# Link alert
> Links an alert configuration to an existing webhook.
### Overview
Adds an alert configuration to an existing webhook's subscription list. Idempotent — if the alert is already linked, the response is `200` with no change.
Use this when you want to add alerts one at a time after creation, rather than updating the full `alertIds` list via [`PUT /v2/api/webhooks/{id}`](/v2/api-reference/put-webhooks-id).
**Rate limit:** 4 req/s · 20/min · 600/hr · 14,400/day
### Endpoint
`POST /v2/api/webhooks/{id}/link-alert`
### Path parameters
Webhook ID.
### Request body
```json theme={null}
{
"alertId": 103
}
```

| alertId | integer | Yes | Alert configuration ID to link (from [`GET /v2/api/companies/{id}/alerts`](/v2/api-reference/get-companies-id-alerts)) |

info:
title: Telemax External API (V2)
version: '2026-04-14'
description: >
Telemax External API — fleet telemetry, vehicle commands, and integrations.
**Base URL:** `https://api.telemax.com.au`
**Authentication:** All routes require a `Bearer` JWT unless marked
`[AllowAnonymous]`.
Obtain tokens via `POST /v2/api/authentication/token/api-key`.
**RESTful architecture:** V2 uses standard HTTP methods (GET, POST, PUT,
DELETE) with
resource-based routes and consistent pagination via `page` and `pageSize`
query parameters.
**API versioning:** All responses will include an `X-API-Version` header
containing the
date-based version string (e.g. `2026-04-28`). See the
[Changelog](/v2/changelog) for
the deprecation policy and version history.
For full documentation including error handling, pagination, and known field
quirks, see [docs.telemax.com.au](https://docs.telemax.com.au).

**Lifetime:** ~24 hours (86,399 seconds). Cache the token and reuse it.
Re-authenticate 5 minutes before expiry.

and may restrict
access to a vehicle allowlist and/or action set (see token claims).
**No refresh endpoint** — re-authenticate with your API key when the
token expires.
