Prerequisites

Before diving into automation, let's make sure you have everything ready. Proper preparation ensures a smooth setup process and prevents issues down the road.

What You Need

1. A Shopify Store (Any Plan)

Leon Theme Scheduler works with all Shopify plans – Basic, Shopify, Advanced, and Plus. You don't need any special features or higher-tier plans to automate theme changes.

2. At Least Two Themes

You need a minimum of two themes to schedule changes between them:

• Your current live theme (the one customers see now)
• At least one additional theme to switch to

How to check your themes:

1. Go to Shopify Admin → Online Store → Themes
2. You'll see your "Current theme" at the top
3. Below that, you'll find your "Theme library" with additional themes

Don't have multiple themes? Here's how to add one:

• Click "Add theme" in your theme library
• Choose from free Shopify themes, or upload a purchased theme
• Customize it for your campaign before scheduling

3. Theme Names (Clear and Descriptive)

Before automating, rename your themes so they're easy to identify:

Bad names:

• "Dawn"
• "Copy of Dawn"
• "New theme"

Good names:

• "Default_2025"
• "BlackFriday_2025"
• "Holiday_Christmas_2025"
• "Summer_Sale_2025"

To rename a theme:

1. Go to Online Store → Themes
2. Click the "..." menu next to any theme
3. Select "Rename"
4. Enter a descriptive name

4. Your Campaign Calendar

Know what you want to automate. Before setting up schedules, document:

Campaign	Theme Name	Start Date	Start Time	End Date	End Time
Black Friday	BlackFriday_2025	Nov 24, 2025	12:00 AM	Nov 26, 2025	11:59 PM
Holiday Sale	Holiday_2025	Dec 1, 2025	8:00 AM	Dec 26, 2025	8:00 AM

Having this ready makes the setup process much faster.

5. Admin Access

You need Shopify admin permissions to install apps and modify themes. If you're not the store owner, ensure you have "Apps" and "Themes" permissions in your staff account.

---

Setting Up Leon Theme Scheduler

Now let's install and configure Leon Theme Scheduler. The entire process takes about 10 minutes.

Step 1: Install Leon from the Shopify App Store

1. Open the Shopify App Store

   • Go to apps.shopify.com
   • Or from your Shopify Admin: Apps → Visit Shopify App Store

2. Search for "Leon Theme Scheduler"

   • Type "Leon Theme Scheduler" in the search bar
   • Look for the official Leon app (verified by Shopify)

3. Click "Add app"

   • Review the app's permissions
   • Click "Install app" to proceed

4. Grant Permissions Leon requires access to:

   • Themes: To read and publish themes
   • Store information: To identify your store

   These are standard permissions required for theme automation. Click "Install" to grant access.

Step 2: Complete the Onboarding

After installation, Leon guides you through a quick onboarding process:

1. Welcome Screen

   • Read the brief introduction
   • Click "Get Started"

2. Theme Detection

   • Leon automatically scans your available themes
   • Verify that all your themes appear in the list
   • If a theme is missing, go back to Shopify and ensure it's in your theme library

3. Timezone Configuration

   • Select your store's primary timezone
   • This is critical for accurate scheduling
   • If you serve global customers, choose the timezone of your primary market

4. Notification Preferences

   • Enter your email for schedule notifications
   • Optionally connect Slack or WhatsApp for real-time alerts
   • We recommend enabling at least email notifications

Step 3: Explore the Dashboard

Once onboarding is complete, you'll see the Leon dashboard with these key areas:

• Schedules: View and manage all your scheduled theme changes
• Calendar: Visual overview of upcoming changes
• Themes: List of available themes in your store
• Settings: Configure notifications, timezone, and preferences
• History: Audit log of all past theme changes

Take a moment to familiarize yourself with the interface before creating your first schedule.

Creating Your First Schedule

Let's create your first automated theme schedule. We'll walk through a common scenario: scheduling a promotional theme.

Scenario: Weekend Flash Sale

You want to:

• Switch to your "Flash_Sale" theme on Friday at 6:00 PM
• Automatically revert to your "Default" theme on Monday at 8:00 AM

Step-by-Step Instructions

Step 1: Click "Create Schedule"

From the Leon dashboard:

1. Click the "Create Schedule" button (or "+" icon)
2. A new schedule form opens

Step 2: Name Your Schedule

Enter a descriptive name:

• Schedule Name: "Weekend Flash Sale - January 2025"

Good naming conventions include the event type and date for easy identification later.

Step 3: Select the Theme to Activate

1. Click the "Select Theme" dropdown
2. Choose "Flash_Sale" from your available themes
3. Leon shows a preview of the selected theme

Pro Tip: If you don't see your theme, click "Refresh Themes" to sync with Shopify.

Step 4: Set the Start Date and Time

1. Start Date: Click the date picker and select your Friday date
2. Start Time: Enter "6:00 PM" (or use the time picker)
3. Timezone: Verify it shows your correct timezone

The dashboard shows exactly when this change will occur in your local time.

