# WhatsApp Text Message

> Text messaging using Meta's WhatsApp

Sends a text message from and to a specific phone number using Meta's WhatsApp.

## Input

<ResponseField name="Phone Number WhatsApp ID" type="string" required>
  WhatsApp Id of the number that will send the message. In practice, you will usually want to have this as your WhatsApp Business Account Phone Number's WhatsApp Id.

  In case of a [Message Received](/guide/workflows/nodes/triggers/message-received-node) trigger node, you can use `Use fallback` to set this as the phone number that received the message in the trigger node.

  The `Use fallback` option is equivalent to interpolating `{{$nodes['Message Received'].message.to}}`.
</ResponseField>

<ResponseField name="Recipient WhatsApp ID" type="string">
  WhatsApp Id of the phone number that will receive the message.

  In most use cases of a [Message Received](/guide/workflows/nodes/triggers/message-received-node) trigger node, you will want to set this as the user's WhatsApp Id, that is who sent the message to the trigger node.

  To achieve this result, you can leave this field **blank** or use interpolation mode with `{{$nodes['Message Received'].message.from}}`.
</ResponseField>

<ResponseField name="Message Content" type="string" required>
  Content of the message to be sent.
</ResponseField>
