A blog that accompanies our progress creating this product

The following API can be used in c++ as shown in my article.

Here is how its done:

You need to define several constants:

//
#define    GroupAdmin                <YOUR GROUP ADMIN MOBILE PHONE>
#define GroupName                <YOUR GROUP NAME>
#define CLIENT_ID                <YOUR CLIENT ID>
#define CLIENT_SECRET            <YOUR CLIENT SECRET>

#define GROUP_API_SERVER        L"api.whatsmate.net"
#define GROUP_API_PATH          L"/v3/whatsapp/group/text/message/12"
#define IMAGE_SINGLE_API_URL    L"http://api.whatsmate.net/v3/whatsapp/group/image/message/12"

//

Then you connect to the API’s endpoint.

hOpenHandle = InternetOpen(_T("HTTP"), INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);
if (hOpenHandle == NULL)
{
    return false;
}

hConnectHandle = InternetConnect(hOpenHandle,
    GROUP_API_SERVER,
    INTERNET_DEFAULT_HTTP_PORT,
    NULL, NULL, INTERNET_SERVICE_HTTP,
    0, 1);

if (hConnectHandle == NULL)
{
    InternetCloseHandle(hOpenHandle);
    return false;
}

Then send both header and body and wait for the result that needs to be “OK”.

Step 1 – open an HTTP request:

const wchar_t *AcceptTypes[] = { _T("application/json"),NULL };
HINTERNET hRequest = HttpOpenRequest(hConnectHandle, _T("POST"), GROUP_API_PATH, NULL, NULL, AcceptTypes, 0, 0);

if (hRequest == NULL)
{
    InternetCloseHandle(hConnectHandle);
    InternetCloseHandle(hOpenHandle);
    return false;
}

Step 2 – send the header:

std::wstring HeaderData;

HeaderData += _T("X-WM-CLIENT-ID: ");
HeaderData += _T(CLIENT_ID);
HeaderData += _T("\r\nX-WM-CLIENT-SECRET: ");
HeaderData += _T(CLIENT_SECRET);
HeaderData += _T("\r\n");
HttpAddRequestHeaders(hRequest, HeaderData.c_str(), HeaderData.size(), NULL);

Step 3 – send the message:

std::wstring WJsonData;
WJsonData += _T("{");
WJsonData += _T("\"group_admin\":\"");
WJsonData += groupAdmin;
WJsonData += _T("\",");
WJsonData += _T("\"group_name\":\"");
WJsonData += groupName;
WJsonData += _T("\",");
WJsonData += _T("\"message\":\"");
WJsonData += message;
WJsonData += _T("\"");
WJsonData += _T("}");

const std::string JsonData(WJsonData.begin(), WJsonData.end());

bResults = HttpSendRequest(hRequest, NULL, 0, (LPVOID)(JsonData.c_str()), JsonData.size());

Now just check the result:

TCHAR StatusText[BUFFER_LENGTH] = { 0 };
DWORD StatusTextLen = BUFFER_LENGTH;
HttpQueryInfo(hRequest, HTTP_QUERY_STATUS_TEXT, &StatusText, &StatusTextLen, NULL);
bResults = (StatusTextLen && wcscmp(StatusText, L"OK")==FALSE);

Compile your code using Microsoft Visual Studio c++.
