# ChangeDetection.io Web page monitoring and notifications API
REST API for managing Page watches, Group tags, and Notifications.
changedetection.io can be driven by its built in simple API, in the examples below you will also find `curl` command line and `python` examples to help you get started faster.
## Where to find my API key?
The API key can be easily found under the **SETTINGS** then **API** tab of changedetection.io dashboard.
Simply click the API key to automatically copy it to your clipboard.
![Where to find the API key](./where-to-get-api-key.jpeg)
## Connection URL
The API can be found at `/api/v1/`, so for example if you run changedetection.io locally on port 5000, then URL would be `http://localhost:5000/api/v1/watch/cc0cfffa-f449-477b-83ea-0caafd1dc091/history`.
If you are using the hosted/subscription version of changedetection.io, then the URL is based on your login URL, for example:
`https://<your login url>/api/v1/watch/cc0cfffa-f449-477b-83ea-0caafd1dc091/history`
## Authentication
Almost all API requests require some authentication, this is provided as an **API Key** in the header of the HTTP request.
For example: `x-api-key: YOUR_API_KEY`
version: 0.1.6

- name: Watch Management
description: |
Core functionality for managing web page monitors. Create, retrieve, update, and delete individual watches.
Each watch represents a single URL being monitored for changes, with configurable settings for check intervals,
notification preferences, and content filtering options.
- name: Watch History
description: |
Get a list of timestamps of all changes detected for a watch.
- name: Snapshots
description: |
Retrieve individual text snapshot of monitored content according to the `timestamp`. The text snapshot is the HTML
to Text at page check time.
Set the query argument `html` to any value to retrieve the last HTML fetched, the system only keeps the last two
(2) HTML files fetched.
Use the Watch History API endpoint to get a list of timestamps to pass to this query.
- name: Favicon
description: |
Retrieve favicon images associated with monitored web pages. These are used in the dashboard interface
to visually identify different watches in your monitoring list.
- name: Group / Tag Management
description: |
Organize your watches using tags and groups. Tags (also known as Groups) allow you to categorize monitors, set group-wide
notification preferences, and perform bulk operations like mass rechecking or status changes across
multiple related watches.
- name: Notifications
description: |
Configure global notification endpoints that can be used across all your watches. Supports various
notification services including email, Discord, Slack, webhooks, and many other popular platforms.
These settings serve as defaults that can be overridden at the individual watch or tag level.
The notification syntax uses [https://github.com/caronc/apprise](https://github.com/caronc/apprise).
- name: Search
description: |
Search and filter your watches by URL patterns, titles, or tags. Useful for quickly finding specific
monitors in large collections or identifying watches that match certain criteria.
- name: Import
description: |
Bulk import multiple URLs for monitoring. Accepts plain text lists of URLs and can automatically
apply tags, proxy settings, and other configurations to all imported watches simultaneously.
- name: System Information
description: |
Retrieve system status and statistics about your changedetection.io instance, including total watch
counts, uptime information, and version details.

get:
operationId: getWatchHistoryDiff
tags: [Watch History]
summary: Get the difference between two snapshots
description: |
Generate a difference (comparison) between two historical snapshots of a web page change monitor (watch).
This endpoint compares content between two points in time and returns the differences in your chosen format.
Perfect for reviewing what changed between specific versions or comparing recent changes.
**Timestamp Keywords:**
- Use `'latest'` for the most recent snapshot (to_timestamp)
- Use `'previous'` for the second-most-recent snapshot (from_timestamp)
- Or use specific Unix timestamps from the watch history
**Format Options:**
- `text` (default): Plain text with (removed) and (added) prefixes
- `html`: HTML format with (removed) and (added) text
- `htmlcolor`: Rich HTML with colored highlights (green for additions, red for deletions)
**Word-Level Diffing:**
- Enable word-level granularity with `word_diff=true` for detailed inline comparisons
- Disable with `word_diff=false` for line-level comparisons only (default false/off, line-level mode by default)
**Raw Diff Output:**
- Use `no_markup=true` to get raw diff content without any formatting applied
- Returns content with placeholders for opening/closing tags of changes
- Allows you to implement your own custom colorisation or formatting
- Skips all HTML color application and service tweaks (added text, html color tags, etc)

You can pass ANY watch configuration field as query parameters to apply settings to all imported watches.
All parameters from the Watch schema are supported (processor, fetch_backend, notification_urls, etc.).
**Special Parameters:**
- `tag` / `tag_uuids` - Assign tags to imported watches
- `proxy` - Use specific proxy for imported watches
- `dedupe` - Skip duplicate URLs (default: true)
**Type Conversion:**
- Booleans: `true`, `false`, `1`, `0`, `yes`, `no`
- Arrays: Comma-separated or JSON format (`[item1,item2]`)
- Objects: JSON format (`{"key":"value"}`)
- Numbers: Parsed as int or float
