## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## 📱✅ WhatsApp Number Validator

**Instantly verify whether any phone number is registered on WhatsApp.** Paste one number or thousands, hit **Start**, and watch clean, structured results stream in live. Perfect for cleaning lead lists before a campaign, confirming customer reachability, or de-duplicating a CRM.

> Powered by a dedicated WhatsApp validation engine — no WhatsApp account, login, or device required.

---

### 🌟 Why Choose This Actor?

| | |
|---|---|
| 🚀 **Bulk-first** | Validate a whole list in one run — not one number at a time. |
| ⚡ **Real-time** | Every result is pushed to the dataset the instant it's decided. A crash never loses completed work. |
| 🌐 **Smart proxy escalation** | Starts **direct** for speed; auto-falls back to **datacenter** then **residential** proxies only if blocked. |
| 🧾 **Clean output** | Structured JSON ready for Sheets, CRMs, and pipelines. |
| 🔌 **API & MCP ready** | Trigger from cURL, Make, n8n, or any HTTP client. |
| 🎯 **Zero setup** | No API keys or configuration required to get started. |

---

### ✨ Key Features

- ✅ Check if a phone number is **active on WhatsApp**
- 🌍 **Global coverage** — works with any country code
- 📞 **Bulk validation** — paste many numbers at once
- 📊 **Three dataset views** — All Results, Registered, Full Details
- 🔁 **Automatic retries** with graceful error records
- 🕒 **Timestamps & metadata** on every record (toggleable)

---

### 📥 Input

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `phoneNumbers` | array | ✅ | Bulk list of numbers (digits + country code). |
| `phoneNumber` | string | — | Optional single number, merged with the bulk list. |
| `proxyConfiguration` | object | — | Proxy settings. Default: direct (no proxy). |
| `concurrency` | integer | — | Parallel checks (1–10, default 3). |
| `rpm` | integer | — | Max checks per minute (default 5). |
| `maxRetries` | integer | — | Retries per number (default 3). |
| `includeMeta` | boolean | — | Add `meta` block (default true). |
| `includeTimestamp` | boolean | — | Add `timestamp` (default true). |

#### Example input

```json
{
  "phoneNumbers": ["212612542343", "15005550000", "447911123456"],
  "proxyConfiguration": { "useApifyProxy": false }
}
````

> **Tip:** include the full country code and digits only. `+`, spaces, dashes and brackets are cleaned automatically.

***

### 📤 Output

Each validated number produces one record:

```json
{
  "phoneNumber": "212612542343",
  "isValid": true,
  "exists": true,
  "timestamp": "2026-06-17T09:48:19.944292+00:00",
  "meta": {
    "instance": "wavalidator.com",
    "source": "live"
  },
  "status": "success"
}
```

| Field | Type | Description |
|-------|------|-------------|
| `phoneNumber` | string | The number you validated (normalized digits). |
| `isValid` | boolean | `true` if registered on WhatsApp. |
| `exists` | boolean | Same as `isValid` (kept for compatibility). |
| `timestamp` | string | ISO-8601 time of the check. |
| `meta.instance` | string | Validation engine instance. |
| `meta.source` | string | Source of the validation (`live`). |
| `status` | string | `success`, or `error` on a failed check. |
| `error` | string | Present only when `status` is `error`. |

### 🤖 Use via API

```bash
curl -X POST "https://api.apify.com/v2/acts/<ACTOR_ID>/run-sync-get-dataset-items?token=$APIFY_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{ "phoneNumbers": ["212612542343", "447911123456"] }'
```

***

### 💡 Best Use Cases

- 🎯 **Marketing** — clean WhatsApp campaign lists before sending.
- 🛡️ **Verification** — confirm customers have an active WhatsApp.
- 🧹 **Data cleaning** — drop unreachable numbers from your database.
- 🔌 **CRM enrichment** — flag which leads are reachable on WhatsApp.

***

### 💰 Pricing

This Actor uses **Pay-Per-Event**. The primary event is **`number-checked`**, billed once per number validated. You also pay standard Apify platform usage (compute). Bulk runs are efficient — you only pay for the numbers you check.

***

### ❓ FAQ

**Do I need a WhatsApp account or API key?**
No. It works out of the box.

**Does it message the number?**
No. Validation is passive — the target person is never contacted or notified.

**Why did a number come back as an error?**
Transient network/engine hiccups can cause an occasional `error` status. Re-run those numbers — the Actor always returns the successful ones regardless.

**Can I check thousands of numbers?**
Yes. Add them all to `phoneNumbers`. Results stream in live as they complete.

***

### ⚖️ Cautions / Legal

- Only validates **publicly determinable** WhatsApp registration status — no private data, messages, or profile content is accessed.
- You are responsible for compliance with GDPR, CCPA, anti-spam laws, and WhatsApp's Terms when using the results.

# Actor input Schema

## `phoneNumbers` (type: `array`):

Add one or more phone numbers to validate. Include the full country code and digits only — spaces, +, dashes and brackets are cleaned automatically. Examples: 212612542343, 12125551234, 447700900123.

## `proxyConfiguration` (type: `object`):

Runs direct (no proxy) by default for best speed. If the validation engine blocks the connection, the Actor automatically escalates to a datacenter proxy and then to a residential proxy — and stays there for the rest of the run.

## `concurrency` (type: `integer`):

How many numbers to validate at the same time.

## `rpm` (type: `integer`):

Maximum validation submissions per minute. Keep modest to stay friendly with the validation engine.

## `maxRetries` (type: `integer`):

How many times to retry a number before recording it as an error.

## `includeMeta` (type: `boolean`):

Add a 'meta' object (instance + source) to each result.

## `includeTimestamp` (type: `boolean`):

Add an ISO-8601 'timestamp' to each result.

## Actor input object example

```json
{
  "phoneNumbers": [
    "212612542343",
