Tech stack

• AWS Lambda for the webhooks
• AWS DynamoDB to store Oauth 2.0 tokens
• Serverless framework to build and deploy

Deployment

1. Setup Serverless with AWS: https://github.com/serverless/serverless#quick-start
2. Create a new Slack app https://api.slack.com/apps and get your CLIENT_ID and CLIENT_SECRET
3. Create a secret.dev.yml file to store the values:

CLIENT_ID: 'YOUR_CLIENT_ID'
CLIENT_SECRET: 'YOUR_CLIENT_SECRET'

We use https://github.com/serverless/serverless-secrets-plugin to encrypt the secrets for our Bot

4. Deploy the hooks serverless deploy
5. In the Slack dashboard, setup

• The Incoming Webhook service to allow the bot to post messages
• The Event Subscription service with the message.channels bot permissions using your webhook Lambda as the Request URL
• The Oauth 2.0 service using your redirectUrl Lambda as the Redirect URL
