How to Run Claude Code from Slack for Growth Marketing: A Marketer's Step-by-Step Setup Guide

If you're a growth marketer watching everyone else level up with Claude's coding capabilities while feeling left behind, here's the good news: you don't need to become a developer. You can run Claude Code directly from Slack—the tool you already use every day.

This guide walks you through exactly how to set up and use Claude Code through Slack, even if you've never written a line of code. Let's turn that FOMO into momentum.

TL;DR

• Claude Code in Slack is a native integration—no middleware, no API keys, no Zapier needed. Just @mention Claude in a Slack channel with a coding task

• Claude automatically detects coding intent and creates a Claude Code session on the web, posting progress updates back to Slack

• Setup takes minutes: install the Claude app, connect your Claude account, link GitHub, choose a routing mode, and invite Claude to channels

• Two routing modes: "Code only" (all requests go to Claude Code) or "Code + Chat" (Claude intelligently routes between coding and chat tasks)

• Growth marketers use it for: generating marketing scripts, building custom dashboards, automating data pipelines, analyzing campaign data, and creating PR-ready code—all initiated from Slack

• Security is built in: sessions run under your own Claude account, repositories use your GitHub permissions, and enterprise controls are available

• Start this week: get a Pro/Max/Team plan, connect GitHub, invite Claude to your marketing channel, and @mention it with your first task

Why Growth Marketers Need Claude Code Access

Claude Code isn't just another AI chatbot. It's a full coding agent that can write, execute, and iterate on code—handling tasks that would normally require developer resources.

Marketing teams using AI coding tools report 30-40% time savings on routine technical tasks. The catch: most marketers feel intimidated by the setup. Claude Code in Slack removes that barrier entirely. You @mention Claude, describe what you need in plain English, and it builds it.

What makes Claude Code valuable for growth marketing:

• Data analysis: Process spreadsheets, analyze campaign performance, and surface trends—no SQL required

• Script generation: Create custom Google Sheets formulas, tracking scripts, and API integrations

• Automation building: Build marketing automations using natural language instructions

• Parallel execution: Kick off coding tasks in Slack while you continue other work. Claude notifies you when it's done

The real breakthrough? This all happens inside Slack, where your team already collaborates.

Understanding Claude Code in Slack: What Actually Happens

When you @mention Claude in a Slack channel with a coding task, here's the flow:

1. Initiation — You @mention Claude with a coding request

2. Detection — Claude analyzes your message and detects coding intent

3. Session creation — A Claude Code session is created on claude.ai/code

4. Progress updates — Claude posts status updates to your Slack thread as work progresses

5. Completion — Claude @mentions you with a summary and action buttons

6. Review — Click "View Session" to see the full transcript, or "Create PR" to open a pull request

This is not a DIY API integration. It's a native feature built into the Claude for Slack app. Claude intelligently routes between regular chat and full coding sessions based on what you ask.

Prerequisites: What You Need Before Starting

The barrier to entry is low. Here's the checklist:

Essential Requirements

Optional But Helpful

• A GitHub repository with your marketing scripts, templates, or data pipelines

• Your marketing data in accessible formats (Google Sheets, CSV files, or connected CRM)

• A dedicated Slack channel for Claude coding requests (e.g., #marketing-claude-code)

Step-by-Step: Setting Up Claude Code in Slack

Step 1: Install the Claude App in Slack

A workspace administrator must install the Claude app from the Slack App Marketplace.

1. Visit the Slack App Marketplace and search for "Claude"

2. Click "Add to Slack" to begin installation

3. Approve the requested permissions for your workspace

If you're not a workspace admin, ask your IT team or Slack admin to install it.

Step 2: Connect Your Claude Account

After the app is installed, link your individual Claude account:

1. Open the Claude app in Slack by clicking on "Claude" in your Apps section

2. Navigate to the App Home tab

3. Click "Connect" to link your Slack account with your Claude account

4. Complete the authentication flow in your browser

Each user runs sessions under their own Claude account. Usage counts against your individual plan limits.

Step 3: Configure Claude Code on the Web

Make sure your Claude Code web environment is ready:

1. Visit claude.ai/code and sign in with the same account you connected to Slack

2. Connect your GitHub account if not already connected

3. Authenticate at least one repository you want Claude to work with

Without a connected repository, Claude Code sessions won't start.

Step 4: Choose Your Routing Mode

This is where it gets interesting for marketers. Navigate to the Claude App Home in Slack and find the Routing Mode setting.

Recommendation for growth marketers: Start with Code + Chat. This lets you use one @Claude mention for everything—content generation, data analysis, and actual coding tasks. If Claude routes incorrectly, you can click "Retry as Code" or switch to chat.

