# Show what changed between two versions

`GET /sites/{id}/diff`

## Request

- Base URL: `https://api.hypamoon.com/api/v1`
- URL: `https://api.hypamoon.com/api/v1/sites/{id}/diff`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://app.hypamoon.com/oauth/authorize`, token URL `https://api.hypamoon.com/oauth/token`, scopes: `sites:read`)

For each path, whether it was added, modified, removed or replaced between two versions of a site. Text files (html, css, js, json, txt, svg) get a unified diff; binary files (images, fonts) only their old and new size. Without to: the current version. Without from: the version before to (for a preview: the live version). Large diffs are left out (diff_omitted) to keep the response small.

## Path parameters

- `id` string, uuid, required

## Query parameters

- `from` string
- `to` string

## Response `200`
