# API integration with VB6

### Authentication

The first step is to register on the [Whapi.Cloud website](https://panel.whapi.cloud/register) and create an account. It's free and doesn't require you to enter a credit card.

After registration you will immediately have access to a test channel with a small limitation. Wait for it to start (it usually takes about a minute). You will need to connect your phone for Whatsapp automation. It is from the connected phone that messages will be sent. 

The big advantage of the service is that it takes only a couple of minutes to launch and start working.

Open your WhatsApp mobile app, navigate to **Settings** -> **Linked devices** -> **Link a device** -> **Scan QR code**

Our service enables you to interact with the API without the need for an uninterrupted phone connection. Operate WhatsApp on up to four paired devices and one mobile device concurrently.

Now save the generated API-Key token on channel page:

### How to Send WhatsApp API Message using VB6 <a href="#example-usage-for-whatsapp-api-using-php" id="example-usage-for-whatsapp-api-using-php"></a>

```vbnet
Private Sub SendMessage()
    Dim xml As Object
    Dim strNumber As String, strMessage As String
    Set xml = CreateObject("MSXML2.ServerXMLHTTP.6.0")
   
    Dim url As String
    url = "https://gate.whapi.cloud/messages/text"
   
    Dim apiKey As String
   
    apiKey = "Your API Key Goes Here"
    strNumber = "Recipient Number"  'Number should be in format countrycode+mobilenumber without + sign
   
    strMessage = "This is My First Message"
   
    Dim jsonBody As String
   
    jsonBody = "{""to"":""" & strNumber & """,""body"":""" & strMessage & """}"
   
    With xml
        .Open "POST", url, False
        .setRequestHeader "Authorization", "Bearer " & apiKey
        .setRequestHeader "Content-Type", "application/json"
        .send jsonBody
    End With
   
   
    If xml.Status = 200 Then
        MsgBox "Message sent successfully: " & xml.responseText
    Else
        MsgBox "Error: " & xml.Status & " - " & xml.statusText & vbCrLf & xml.responseText
    End If
