res = requests.get(
    "https://app.booksbyinstant.com/api/integrator/v1/customers/01900000-0000-7000-8000-000000000000/members/01900000-0000-7000-8000-000000000000/tokens",

    },
)
data = res.json()
```

## Authorization

- Bearer token `live_<100 hex>`: `Authorization: Bearer <secret>`. A 401 answers `WWW-Authenticate: Bearer realm="instant-integrator-api"`.

## Path parameters

- `id` (string · uuid; required): The customer's id.
- `memberId` (string · uuid; required): The member's id.

## Responses

### 200

The tokens, newest first.

`application/json`: object

- `tokens` (array of object; required)
  - `id` (string · uuid; required): The token's id.
  - `hint` (string; required; matches `^[a-z]+_m_…[0-9a-f]{4}$`): The secret's prefix, … and its last four hex characters, to tell tokens apart.
  - `status` (string; required; one of `active`, `expired`, `revoked`): active until the token expires or is revoked; neither one works again.
  - `createdAt` (string · date-time; required): When the token was issued. ISO 8601 in UTC with milliseconds, such as 2026-11-06T10:00:00.000Z.
  - `expiresAt` (string · date-time or null; required): When the token stops working, or null when it works until it is revoked. ISO 8601 in UTC with milliseconds, such as 2026-11-06T10:00:00.000Z.
  - `revokedAt` (string · date-time or null; required): When the token was revoked, or null. ISO 8601 in UTC with milliseconds, such as 2026-11-06T10:00:00.000Z.
  - `revokedReason` (string or null; required; one of `integrator`, `deactivated`, `operator`): Why it was revoked: integrator through this API, deactivated when the member was deactivated, operator by the people running Instant. Null unless revoked.
  - `lastUsedAt` (string · date-time or null; required): When the token was last used, accurate to 5 minutes, or null when it never was. ISO 8601 in UTC with milliseconds, such as 2026-11-06T10:00:00.000Z.

Example, built from the schema:

```json
{
  "tokens": [
    {
      "id": "01900000-0000-7000-8000-000000000000",
      "hint": "string",
      "status": "active",
      "createdAt": "2026-01-15T09:30:00.000Z",
      "expiresAt": "2026-01-15T09:30:00.000Z",
      "revokedAt": "2026-01-15T09:30:00.000Z",
      "revokedReason": "integrator",
      "lastUsedAt": "2026-01-15T09:30:00.000Z"
    }
  ]
}
```

### 401

The credential is missing, malformed, unknown, revoked or rotated, or its integrator is disabled. All of these answer the same way.

Headers:

- `WWW-Authenticate` (string): Bearer realm="instant-integrator-api"

`application/json`: object; `Error`

Every answer that is not a success.

- `error` (string; required): Instant's sentence for people. A 4xx keeps the refusal's own sentence; a 5xx always says "Instant is temporarily unavailable. Please try again shortly."
- `code` (string; required): Stable, and what a caller branches on: VALIDATION_ERROR (400), UNAUTHENTICATED (401), FORBIDDEN (403), NOT_FOUND (404), CONFLICT (409), LIMIT_EXCEEDED (413), UNSUPPORTED_MEDIA_TYPE (415), UNREADABLE_FILE (422), RATE_LIMITED (429) and UNAVAILABLE (5xx). More codes may be added; treat one you do not know by its status.
- `retryAfter` (integer; at least `1`): Seconds to wait before retrying, also sent as the `Retry-After` header. Present only when there is a wait, as on a 429.
- `existingId` (string · uuid): On a 409 that names the object already there, such as a customer with that reference: its id.

Example, built from the schema:

```json
{
  "error": "string",
  "code": "VALIDATION_ERROR",
  "retryAfter": 1,
  "existingId": "01900000-0000-7000-8000-000000000000"
}
```

### 404

`id` or `memberId` name nothing this caller can see.

`application/json`: the `Error` object, as in 401.

### 5XX

Instant is temporarily unavailable. Retry later, with backoff.

`application/json`: the `Error` object, as in 401.
