Overview
A Slack app is a conversation with its users. This exam tests the design, the APIs and the security.
Slack Developer is a Developer exam for people who build Slack apps; Salesforce recommends 6 months with its APIs and a prior app. It covers how apps fit the platform, then Bolt, Block Kit and the Slack APIs; interactive flow carries 20% and security 19%. It has no prerequisite, runs 60 questions in 90 minutes and covers Grid scale, admin APIs and Marketplace distribution.

What it tests
Learn all the way down.
Learn all the way down.
Perform when it matters.
Build on Bolt and the APIs
Use Bolt, the Web API and the Events API, pick HTTP or Socket Mode, and handle rate limits with retries.
Secure the app
Install with OAuth, request only the scopes you need, pick the right token and verify requests from Slack.
Scale and ship it
Design for Enterprise Grid, work with Slack Connect, automate administration through APIs, and distribute the app.
Course outline
A Slack app people reach for,
A Slack app people reach for,
built to be safe, fast and shipped.
We design this course ourselves. Salesforce runs the exam and issues the credential, and LUNARTECH is independent of Salesforce.
Start with where an app lives: workspaces, channels, users and the surfaces an app can use. You compare apps with workflows, learn how apps are managed after install, and choose the right surface before writing code.
- Workspaces, orgs and where apps live
- Apps compared with workflows
- Surfaces: messages, App Home, modals and canvases
- How admins install and manage apps
- Choosing a surface for a use case
You build A design note that picks the surfaces for a real app idea and says why.
Set up a working project the way a team would. You describe an app with a manifest, scaffold it with the Slack CLI, build on Bolt, and test in a developer sandbox instead of a live workspace.
- Describing an app in a manifest
- Scaffolding a project with the Slack CLI
- Bolt: listeners, middleware and context
- Developer sandboxes for safe testing
- Local development with tunnels and Socket Mode
- Logging and inspecting what Slack sends
You build A Bolt app running in a sandbox that answers a first command.
Users meet your app through entry points. You wire up slash commands, shortcuts, incoming webhooks and interactive components, acknowledge each request in time, and plan the path from first touch to finished task.
- Slash commands and their payloads
- Global and message shortcuts
- Incoming webhooks for one-way messages
- Acknowledging interactions in time
- Responding later with response URLs
- Mapping a user’s path through the app
You build An app with a command, a shortcut and a button that work as one flow.
Block Kit makes messages and views feel native to Slack. You assemble layouts from blocks and elements, build App Home and modals that update as people work, and follow patterns that keep an interface clear.
- Blocks, elements and composition objects
- Designing readable messages
- Building and updating App Home
- Modals, stacked views and validation
- Handling input from views
- Testing a layout before shipping it
You build An App Home and a modal form built from Block Kit, wired to real input.
Slack offers several ways in and out, and each suits a different job. You compare the Web API and Events API, choose between HTTP and Socket Mode, and handle rate limits so a busy workspace never breaks the app.
- Web API methods and pagination
- Events API subscriptions and delivery
- HTTP endpoints against Socket Mode
- Reading rate-limit responses and retrying
- Queuing work to stay under limits
- Picking the right API for a task
You build A service that listens for events and posts replies, with retry handling for rate limits.
A Slack app holds real access to people’s conversations, so its security is part of the design. You run the OAuth install flow, ask only for the scopes you need, pick the right token type, and prove every request came from Slack.
- The OAuth install flow, step by step
- Requesting the narrowest scopes
- Bot tokens against user tokens
- Verifying request signatures
- Storing and rotating secrets
- Reviewing an app for over-broad access
You build An installable app with scoped OAuth, request verification and secrets kept out of code.
Large customers run many workspaces under one org, and apps must work there. You learn how Grid is built, how its roles and org-level installs change an app, and how shared channels affect what your app can see.
- How Enterprise Grid is structured
- Org-level installs and workspace access
- Roles and what each can approve
- Apps inside Slack Connect channels
- Developer sandboxes for Grid testing
- Designing one app for many workspaces
You build An app design that works across a multi-workspace org and a shared channel.
Some apps manage Slack itself. You automate provisioning with SCIM, read activity through the Audit Logs API, work with admin and legal-hold APIs, and learn which token an org owner needs for each.
- Provisioning users and groups with SCIM
- Reading the Audit Logs API
- Admin APIs for apps, channels and members
- Legal holds and what they preserve
- Org-owner tokens and their reach
- Keeping administrative automation accountable
You build A script that provisions a user and reports recent audit events.
An app’s life continues after the first install. You test in staging, choose how to distribute it from one workspace to the Slack Marketplace, prepare for review, and plan updates that do not surprise installed customers.
- Staging and production apps
- Distribution models for an app
- What Marketplace review looks for
- Preparing listing, support and privacy material
- Releasing updates and new scopes
- Monitoring a live app
You build A release plan with a review-ready listing for one app.
Design and build one app that uses the platform well. You choose surfaces and APIs, secure the install, handle scale and limits, and finish with a distribution plan you can defend.
- Scoping an app and its audience
- Choosing surfaces and APIs
- Building, securing and testing it
- Preparing for Grid and for scale
- Presenting the release plan
You build A working Slack app with a security review and a distribution plan.
