The WhatsApp Contact Validation 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 Validation 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 batch, 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 about the number's status, such as whether it is active on WhatsApp.
The response data is organized in a structured JSON format. Each response includes an array of results for the validated numbers, with each result containing fields for the phone number and its validation status.
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 requests by including multiple numbers in the bulk validation request.
Both endpoints provide information on the validity of WhatsApp numbers. The validation endpoints can also return additional details, such as the number's active status, which helps in segmenting and prioritizing contacts.
Data accuracy is maintained through regular updates and checks against WhatsApp's active user database. The API employs algorithms to ensure that only real, active numbers are validated, minimizing the risk of incorrect data.
Typical use cases include validating user-submitted WhatsApp numbers during registration, ensuring accurate contact lists for marketing campaigns, and automating customer support communications to enhance engagement.
If the validation returns partial or empty results, users should implement error handling to manage invalid numbers. This may include notifying users to check their input or logging invalid entries for further analysis.

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. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
