Need checks in your workflow?
The authenticated API checks one number per request. Use a compatible connected session, respect your quota and follow the documentation.
Before you use it
Can I check a number on this page?
This page explains the feature. It does not run public number checks. Create an account, connect a compatible WhatsApp number and follow the tutorial.
What do I need for a check?
A Wassenger account, a compatible WhatsApp session online and synced, and available verification quota. Supported checks and limits depend on your connection and plan.
Does a valid format mean the number is on WhatsApp?
No. Format validation and WhatsApp existence checks are different operations. Read the API documentation for the check you need.
