## Overview
Node-RED is an open-source flow-based programming tool that provides a visual development environment for building applications by wiring together nodes. It was originally developed by IBM Emerging Technology Services and is now part of the JS Foundation.
Node-RED allows users to create applications and services by connecting pre-built nodes together in a flowchart-like manner. Each node represents a specific task or function, such as reading data from a sensor, processing data, making decisions, or interacting with external systems. Users can drag and drop nodes onto a canvas, connect them together, and configure their properties.
The flows created in Node-RED are executed by a runtime engine, which runs on a server or device where Node-RED is installed. The runtime executes the flow in a sequential manner, passing data between nodes as it progresses through the flow. The flows can be easily modified and deployed, making it a flexible tool for building and prototyping Internet of Things (IoT) applications, automation workflows, and data integration processes.
## Start the journey
**node-red-telnyx** is the Telnyx powerful integration that allows you to combine the capabilities of Node-RED, a flow-based programming tool, with Telnyx, a cloud-based communications platform. With **node-red-telnyx**, you can create complex workflows and automate various telecommunications tasks.
**node-red-telnyx** can be integrated with other services and platforms through Node-RED's extensive library of nodes. You can connect Telnyx's communications capabilities with databases, APIs, messaging platforms, and IoT devices to build end-to-end automation solutions.
e.g., you can use **node-red-telnyx** to send SMS messages programmatically. This can be useful for notifications, alerts, or two-factor authentication (2FA) purposes. You can configure the flow to trigger SMS messages based on specific events or conditions.
To get started, [sign up](https://telnyx.com/sign-up) for a Portal account, then follow the steps in our quickstart guide to buy an SMS-enabled number.
## Usage
The package needs to be configured with your MCP account's API key and some other details you can find in the Telnyx [Mission Control Portal](https://portal.telnyx.com).
Both ways of sending SMS are supported.
* **Alphanumeric**: Alphanumeric Sender ID allows you to set your company name or brand as the Sender ID when sending one-way SMS messages to international destinations. Find more information [here](https://support.telnyx.com/en/articles/4371498-sending-alphanumeric-sms-sender-id).
* **Two-way**: You'll need an SMS-capable phone number purchased from, or ported into, the Telnyx platform. If purchasing a new number, select the SMS number feature when searching. In general, numbers that are ported in will be messaging-capable. [Learn more](https://developers.telnyx.com/docs/messaging/messages/send-message).
