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 Validator — Bulk Number Check Validate whether phone numbers have active WhatsApp accounts. Submit a list of phone numbers and get back per-number results showing WhatsApp status, WhatsApp ID, and normalized E.164 format. **Requires a [Whapi.Cloud](https://whapi.cloud) API key** (free tier available). ### Prerequisites 1. Sign up at [whapi.cloud](https://whapi.cloud) 2. Create a channel (connect a WhatsApp number) 3. Copy your API key from the channel settings 4. Paste it into the `whapiApiKey` input field when running this actor ### Quick Start ```json { "phoneNumbers": ["+15550100", "+442079460000", "5550199"], "defaultCountryCode": "US", "whapiApiKey": "YOUR_WHAPI_CLOUD_API_KEY" } ```` > Phone numbers in this example use ITU-reserved fictional ranges (`+1-555-01XX` / `+44-20-7946-0XXX`). Replace with real numbers when running. ### Input | Field | Type | Required | Description | |---|---|---|---| | `phoneNumbers` | string\[] | Yes | Phone numbers in any format (auto-normalized to E.164) | | `defaultCountryCode` | string | No | ISO 3166-1 alpha-2 code (US, GB, IN, etc.) for numbers without country code | | `whapiApiKey` | string | Yes | Your Whapi.Cloud API key | | `dryRun` | boolean | No | Normalize numbers only, skip WhatsApp check (default: false) | ### Output Each number produces one result object in the dataset: ```json { "phoneNumber": "+15550100", "normalized": "+15550100", "hasWhatsApp": true, "whatsAppId": "14155552671", "status": "success", "error": null } ``` | Field | Type | Description | |---|---|---| | `phoneNumber` | string | Original input number | | `normalized` | string | E.164 normalized format | | `hasWhatsApp` | boolean/null | `true` if active, `false` if not, `null` if unknown or dry run | | `whatsAppId` | string/null | WhatsApp ID if registered | | `status` | string | `success` or `error` | | `error` | string/null | Error message if status is `error` | ### Pricing **$0.003 per number checked.** Dry-run mode is free (normalization only). ### Phone Number Formats The actor handles various input formats: - International with `+`: `+15550100` - International with `00`: `004915512345678` - Local with default country: `9876543210` + `defaultCountryCode: "IN"` -> `+919876543210` - With spaces/dashes/parens: `(415) 555-2671` ### Rate Limiting Requests are rate-limited to 2 per second to stay within Whapi.Cloud API limits. ### Limitations - Requires an active Whapi.Cloud account with a connected WhatsApp number - Rate limited to 2 checks/second (batch of 1,000 numbers takes ~8 minutes) - Accuracy depends on WhatsApp's contact lookup (some numbers may show as unregistered if recently changed) - The connected WhatsApp number must not be banned or restricted ### Related Tools - [Broken Link Checker](https://apify.com/store) — Crawl websites and find broken links - [LinkedIn Profile Scraper](https://apify.com/store) — Extract public LinkedIn profile data - [Email Validator](https://apify.com/store) — Validate email addresses in bulk ## Tue Apr 14 22:51:14 IST 2026 # Actor input Schema ## `phoneNumbers` (type: `array`): List of phone numbers to validate. Can be in any format — they will be normalized to E.164 automatically. Include country code or set Default Country Code below. ## `defaultCountryCode` (type: `string`): ISO 3166-1 alpha-2 country code (e.g., US, GB, IN) used when phone numbers don't include a country code. Leave blank if all numbers already have country codes. ## `whapiApiKey` (type: `string`): Your Whapi.Cloud API key. Sign up at https://whapi.cloud to get one (free tier available). Required for all non-dry-run checks. Leave blank if using Dry Run mode. ## `dryRun` (type: `boolean`): If enabled, only normalizes phone numbers without calling the WhatsApp API. Useful for testing number formatting. No API key required in this mode. ## Actor input object example ```json { "phoneNumbers": [ "+15550100", "+15550101" ], "defaultCountryCode": "US", "dryRun": true } ``` # 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 ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "phoneNumbers": [ "+15550100", "+15550101" ], "defaultCountryCode": "US", "dryRun": true }; // Run the Actor and wait for it to finish const run = await client.actor("accurate_pouch/whatsapp-validator").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
