# List a contact's topic subscriptions

`GET /contacts/{id}/topics`

## Request

- Base URL: `https://www.unitpost.com/api/v1`
- URL: `https://www.unitpost.com/api/v1/contacts/{id}/topics`
- Auth: HTTP bearer

Retrieve a contact's effective subscription state for every active topic, cursor-paginated. Each row resolves the contact's explicit preference against the topic's `default_opt_in`, so `subscribed` is always the answer to "would this contact receive a campaign scoped to this topic?". Change a preference with [Set a contact's topic preference](#post-contacts-id-topics). Requires the `topics:read` capability.

## Query parameters

- `limit` integer
- `after` string
- `before` string

## Response `200`
