# Validate a site migration redirect map (old URL to new URL)

**Use case:** 

Paste your redirect map as 'old URL -> new URL' lines and check every pair after a site migration: one row per old URL with the full 301/302 chain, the real final URL and status, and EXPECTED_MISMATCH when it does not land where you planned. Catch wrong targets, chains and dead pages before Google does, then export to CSV.

## Input

```json
{
  "urls": [
    "http://apify.com -> https://apify.com/",
    "http://wikipedia.org -> https://www.wikipedia.org/",
    "http://github.com -> https://github.com/"
  ],
  "maxItems": 0,
  "maxRedirects": 10,
  "userAgent": "browser",
  "followMetaRefresh": true,
  "ignoreTrailingSlash": true,
  "ignoreQueryString": false,
  "maxConcurrency": 10,
  "requestTimeoutSecs": 15
}
```

## Output

```json
{
  "url": {
    "label": "Old URL",
    "format": "string"
  },
  "expectedUrl": {
    "label": "Expected",
    "format": "string"
  },
  "finalUrl": {
    "label": "Actually ends at",
    "format": "string"
  },
  "expectedMatch": {
    "label": "Match",
    "format": "boolean"
  },
  "redirectChain": {
    "label": "Chain",
    "format": "string"
  },
  "issues": {
    "label": "Issues",
    "format": "array"
  },
  "status": {
    "label": "Status",
    "format": "string"
  }
}
```

## About this Actor

This example demonstrates how to use [Bulk Redirect Checker: 301 Chains, Loops & Redirect Maps](https://apify.com/quanta1810/bulk-redirect-checker.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/quanta1810/bulk-redirect-checker.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
