FAQ
How to send messages to multiple phone numbers
You just have to send multiple API requests, one per target phone number.
For instance, if you want to send a message to 10 phone numbers, you should send 10 independent HTTPS requests to the API.
There is no option to send multiple messages in a single API request.
How to validate if a phone number can receive WhatsApp messages
You can validate if a given phone number is linked to a WhatsApp account and can receive messages.
The API provides an endpoint that can validate whether a given phone number exists in WhatsApp or not.
The only requirement is to have at least one WhatsApp number connected to the platform in your current account.
For more details, please check out the API endpoint documentation here.
Before you check if a phone number exists on WhatsApp, you can also validate and normalize the format of a list of phone numbers by using the numbers validator API endpoint. This endpoint only validates the correct E164 format, but it does not check whether the phone number effectively exists on WhatsApp.
Note: The number of WhatsApp check validations is limited per month based on your subscription plan. Please check out the pricing table for more details about the limits.
