📱🔄 Zoom Slack Sync

Zoom Slack Sync is a serverless application built upon the serverless framework.

Get set up in a matter of no time! ⏰

All you need to do is:

1. Create a Slack app
2. Create a Zoom app
3. Clone this repo
4. Copy and fill out the .env file
5. Sign in to AWS on the CLI
6. Deploy with a single 👀 yarn deploy command
7. Users can (en/dis)able this integration by typing /statusupdater in your Slack workspace.

⚙️ Prerequisites

• An AWS account (We will be creating three Lambdas and a DynamoDB table)
• Zoom user account with Developer permissions
• Slack user account with the ability to create apps and add them to a workspace.

How it works

See it in action

The gif below outlines what this repo will allow you to achieve.

OAuth Flow

Once set up, a user in your Slack workspace can start syncing their Zoom and Slack status' by typing /statusupdater.
The user will then be asked to authorise the Slack app.

After authorisation the user will be informed the sync is now live.

The user can stop syncing their status' at any time by retyping the slash command /statusupdater.

👷 Installation

First of all you will need to

1. Install serverless

npm install -g serverless

yarn global add serverless

2. Give serverless access to AWS

🤖 1. Create a Slack App

Create a Slack App and add it to your Slack Workspace.

Basic Information

• Give you app a name like "Zoom Slack Sync" (this is how your App will appear in Slack).
• Set an app icon, I've included a free one in this repo under images for you to use.

OAuth & Permissions

First add your Bot/User Token Scopes.

• Bot Token Scopes: commands chat:write im:write
• User Token Scopes: users.profile:write.

Then go ahead and hit the Install App to Workspace button to add your App to Slack.
Redirect URL: After running yarn deploy in Step 3. Deploy you will see an endpoint output in the terminal that ends with /zoom-status-change-authorize-redirect (Paste this in here).

Slash Commands

Go ahead and Create a New Command like /statusupdater. (Again, we will need to add the Request URL in Step 4 after deployment so just set it to be https://google.com for now.)

🤖 2. Create a Zoom App

You will need to create a JWT Zoom app.

• Tab: Information - Fill this tab out with your details
• Tab: App Credentials - Generate a JWT
  • (Note: When your JWT expires you will need to redeploy in Step 3 with the new JWT)
  • Keep this to one side to put in your .env file later.
• Tab: Feature
  • Generate a Verification Token
    • Keep this to one side to put in your .env file later.
  • Add an Event Subscription
    • Name: This can be anything
    • Event type 1: Meeting - Participant/Host joined meeting
    • Event type 2: Meeting - Participant/Host left meeting.
    • Event type 3: Meeting - End meeting.
  • Event notification endpoint URL: Come back to this in Step 4 (put a dummy url for now)
• Tab: Activate - Don't activate yet. Come back to this in Step 4.

🚀 3. Deploy

Create a .env file in the root directory and add the following.
Environment variables prefixed with CUSTOM_ are optional and have defaults assigned.
I've outlined where you can find the values below.

CUSTOM_EMOJI=:zoom:                   <Default: :calling: - This can be any emoji code in your Slack Workspace (custom too)>
CUSTOM_STATUS="On a call"             <Default: On a Zoom>
CUSTOM_SLACK_SLASH_COMMAND=syncstatus <Default: statusupdater>

AWS_REGION_DEFAULT=                   <AWS - e.g. eu-west-1>

SLACK_APP_ID=                         <Slack App - Basic Information Tab>
SLACK_VERIFICATION_TOKEN=             <Slack App - Basic Information Tab>
SLACK_CLIENT_ID=                      <Slack App - Basic Information Tab>
SLACK_CLIENT_SECRET=                  <Slack App - Basic Information Tab>
SLACK_OAUTH_TOKEN=                    <Slack App - OAuth and Permissions - Bot User OAuth Access Token>

ZOOM_VERIFICATION_TOKEN=              <Zoom App - Feature Tab>

SLACK_REDIRECT_URI=                   <This will be output after running yarn deploy, see below..>

Deploy your serverless application

yarn deploy

Check your terminal output for an endpoint ending with /zoom-status-change-authorize-redirect.
Add this to your .env file as the following

SLACK_REDIRECT_URI=https://abcdef.execute-api.eu-west-1.amazonaws.com/dev/zoom-status-change-authorize-redirect

Deploy your serverless application for a final time.

yarn deploy

👷‍♀️ 4. Go back and add the final bits

When you ran yarn deploy in Step 3 a number of endpoints would have been output in the terminal - we will need to add them to your Slack and Zoom apps.

1. Slack App: Update your Redirect URL

   Go to the OAuth & Permissions tab and add the endpoint that ends with /zoom-status-change-authorize-redirect as a Redirect URL.

2. Slack App: Update your Slash Command Request URL

   Go to the Slash Commands tab and add the endpoint that ends with /slack as a Request URL.

3. Slack App: Turn on Interactivity

   Go to the Interactivity & Shortcuts tab and add the endpoint that ends with /slack as a Request URL.

4. Zoom App: Add your Notification Endpoint URL

   Go to the Feature tab and add the endpoint that ends with /zoom-status-change as the Notification Endpoint URL in your Event Subscriptions.

5. Zoom App: Activate

   Go to the Activation tab and hit the activate button.

Using the integration

Once you have followed steps 1-4 above you should be ready to go! Head over to the Slack workspace where you installed your Slack App.

• Type your slash command e.g. /statusupdater and this should initiate the OAuth workflow by setting a button to the user that will take them to your Slack App's authorisation page. Once they click the button they will be redirected back to your Slack App and a message will inform the user that their status' are now in sync.
• To stop syncing type your slash command again e.g. /statusupdater.

🚧 Debugging

Have you followed steps 1-4 and tried testing your integration and is something not working?

• Double check your Slack app and Zoom app are both configured correctly.
• Check out the Lambda Logs
  • Log in to the AWS Console and go to Lambda, you should see three lambdas called:
    • status-sync-dev-zoom-status-change-authorize-redirect
    • status-sync-dev-zoom-status-change
    • status-sync-dev-slack
• Check our your DynamoDB table
  • Log in to the AWS Console and go to DynamoDb, you should see a table called:
    • status-sync-data-table
  • When a user completes the OAuth flow they should appear in your DynamoDb table.
  • When a user turns off the integration they should be removed from your DynamoDb table.
