FAQs
Is the number of API keys related to the account or the device? If I have two devices do I have two API keys?
Each account has 1 API key, so if you have two devices in the same account you would only have 1 API key.
If you need 2 API keys, you can create 2 different accounts with one device each. There are no additional costs.
What programming languages can I use for the API integration?
You can use any programming language to perform HTTPS requests to remote servers.
This also includes command-line tools like cURL, httpie, and graphical tools like Postman.
How can I validate if a phone number exists in WhatsApp?
You can validate whether a given phone number exists in WhatsApp or not, and therefore can receive messages in WhatsApp, by using the Number exists API endpoint.
Please note you must have at least one WhatsApp number connected to the platform to perform the validation.
Further useful resources
For more details about the endpoint API, please check our documentation. You will find all the details about the accepted request params, possible success or error responses and ready-to-use code examples in multiple programming languages.
