Transmitly.ChannelProvider.SendGrid

Transmitly.ChannelProvider.SendGrid is the convenience package for sending email with Transmitly through Twilio SendGrid.

This is the package most applications should install. It wires together:

• Transmitly.ChannelProvider.SendGrid.Configuration
• Transmitly.ChannelProvider.SendGrid.Sdk

Supported channels:

• Email

Install

dotnet add package Transmitly.ChannelProvider.SendGrid

Quick Start

using Transmitly;

ICommunicationsClient client = new CommunicationsClientBuilder()
	.AddSendGridSupport(options =>
	{
		options.ApiKey = "your-sendgrid-api-key";
	})
	.AddPipeline("welcome-email", pipeline =>
	{
		pipeline.AddEmail("welcome@example.com".AsIdentityAddress("Example App"), email =>
		{
			email.Subject.AddStringTemplate("Welcome to Example App");
			email.HtmlBody.AddStringTemplate("<strong>Welcome</strong> to Example App.");
			email.TextBody.AddStringTemplate("Welcome to Example App.");
		});
	})
	.BuildClient();

var result = await client.DispatchAsync(
	"welcome-email",
	"customer@example.com".AsIdentityAddress("Customer"),
	new { });

Configuration

AddSendGridSupport(options => ...) accepts SendGridOptions.

Common settings:

• ApiKey: your Twilio SendGrid API key.
• Host: defaults to https://api.sendgrid.com.
• Version: defaults to v3.
• HttpErrorAsException: forward HTTP failures as exceptions from the underlying client.
• RequestHeaders, UrlPath, Auth, and ReliabilitySettings for advanced client configuration.

SendGrid-Specific Email Features

This package registers SendGrid email extensions through email.SendGrid().

The primary provider-specific setting is TemplateId, which lets you send with a SendGrid dynamic template instead of the channel subject/body content.

using Transmitly;

pipeline.AddEmail("welcome@example.com".AsIdentityAddress("Example App"), email =>
{
	email.Subject.AddStringTemplate("Welcome to Example App");
	email.TextBody.AddStringTemplate("Welcome to Example App.");
	email.SendGrid().TemplateId = "d-0123456789abcdef0123456789abcdef";
});

Delivery Reports

This package registers a SendGrid webhook adaptor that converts SendGrid event webhook payloads into Transmitly DeliveryReport instances.

Because SendGrid uses a static webhook URL per account, the Transmitly request adaptor expects the callback URL to identify the channel and provider. A common pattern is to use a URL such as:

https://your-app.example.com/communications/channel/provider/update?tlyc=Email&tlycp=SendGrid

If you are using the MVC integration packages, point the webhook at your Transmitly delivery-report endpoint and include the same query-string context.
