Part 1: Getting Going with the Starter Kit Businesses depend on Slack for communication and Salesforce for data management. As one might expect, conversations in Slack don’t always correlate to changes in Salesforce records. Being able to share data between these two services can increase team productivity by eliminating the need to switch between them. In December of 2021, Salesforce produced using their APIs. Building on top of any platform can be intimidating: You have to learn about how authentication works, the methods you can call, the events you can listen for, and so on. Slack has and an SDK, , which reduces a lot of boilerplate logic, getting you more quickly from an idea to an actual app. a video series explaining how to build Slack Apps excellent documentation Bolt The folks at Salesforce have done one better. Taking into account Bolt’s development principles and tooling, they developed the . It’s an opinionated scaffolding framework designed to make it easy to build Slack Apps that integrate with Salesforce data. Slack Starter Kit In this series of posts, we’ll show you how to use the Slack Starter Kit and Bolt to create an application that allows users to view and change Salesforce records—entirely in Slack. By the end of this series, we’ll have a fully functional Slack app that communicates with the Salesforce platform. In this first post, we’ll go through the SDK and set up your development environment for future work! Prerequisites Before we begin, make sure you have the following software installed on your machine: —this is a tool designed by Salesforce to simplify platform interactions. The sfdx CLI A recent version of (>= 14.0) Node The , as well as an existing Heroku account Heroku CLI A Slack workspace where you can install Apps An existing Salesforce Dev Hub We’ll first create a Slack App, which will provide us with tokens and other Slack-specific information we’ll need before building our app. To do that: Navigate to and click . https://api.slack.com/apps Create New App In the prompt that pops up, select . From scratch Set the name of the App to , and choose a workspace where the App can be installed. SFDCContactEditor That’s it! If you scroll down, you’ll see your App Credentials. We’ll be referring to these in the next section. On the left side nav bar, click on App Manifest. Your App Manifest defines some metadata about your app, such as the permissions it requests and the events it handles. Paste the following YAML into that box, overwriting what was there by default: _metadata:

cd salesforce-slack-starter-kit/scripts Install the dependencies there with ; then pop up a folder, and install those dependencies: npm install npm install
cd ..
npm install Walking through the Salesforce Starter Kit With the Salesforce Starter Kit available and its dependencies installed, it’s time to take a look at what the Starter Kit can do. The primary goal of the Starter Kit is to get your environment set up for building, testing, and deploying a Slack App that integrates with Salesforce. It does this by: Setting up a Salesforce scratch org Setting up and deploying a sample application to Heroku Using Bolt to abstract away details with authentication Setting up a project structure that favors convention over configuration Let’s see this in action. First, make sure you’re authenticated to your Salesforce Dev Hub by running . Then, run , and a CLI prompt will take over. sfdx auth:web:login node scripts/deploy.js You’ll be asked to provide some information: For the Heroku App Name, we’ll use . Make sure to select a unique name for your Heroku App, since app names need to be unique across all Heroku apps. sfdc-contact-editor For the Slack Bot Token, go to the OAuth & Permissions page in your Slack App overview, and copy-paste the Bot User OAuth Token into the terminal. For the Slack Signing Secret, go back to the App Credentials section of the Basic Information page on Slack’s site. Copy-paste the provided signing secret into the terminal. Provide the name of your existing Dev Hub alias. You can name your scratch org anything you like—the default of is fine! scratchorg Now, grab a beverage and sit back, as the Starter Kit sets up some accounts for you. It creates a brand new scratch org and a new Heroku app, and it defines some essential environment variables for the deployed app to use. : if you receive a failure about a missing , make sure you have . If you receive a failure about a missing public key or permissions when pushing to Heroku, run . Note OrgCreateCommand enabled Dev Hub heroku keys:add After some time, you’ll receive the following message: Done deploying Heroku app sfdc-contact-editor In order to verify that the application was configured and deployed, you can perform two separate steps. First, run the following command in your terminal window: sfdx force:org:open Navigate to , and you should see an app titled “Connected App For Slack.” This is the Salesforce platform policy that the Starter Kit created for your Slack app. Manage Connected Apps Next, go to , and you should see your brand new app listed there. https://dashboard.heroku.com/ Now that we have a production version of the app available, we’ll need to make one more change to our Slack configuration to unite the two. Open up your and find the lines that identify your Heroku endpoint: App Manifest two request_url: https://heroku-app.herokuapp.com/slack/events Replace the placeholder with the actual name of your Heroku app. Click . Slack will inform you that your request URL isn’t verified; click to make that happen! heroku-app Save Changes Verify Watching it work Let’s try interacting with our app to ensure that everything is wired up correctly. Remember: we have a production app running on Heroku which intercepts a user’s Slack activity and communicates with Salesforce. We haven’t added any of our own functionality yet; everything was preconfigured by the Starter Kit. First, . You’ll be asked to authenticate with Salesforce; click on the button to do so. Then, head into any Slack room, and run the : add the app to your Slack workspace whoami shortcut provided by the app Voila! Next, let’s take a quick look at what’s inside the Starter Kit. Open up the project in your IDE, and navigate to the folder. In here, there’s a file called . This is where the entirety of the Salesforce authentication takes place. We don’t need to do anything to this file, but it’s useful to know just how much is being abstracted away for us. salesforcelib connect.js Next, open up the folder. This folder contains all the app logic for listening to and responding to events from Slack. Open up , then . This file contains all of the functionality for the shortcut we just issued. There are two important things to point out: listeners shortcuts whoami.js The first method called in the function is . Slack requires that an app acknowledge an event within three seconds of it occurring, and is responsible for sending that message to Slack. ack ack In the next line— —we fetch our connection information from Salesforce. const conn = context.sfconnection Lastly, let’s take a look at the user-interface folder. As you might have guessed, this folder contains all of the UI definitions for our Slack app. (We’ll definitely take a deeper look at how to build a UI in our next part.) Inside here, open up the modals folder, then open . The Starter Kit takes care of the actual definitions for designing and prompting the UI modal we saw. The only thing we can customize is the box text. Let’s get cheeky and add an exclamation point to the end of this sentence: whoami-response.js Successfully connected to salesforce instance ${instanceurl}. Authenticated with user ${username}! Let’s deploy this app live to production! If you don’t know how, you should familiarize yourself with . Put simply, however, all we need to do is push our committed change to our Heroku remote: this article on deploying to Heroku $ salesforce-slack-starter-kit (main): git add apps/slack-salesforce-starter-app/user-interface/modals/whoami-response.js
$ salesforce-slack-starter-kit (main): git commit -m "Add an exclamation point"

$ git push heroku main When Heroku is finished, you can return to Slack, issue the same shortcut, and see your new change live. whoami Learning more Whether you’re an experienced developer or just getting started, the Slack Starter Kit can save you so much time. In our short time together, we were able to: Create a new Salesforce environment Create a new Slack app Deploy the Slack app to Heroku Wire up Slack, Heroku, and Salesforce Issue a Slack shortcut and see the results The Starter Kit has essentially solved a lot of problems around authentication and API tokens by automating much of this for us. Every app will need these aspects configured, and since the Starter Kit has made these repetitive processes easier, we can now concentrate on what matters most: developing an incredible Slack app. With this foundation established, we’re ready to continue building on it in our next installment! We’ll look a little closer at the architecture of the Starter Kit, and add a new command of our own. Also Published . here