Step 5: Add Claude to Channels

Claude is not automatically added to any channels after installation. You must explicitly invite it.

1. Go to the channel where you want to use Claude (e.g., #growth-marketing)

2. Type /invite @Claude and press Enter

3. Claude can now respond to @mentions in that channel

Access control tip: Admins can restrict Claude Code usage by managing which channels Claude is invited to and who has access to those channels. Private channels work too.

Step 6: Test Your First Request

Send your first coding request:

@Claude Create a Python script that reads a CSV of campaign data
and generates a summary report with top-performing channels,
average CPA, and week-over-week trends

Claude will detect the coding intent, create a session, and start working. You'll see progress updates in your Slack thread and a completion summary when done.

How Context Gathering Works

Claude doesn't just read your single message. It gathers context intelligently:

• From threads: When you @mention Claude in a thread, it reads all messages in that thread to understand the full conversation

• From channels: When mentioned directly in a channel, Claude looks at recent channel messages for relevant context

This means if your team is discussing a bug in campaign tracking or a new landing page requirement, Claude picks up that context automatically.

Note: Claude may follow directions from other messages in the context. Only use Claude in trusted Slack conversations.

Practical Use Cases for Growth Marketers

Use Case 1: Campaign Data Analysis Scripts

@Claude Write a script that pulls our Google Ads data from this CSV
[paste data] and identifies which ad groups have CPA above $50
with fewer than 10 conversions. Output a recommended kill list

Claude creates a working script, posts progress, and delivers the output—all from Slack.

Use Case 2: Custom Dashboard Code

@Claude Build an HTML dashboard that visualizes our monthly
marketing metrics. Include charts for: traffic by source,
conversion funnel, and MQL-to-SQL ratio. Use Chart.js

Use Case 3: A/B Test Analysis

@Claude Analyze this A/B test data [paste CSV] and calculate
statistical significance for each variant. Tell me which
variants we can confidently call winners at 95% confidence

Use Case 4: Marketing Automation Scripts

@Claude Create a script that reads a Google Sheet of blog posts,
checks each URL for broken links, and outputs a report of
pages that need fixing

Use Case 5: Collaborative Bug Fixing

When your team reports a tracking issue in Slack, reply in the thread:

@Claude Investigate why our UTM parameters are being stripped
on redirect. Check the redirect logic and suggest a fix

Claude uses the full thread context—error messages, reproduction steps, team observations—to inform its approach.

UI Elements You'll Use

Once Claude completes a task, you'll see action buttons in Slack:

• View Session — Opens the full Claude Code session in your browser with complete transcript and code changes

• Create PR — Creates a pull request directly from the session's changes

• Retry as Code — If Claude responded as chat but you wanted a coding session

• Change Repo — Select a different repository if Claude chose incorrectly

Best Practices

Writing Effective Requests

• Be specific: Include file names, function names, or error messages

• Provide context: Mention the repository or project if it's not obvious

• Define success: Tell Claude what "done" looks like—should it write tests? Create a PR? Generate output?

• Use threads: Reply in threads when discussing bugs or features so Claude gathers the full context

When to Use Slack vs. the Web

Use Slack when:

• Context already exists in a Slack discussion

• You want to kick off a task asynchronously

• Teammates need visibility into the work

Use the web directly when:

• You need to upload files

• You want real-time interaction during development

• You're working on longer, more complex tasks

Troubleshooting

Sessions Not Starting

1. Verify your Claude account is connected in the Claude App Home

2. Check that Claude Code on the web access is enabled

3. Ensure you have at least one GitHub repository connected

Repository Not Showing

1. Connect the repository at claude.ai/code

2. Verify your GitHub permissions

3. Try disconnecting and reconnecting your GitHub account

Wrong Repository Selected

1. Click "Change Repo" to select a different repository

2. Include the repository name in your request for more accurate selection

Authentication Errors

1. Disconnect and reconnect your Claude account in the App Home

2. Ensure you're signed into the correct Claude account in your browser

3. Verify your Claude plan includes Claude Code access

Current Limitations

• GitHub only — Currently supports repositories on GitHub (no GitLab or Bitbucket)

• One PR at a time — Each session can create one pull request

• Rate limits apply — Sessions use your individual Claude plan's rate limits

• Channels only — Works in public and private channels, not in DMs

• Web access required — Users without Claude Code web access only get standard chat responses

Security and Access Controls

Claude Code in Slack is built with enterprise-grade access controls:

• User-level: Each user runs sessions under their own Claude account with their own rate limits and repository access

• Workspace-level: Admins control app installation and can remove access for all users instantly

• Channel-level: Claude only works in channels it's been invited to, giving admins granular control

• Session visibility: For Enterprise and Teams accounts, sessions created from Slack are automatically visible to the organization
