Authentication

If you don't have an authentication token, click here to generate one.

Production
Client client = new Client(@"your-api-token", false);

Sandbox
Client client = new Client(@"your-api-token", true);

Sending Messages

The first step to be able to send messages is to specify the ID number of origin:

client.numberId = "chave";

Then send the message and wait for a response.

If you want to send a message using data on your own, you can use:

@Message message = client.sendData(Object);

To check all the data that can be sent in each type of message, check the WhatsApp Business documentation.

If you prefer, we provide ready methods for each type of message.

@Message message = client.sendMessage(new Text()
    {
        text = new TextDetail() { body = "Olá Mundo" }

        to = "+999999999"
