The WhatsApp Contact Check API allows you to quickly, reliably, and automatically verify and validate WhatsApp numbers. Its main purpose is to help companies, developers, and platforms ensure that the numbers entered by users or customers are real, active, and use the messaging app, avoiding incorrect or inactive data that could affect communication.
The API is easy to integrate thanks to its flexible design and clear documentation, allowing users to easily incorporate it into web applications, mobile platforms, or CRM systems. It also helps automate mass verification processes, facilitating contact management in marketing campaigns, transactional notifications, and customer support.
In addition to basic validation, the service can return additional information about the status of the number, helping companies to better segment and prioritize their contacts. By filtering out invalid numbers before they enter mailing lists, resources are optimized and the effectiveness of communication via WhatsApp is increased.
The WhatsApp Contact Check API is designed to handle high volumes of queries with high response speeds, ensuring a smooth and scalable experience. Its focus on accuracy, efficiency, and simplicity makes it an essential tool for any organization seeking to improve the quality of its contact data and ensure the successful delivery of its messages.

The POST Validation endpoint returns a status indicating whether a WhatsApp number is 'valid' or 'invalid'. The POST Bulk Validation endpoint provides a similar status for each number in the submitted list, allowing for efficient validation of multiple contacts simultaneously.
The key fields in the response data include the phone number, validation status ('valid' or 'invalid'), and any additional information regarding the number's status, such as whether it is currently active on WhatsApp.
The response data is structured in a JSON format, with each entry containing the phone number and its corresponding validation status. For bulk requests, the response includes an array of results, each associated with the respective input number.
The POST Validation endpoint accepts a single phone number as a parameter, while the POST Bulk Validation endpoint accepts an array of phone numbers. Users can customize their requests by providing different numbers to validate in bulk.
Each endpoint provides information on the validity of WhatsApp numbers. The validation status indicates whether the number is active on WhatsApp, helping users filter out invalid contacts for better communication.
Data accuracy is maintained through continuous updates and validation checks against WhatsApp's active user database. The API employs quality control measures to ensure that the validation results reflect the current status of the numbers.
Typical use cases include validating customer contact information for marketing campaigns, ensuring transactional notifications reach the intended recipients, and improving customer support by confirming active WhatsApp numbers.
If the response contains partial or empty results, users should review the input numbers for formatting errors or invalid entries. Implementing error handling in the application can help manage these scenarios effectively.
To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs.

But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
