_id` as a query parameter to find the Athena group mapped to a partner-supplied identifier.

## Query parameters

- `external_id` string

## Response `200`

Successful response with list of groups. Partner responses include an `externalId` field on each item (string or `null`); direct-customer responses omit the field entirely.

    - `externalId` string, nullable — **Partner-only.** The partner-supplied identifier mapped to this group. Only present on responses to callers whose organization is flagged as a partner. Direct-customer responses omit the field entirely. `null` indicates no mapping exists for this group.

## Other responses

- `403` — Forbidden - Requires a global API key, or (when using the `external_id` filter) a partner API key.
- `500` — Internal server error
