  • Deploy the code to heroku
  • Create a bot
  • Configure to your bot's credentials
• Make changes to the bot
  • Pull the code down to your local machine
  • Configure the local environment variables to your bot's credentials

Requirements:

• GroupMe account
• Heroku account
• Heroku Toolbelt

Get your bot up and running

Deploy to Heroku:

Be sure to log into heroku, using your heroku credentials, then click the link below.

You should be taken to a page that looks like this:

Optionally, you can give your app a name, or instead leave it blank and let Heroku name it for you (you can change it later).

Next, create a GroupMe Bot:

Go to: https://dev.groupme.com/session/new

Use your GroupMe credentials to log into the developer site.

Once you have successfully logged in, go to https://dev.groupme.com/bots/new

Fill out the form to create your new bot:

• Select the group where you want the bot to live
• Give your bot a name
• Paste in the url to your newly deply heroku app
  • http://your-app-name-here.herokuapp.com/
• (Optional) Give your bot an avatar by providing a url to an image
• Click submit

Find your Bot ID:

Go here to view all of your bots: https://dev.groupme.com/bots

Click on the one you just created.

On your Bot's page, copy the Bot Token (aka your Bot ID)

Add your Bot ID to your Heroku app:

Go here to see all of your Heroku apps and select the one you just created before:

https://dashboard-next.heroku.com/apps

On your app page, click settings in the top navigation:

On your app's setting page, find the Config Vars section and click the Reveal Config Vars button:

Then click edit:

Fill out the form to add an environment variable to your app:

• In the "key" field type: BOT_ID
• In the "value" field paste your Bot ID that you copied in the previous steps
• Click the save button

Now go test your bot!

Go to GroupMe and type "/cool guy" in the group where your bot lives to see it in action.

Make it your own

Pull the code to your local machine

Within terminal, change directory to the location where you would like the files to live, then run this command:

$ heroku git:clone -a YOUR_APP_NAME_HERE

And then change directory into the new folder

$ cd YOUR_APP_NAME_HERE

Configure your local BOT_ID environment variable

Open the file .env from your local files in your text editor of choice. Find where it says "YOUR_BOT_ID_HERE" and replace it with the ID of your new bot.

If you don't know what your Bot ID is, please refer back to this section, where it is explained how to retrieve it.

If your Bot ID is 12345678910, then:

BOT_ID="YOUR_BOT_ID_HERE"

becomes:

BOT_ID="12345678910"

Start the server

To test your bot locally, open terminal and run the following command to start a local server.

$ foreman start

Then navigate to http://127.0.0.1:5000/ in a browser.

All done! Go play around and make the bot your own.
