How to Deploy a WhatsApp Bot to Production on Code Capsules

Deploy a WhatsApp Bot and learn how to host backend code on Code Capsules.

Set up

Code Capsules connects to GitHub repositories to deploy applications. To follow this guide, you’ll need a Code Capsules account, a GitHub account and a Twilio account.

To demonstrate how to deploy a WhatsApp Bot with Code Capsules, we’ve provided an example bot which you can find on the Code Capsules GitHub repository.

Sign in to GitHub, and fork the example bot repository by clicking "Fork" at the top-right of your screen and selecting your GitHub account as the destination.

Create a Space for your Bot

Log in to your Code Capsules account and navigate to the "Spaces" tab. Once there, click the yellow + icon on the top right of the screen to add a new Space.

Follow the prompts, choosing your region and giving your Space a name, then click "Create Space".

Example instructions to go with numbered annotations 1. Choose a team — you can use a default “personal” team if you’re the only person working on this project, or a named team if you’re collaborating with others 2. This should remind you of the project, for example “customer-api” or “notetaking-app” 3. Choose a country close to where most of your users will be 4. If you’re already using a specific cloud, you can choose that here, otherwise pick any one.

Create the Capsule

A Capsule provides the server for hosting an application on Code Capsules.

To create a new Capsule for your space follow the instructions below:

  1. Choose "Backend Capsule", your Team and Space.
  2. Choose your payment plan.
  3. Click the GitHub button and give access to the repository you forked at the start of the tutorial.
  4. Choose the GitHub repository you forked.
  5. Press "Next".
  6. Leave "Run Command" blank.
  7. Click "Create Capsule".

Code Capsules will automatically build your application when you’ve finished creating the Capsule.

Once your application is live, you can view the build log by selecting the "Deploy" tab and clicking the "View build log" link in the "Builds" section.

Create a Twilio Sandbox

The Twilio Sandbox provides a development environment to access the WhatsApp API. Sign up for a Twilio account to use a sandbox that allows you to test your bot in realtime. After you've logged into your Twilio account, navigate to the console page to configure your WhatsApp sandbox settings.

  1. Go to your capsule's "Details" tab and copy your bot's domain under the "URL" section. Capsule Domain
  2. Head back to your Twilio console and paste the domain in the "When a Message Comes In" field and append /bot to the end of it. Make sure the method is set to HTTP Post. Sandbox Config
  3. Scroll down to the bottom of the page and click "Save".
  4. Under the "Sandbox Participants" section you will find the WhatsApp number for your sandbox and a code to join it that starts with join. Send this code to the displayed WhatsApp number to add your personal number as a sandbox participant. Sandbox Participants

Chat with the Bot

The bot will now be able to respond to your messages after sending the join code. Try it and the bot should echo any message you send it.
