## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## App Release & Customer Reaction Monitor

Answer the product question that a raw app-review scraper cannot: **did this release improve customer experience, or introduce a regression?**

The Actor joins structured release records with dated review records. When at least three reviews carry the exact app version, version attribution wins; otherwise a configurable before/after date window is used.

### Each release report includes

- review counts before and after
- average rating before, after, and the change
- sentiment direction
- emerging, resolved, and recurring complaint categories
- regression signals and issue-spike flag
- `IMPROVED`, `REGRESSED`, `MIXED`, `STABLE`, or `INSUFFICIENT_DATA` conclusion

### Composition-first input

Paste records or provide Apify dataset IDs. This Actor intentionally does not scrape Apple App Store or Google Play itself, so it can work with different upstream collectors and does not depend on brittle authenticated/private endpoints.

### Quick start

```json
{
  "appName": "Acme Mobile",
  "releases": [{ "version": "2.0.0", "releaseDate": "2026-08-01", "releaseNotes": "New sync engine" }],
  "reviews": [
    { "text": "Stable and fast.", "rating": 5, "date": "2026-07-28", "version": "1.9.0" },
    { "text": "Crashes after the update.", "rating": 1, "date": "2026-08-03", "version": "2.0.0" }
  ]
}
```

### Pricing

The intended pricing is pay per release analyzed, with platform usage included. The run summary is free. Exact current pricing appears on the Store page and charge limits are respected.

### Limitations

At least three reviews on both sides are required for a directional conclusion. Version labels and review dates come from upstream data and are not independently verified. Keyword-based issue categories are transparent but may miss synonyms, sarcasm, and non-English feedback. Correlation around a release is not proof that the release caused the reaction. Always inspect underlying reviews before shipping a rollback or product decision.

Reviewer identity is ignored; no personal-data profiling, outreach, private scraping, credentials, or CAPTCHA bypass are used.

# Actor input Schema

## `appName` (type: `string`):

Label added to every release report and summary row.

## `releases` (type: `array`):

Each release needs version and releaseDate.

## `releaseDatasetId` (type: `string`):

Read releases from an accessible Apify dataset when pasted releases are absent.

## `reviews` (type: `array`):

Each review needs text, rating 0–5, and date. Version improves attribution.

## `reviewDatasetId` (type: `string`):

Read reviews from an accessible Apify dataset when pasted reviews are absent.

## `windowDays` (type: `integer`):

Used when too few reviews carry the release version.

## `maxReviews` (type: `integer`):

Hard cap on review records read in one run.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,egeusta/app-release-customer-reaction-monitor"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
