WhatsApp Detection

Check whether a mobile number is registered on WhatsApp using an API integration or the web-based verification tool. Choose the workflow that best fits your task: automate checks in your application, or verify a list of numbers without writing code.

Choose a verification method

API verification

Use the API when you want to check numbers from an application, script, or automated workflow. You can integrate with a command or a small amount of code, then use the returned registration status in your own process.

The API is designed for fast responses (about one second) and supports concurrent checks, making it suitable for real-time and higher-volume workflows.

Web-based bulk verification

Use the web interface when you want to verify numbers manually without writing code. You can check an individual number or provide a larger list in either of these ways:

• Upload a CSV or TXT file.
• Copy and paste multiple numbers into the interface.

Large batches are processed in the background. An email notification is sent when processing is complete, so you do not need to wait on the page.

How to get started

1. Choose API verification for an automated workflow, or web-based verification for manual and bulk checks.
2. Submit the mobile number or list of numbers using your chosen method.
3. Review the registration status results. For background batch processing, check your email for the completion notification.

About the results

WhatsApp Detection is a third-party verification service. It provides WhatsApp registration status data consistent with information available through official WhatsApp channels; it does not claim to connect directly to the official WhatsApp API.
