# List Shared Connections

GET https://app.polytomic.com/api/connections/{parent_connection_id}/shared

Lists shared copies of a connection.

## Observed rate limits

You can use `rate_limit` to inspect observed rate limiting separately from
Connection health. A Connection can be healthy while Polytomic has an active
rate-limit marker. Shared Connections combine observations recorded for their
own ID and their root Connection. Observations recorded only for another shared
copy are not included.

When these observed periods overlap or touch, `limited_since` reflects the start
of the continuous period and `expires_at` reflects its latest expiry. An expired
period separated from the active period by a gap does not extend that start.

> ⚠️ Observation, not a capacity guarantee
>
> An active marker does not mean every endpoint or sync is blocked. No active
> marker does not guarantee that the upstream service has capacity. The marker
> expiry can be extended and is not a promised provider reset or exact retry time.

If any required lookup is unavailable, `rate_limit` is `null`. This does not change
`status` or `status_error`, and the Connection response is still returned.

- `error` (string, optional) — Error message.
- `status` (string, optional) — Status text.

### 403 Forbidden Error

Forbidden

- `key` (string, optional)

## Types

### V2ConnectionResponseSchema

- `api_calls_last_24_hours` (integer, optional, nullable) — API calls made to service in the last 24h (supported integrations only).
- `configuration` (map from string to any, optional, nullable)
- `created_at` (datetime, optional)
- `created_by` (OutputActor, optional)
- `id` (string, optional)
- `name` (string, optional)
- `organization_id` (string, optional)
- `parent_connection_id` (string, optional) — For shared connections, the ID of the parent connection.
- `policies` (list of string, optional)
- `rate_limit` (V2ConnectionResponseSchemaRateLimit, optional, nullable) — Observed connection-wide rate limiting, independent of connection health. Null when any required lookup is unavailable. Shared connections combine their own marker with their root connection's marker.
- `saved` (boolean, optional)
- `status` (string, optional)
- `status_error` (string, optional)
- `type` (V2ConnectionTypeSchema, optional)
- `updated_at` (datetime, optional)
- `updated_by` (OutputActor, optional)

### OutputActor

- `id` (string, optional)
- `name` (string, optional)
- `type` (string, optional)

### V2ConnectionResponseSchemaRateLimit

Observed connection-wide rate limiting, independent of connection health. Null when any required lookup is unavailable. Shared connections combine their own marker with their root connection's marker.

- `currently_limited` (boolean, optional) — Whether Polytomic has an unexpired connection-wide rate-limit marker. False means no active observed limit, not guaranteed upstream capacity.
- `expires_at` (datetime, optional, nullable) — Marker expiry unless extended. Not a promised provider reset or exact retry time. Null when no active marker exists.
- `limited_since` (datetime, optional, nullable) — Start of the continuous rate-limited period. Null when no active marker exists.

### V2ConnectionTypeSchema

- `id` (string, optional)
- `logo_dark_url` (string, optional)
- `logo_url` (string, optional)
- `name` (string, optional)
- `operations` (list of string, optional, nullable)
