In every request, the endpoints of this API perform a series of meticulous validations to ensure the accuracy and security of the information being scraped. Firstly, it checks if the provided number is registered on WhatsApp. If the number is not registered, the API proceeds to validate if the number adheres to the proper mobile format. Once confirmed as a valid mobile number, the API then examines the user’s WhatsApp privacy settings to determine if access to the requested information is permitted. These comprehensive validations guarantee a seamless and secure experience, safeguarding both data integrity and user privacy.
