{% anchor h2 %} Parse Webhook {% endanchor %}

In this example, we want to parse all emails at address@email.sendgrid.biz and post the parsed email to http://sendgrid.biz/upload

Given this scenario, the following are the parameters you would set at the Parse API settings page:

{% codeblock %} Hostname: email.sendgrid.biz {% endcodeblock %}

{% codeblock %} URL: http://sendgrid.biz/upload {% endcodeblock %}

Put this C# model in your models folder:

{% codeblock lang:csharp %} ///

/// A model with the data format of the Inbound Parse API's POST /// public class Email { /// /// The Domain Keys Identified Email code for the email /// public string Dkim { get; set; }

///

/// The email address that the email was sent to /// public string To { get; set; }

///

/// The HTML body of the email /// public string Html { get; set; }

///

/// The email address the email was sent from /// public string From { get; set; }

///

/// The Text body of the email /// public string Text { get; set; }

///

/// The Ip address of the sender of the email /// public string SenderIp { get; set; }

///

/// A JSON string containing the SMTP envelope. This will have two variables: to, which is an array of recipients, and from, which is the return path for the message. /// public string Envelope { get; set; }

///

/// Number of attachments included in email /// public int Attachments { get; set; }

///

/// The subject of the email /// public string Subject { get; set; }

///

/// A JSON string containing the character sets of the fields extracted from the message. /// public string Charsets { get; set; }

///

/// The results of the Sender Policy Framework verification of the message sender and receiving IP address. /// public string Spf { get; set; } } {% endcodeblock %}

To test this, we send an email to [email protected], and put the following method in our ApiController. Note: Don't forget the attribute.

{% codeblock lang:csharp %} // POST api/inbound [HttpPost] public async Task Post() { var root = HttpContext.Current.Server.MapPath("~/App_Data"); var provider = new MultipartFormDataStreamProvider(root); await Request.Content.ReadAsMultipartAsync(provider);

var email = new Email
{
	Dkim = provider.FormData.GetValues("dkim").FirstOrDefault(),
	To = provider.FormData.GetValues("to").FirstOrDefault(),
	Html = provider.FormData.GetValues("html").FirstOrDefault(),
	From = provider.FormData.GetValues("from").FirstOrDefault(),
	Text = provider.FormData.GetValues("text").FirstOrDefault(),
	SenderIp = provider.FormData.GetValues("sender_ip").FirstOrDefault(),
	Envelope = provider.FormData.GetValues("envelope").FirstOrDefault(),
	Attachments = int.Parse(provider.FormData.GetValues("attachments").FirstOrDefault()),
	Subject = provider.FormData.GetValues("subject").FirstOrDefault(),
	Charsets = provider.FormData.GetValues("charsets").FirstOrDefault(),
	Spf = provider.FormData.GetValues("spf").FirstOrDefault()
};

// The email is now stored in the email variable

return new HttpResponseMessage(HttpStatusCode.OK);

} {% endcodeblock %}

The above code used the following using's

{% codeblock lang:csharp %} using System.Linq; using System.Net; using System.Net.Http; using System.Threading.Tasks; using System.Web; using System.Web.Http; {% endcodeblock %}
