# Java Messaging Quickstart

This quickstart serves as a guide to get your first Messaging application up and running with [FreeClimb](https://docs.freeclimb.com/docs/how-freeclimb-works).

Specifically, the project will:

- Receive an incoming message via a FreeClimb application
- Respond "Hello World!" to the incoming message

## Tutorial

We offer a [Java Messaging Quickstart Tutorial](https://docs.freeclimb.com/docs/java-messaging-quickstart) for more detailed set-up instructions and explanation of how FreeClimb works.

## Requirements
A [FreeClimb account](https://www.freeclimb.com/dashboard/signup/)

A [registered application](https://docs.freeclimb.com/docs/registering-and-configuring-an-application#register-an-app) with a named alias

A [configured FreeClimb number](https://docs.freeclimb.com/docs/getting-and-configuring-a-freeclimb-number) assigned to your application

Trial accounts: a [verified number](https://docs.freeclimb.com/docs/using-your-trial-account#verifying-outbound-numbers)

Tools:
- [Java](https://www.oracle.com/java/technologies/downloads/) 8 or higher
- [ngrok](https://ngrok.com/download) (recommended for hosting)
- [Gradle](https://gradle.org/install/)

## Setting up the Quickstart

1. Configure environment variables (in `.env.sample` and rename the file to `.env`):

| ENV VARIABLE | DESCRIPTION |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| ACCOUNT_ID | Account ID which can be found under [API credentials](https://www.freeclimb.com/dashboard/portal/account/authentication) in dashboard. |
| API_KEY | API key which can be found under [API credentials](https://www.freeclimb.com/dashboard/portal/account/authentication) in dashboard. |
| FREECLIMB_NUMBER | The number that sends messages from your application. Your FreeClimb number. |

2. Make your local server publicly accessible
```bash
ngrok http 3000
```
Once you run ngrok you should receive a response with a public URL, that looks something like 'https://ba1c-63-209-137-19.ngrok-free.app'.

3. [Configure your applications's endpoints](https://docs.freeclimb.com/docs/registering-and-configuring-an-application#configure-your-application) by adding a publicly accessible URL (we recommend an [ngrok](https://ngrok.com/download) URL) and the route reference `/incomingSms` to your App Config's SMS URL field:

```bash
https://YOUR-URL.ngrok.io/incomingSms
```

## Running the Quickstart
1. Start your voice quickstart application

```bash
gradle build && java -Dserver.port=3000 -jar build/libs/Java-Messaging-Quickstart-plain.jar
```

2. Call the FreeClimb number assigned to the application you've configured for this tutorial

## Using Docker to Run the Quickstart

1. Pull docker image from dockerhub

```bash
docker pull freeclimbapi/java-sms-quickstart
```

2. Run docker image after replacing placeholder values

```bash
docker run -e ACCOUNT_ID= -e API_KEY= -e FREECLIMB_NUMBER= -p 3000:3000 freeclimbapi/java-sms-quickstart
```
