Samples

These sample applications demonstrate how to use the Ratatosk framework with each supported channel provider. Each sample is a standalone project with its own solution file and README.

Available samples

Sample	Channel	Type	Description
Facebook Messenger	Facebook Messenger	Console	Send/receive messages via Facebook Page
Telegram Bot	Telegram Bot	Console	Send messages via Telegram Bot API
SendGrid Email	SendGrid	Console	Send transactional emails
Firebase Push	Firebase FCM	Console	Send push notifications
Twilio SMS & WhatsApp	Twilio	Console	Send SMS and WhatsApp messages
Multi-Connector	All channels	ASP.NET Core API	REST API exposing all connectors
Sender Manager	SendGrid	ASP.NET Core API	CRUD sender identities + message send with polymorphic sender resolution

Prerequisites

• .NET 8.0 SDK

• Credentials for the messaging service(s) you want to test (see each sample's README)

How the samples work

The sample projects reference the framework source projects directly via <ProjectReference> in their .csproj files. This means:

• The framework is built automatically when you build or run a sample

• Changes to framework source code are immediately reflected in the sample

• No pre-built DLLs or manual build steps are required

Each sample has its own solution (.sln) file that includes both the sample project and the framework projects it depends on.

Running a sample

Each sample includes a run.sh convenience script:

cd samples/<name>
./run.sh -- <connector> <command>

Use the -v flag to enable verbose logging:

./run.sh -v -- <connector> <command>

To build without running:

dotnet build

To open in an IDE, open the sample's .sln file (e.g., samples/facebook-messenger/Facebook.sln).

Per-sample setup

Before running a sample, you need credentials for the messaging service. Each sample's README includes:

• Provider-specific setup instructions

• Configuration wizard (./run.sh -- <name> configure)

• Available commands (send, validate, receive, status, etc.)

• Environment variable reference
