## Description

List Arlo registration records with embedded attendee/contact detail, optionally filtered by event. Run **List Events** first to obtain an `eventId`. Results are paged (see `limit`/`skip`); if the page comes back full, call again with a higher `skip` for more. Use `fields` to shrink the response — registration lists can be very large (thousands of records) and each record is verbose. Example: call with `eventId: "4"`, `limit: 50` to get up to 50 registrations for event 4 with `RegistrationID`, `Status`, `Contact`. [See the documentation](https://developer.arlo.co/doc/api/2012-02-01/auth/resources/registrations#collection-httpget).

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `eventId` | `string` | No | Optional. The integer ID of an event to list registrations for. Run List Events to find the event ID. |
| `status` | `string` | No | Optional. Filter registrations by status. |
| `limit` | `integer` | No | Maximum number of records to return per page. Min 1, max 1000. Defaults to 100. If the response returns exactly this many records, more may exist — call again with a higher skip to page through. |
| `skip` | `integer` | No | Number of records to skip, for paging past the first page. Defaults to 0 (start at the beginning). Set to limit from the previous call to fetch the next page, 2 * limit for the page after that, and so on. |
| `fields` | `string[]` | No | Optional. Return only these top-level fields per registration (e.g. ["RegistrationID", "Status", "Contact"]) instead of the full record. Strongly recommended for large registration lists. |
