Getting Started

Install-Package Mandrill.net

Send a new transactional message through Mandrill (async)

var api = new MandrillApi("YOUR_API_KEY_GOES_HERE");
var message = new MandrillMessage("[email protected]", "[email protected]",
                "hello mandrill!", "...how are you?");
var result = await api.Messages.SendAsync(message);

Send a new transactional message through Mandrill (non-async)

All the api's are available in async or non-async in the .net 4.5 target version of this library. In .NET Core, only async is supported because the underlying api's for web requests in .NET are async only.

var api = new MandrillApi("YOUR_API_KEY_GOES_HERE");
var message = new MandrillMessage("[email protected]", "[email protected]",
                "hello mandrill!", "...how are you?");
var result = api.Messages.Send(message);

Send a new transactional message through Mandrill using a template

var api = new MandrillApi("YOUR_API_KEY_GOES_HERE");
var message = new MandrillMessage();
message.FromEmail = "[email protected]";
message.AddTo("[email protected]");
message.ReplyTo = "[email protected]";
//supports merge var content as string
message.AddGlobalMergeVars("invoice_date", DateTime.Now.ToShortDateString());
//or as objects (handlebar templates only)
message.AddRcptMergeVars("[email protected]", "invoice_details", new[]
{
    new Dictionary<string, object>
    {
        {"sku", "apples"},
        {"qty", 4},
        {"price", "0.40"}
    },
    new Dictionary<string, object>
    {
        {"sku", "oranges"},
        {"qty", 6},
        {"price", "0.30"}

    }
});

var result = await api.Messages.SendTemplateAsync(message, "customer-invoice");

Processing a web hook batch

[HttpPost]
public IHttpActionResult MyWebApiControllerMethod(FormDataCollection value)
{
    //optional: validate your webhook signature
    // see https://mandrill.zendesk.com/hc/en-us/articles/205583257-How-to-Authenticate-Webhook-Requests
    if(!ValidateRequest(value))
    {
      return Forbidden();
    }
    
    var events = MandrillMessageEvent.ParseMandrillEvents(value.Get("mandrill_events"));
    foreach (var messageEvent in events)
    {
        // do something with the event
    }
    return Ok();
}

private bool ValidateRequest(FormDataCollection value)
{
   IEnumerable<string> headers;
   if (!Request.Headers.TryGetValues("X-Mandrill-Signature", out headers))
   {
     return false;
   }
   var signature = headers.Single();
   var key = "MANDRILL_WEBHOOK_KEY_HERE";
   
   return WebHookSignatureHelper.VerifyWebHookSignature(signature, key, Request.RequestUri, value.ReadAsNameValueCollection());
}
