# Add Status Page Incident Update

> Post a progress update on an incident timeline

## Overview

Adds a message to an incident's timeline and moves the incident to the status you give. Subscribers and visitors see the update on the status page. Posting an update with status `resolved` also records the resolution time; [Resolve Status Page Incident](/api-reference/status-pages/resolve-incident) is a shortcut for that.

`POST /api/projects/{projectId}/status-pages/{statusPageId}/incidents/{id}/updates`

## Authentication

| Header | Required | Description |
| - | - | - |
| `X-API-Key` | Yes | Your API key (`Authorization: Bearer {jwt}` also works). API keys need the `read_write` scope. |
| `Content-Type` | Yes | `application/json` |

**Required access:** project admin. No `X-Project-ID` header is needed.

## Path parameters

| Parameter | Type | Description |
| - | - | - |
| `projectId` | UUID | The project |
| `statusPageId` | UUID | The status page |
| `id` | UUID | The incident |

## Request body

| Field | Type | Required | Description |
| - | - | - | - |
| `message` | string | Yes | 1-5000 characters |