Step 5: Configure the End (Revert) Settings

This is where automation really shines. Instead of remembering to change back:

1. Enable "Auto-Revert": Toggle this on
2. End Date: Select your Monday date
3. End Time: Enter "8:00 AM"
4. Revert Theme: Select "Default" (or your regular theme)

When the end time arrives, Leon automatically switches back to your default theme.

Step 6: Set Up Notifications

Choose how you want to be notified:

• Before activation: Get a reminder 1 hour before (recommended)
• On activation: Instant notification when theme goes live
• On revert: Notification when theme reverts to default
• On error: Alert if something goes wrong (always enable this)

Step 7: Review and Confirm

Before saving:

1. Review the summary: Leon shows exactly what will happen and when
2. Check the timezone: Verify times are in your expected timezone
3. Preview the theme: Click "Preview" to see what customers will see

If everything looks correct, click "Create Schedule".

Step 8: Verify in Calendar View

After creation:

1. Go to the Calendar tab
2. Find your scheduled dates
3. You'll see visual indicators for:
   • Green: Theme activation
   • Blue: Theme revert
   • Yellow: Upcoming (within 24 hours)

Your first schedule is now active. Leon will handle everything automatically.

Advanced Features

Once you're comfortable with basic scheduling, explore these powerful features to maximize automation.

Sequences: Chain Multiple Theme Changes

Sequences let you create complex campaign flows with multiple theme changes in order.

Example: Black Friday Campaign Sequence

Instead of creating 4 separate schedules:

1. Create a Sequence: Click "New Sequence"

2. Add Steps:

   • Step 1: "Coming Soon" theme → Nov 20, 8:00 AM
   • Step 2: "Black Friday Live" theme → Nov 24, 12:00 AM
   • Step 3: "Cyber Monday" theme → Nov 27, 12:00 AM
   • Step 4: "Default" theme → Nov 28, 8:00 AM

3. Link the Steps: Leon automatically chains them together

4. One-Click Activation: Enable the entire sequence at once

Sequences ensure perfect timing across multi-day campaigns without managing individual schedules.

Timezone Intelligence

For stores serving international customers:

1. Go to Settings → Timezone
2. Enable "Multi-Timezone Display"
3. When creating schedules, you'll see:
   • Your local time
   • UTC time
   • Key market times (US, UK, EU, etc.)

This prevents mistakes when coordinating global campaigns.

Theme Preview Before Going Live

Never publish a broken theme:

1. From any schedule, click "Preview Theme"
2. Leon generates a private preview link
3. Share with your team for approval
4. Preview works on desktop and mobile
5. Test all pages (homepage, collections, product pages, cart)

Only activate schedules after preview approval.

Pause and Resume

Need to delay a scheduled change?

1. Find the schedule in your list
2. Click "Pause"
3. The schedule freezes – won't execute until resumed
4. Click "Resume" when ready

This is useful for last-minute campaign delays without deleting your work.

Duplicate Schedules

Running similar campaigns?

1. Find an existing schedule
2. Click "Duplicate"
3. Modify the dates for your new campaign
4. Save – you've created a new schedule in seconds

Perfect for recurring promotions like monthly sales.

API Access (For Developers)

If you need programmatic control:

1. Go to Settings → API
2. Generate an API key
3. Use the REST API to:
   • Create schedules programmatically
   • Integrate with your marketing automation
   • Build custom dashboards

API documentation is available in the Leon developer portal.

Testing & Launching

Before your first real campaign, test thoroughly to ensure everything works as expected.

Pre-Launch Testing Checklist

1. Create a Test Schedule

2. Verify Theme Appearance

After the test change:

• Open your store in a new browser window

Launch Day Best Practices

When it's time for your real campaign:

   • Verify schedule details are correct
   • Confirm theme is finalized and tested

2. Team Communication

   • Alert your team about the scheduled change
   • Share the exact time it will go live
   • Designate someone to monitor

3. Monitor the Change

   • Be available when the schedule executes
   • Check your store immediately after activation

4. Post-Launch Check

   • Verify all pages look correct
   • Test the checkout flow
   • Check mobile experience
   • Monitor for customer complaints

Troubleshooting Common Issues

Even with automation, occasional issues can occur. Here's how to resolve the most common problems.

Issue 1: Theme Didn't Change at Scheduled Time

Possible causes:

• Timezone mismatch
• Schedule was paused
• App permissions were revoked

Solution:

1. Check the History log for error messages
2. Verify your timezone settings
3. Confirm the schedule status is "Active" (not Paused)
4. Go to Shopify Admin → Apps and verify Leon still has permissions
5. Try a manual test schedule

Issue 2: Wrong Theme Activated

Possible causes:

• Selected wrong theme when creating schedule
• Theme was renamed after schedule creation
• Multiple schedules conflict

Solution:

1. Check which theme was actually selected in the schedule
2. Verify theme names in Shopify match Leon
3. Look for overlapping schedules in Calendar view
4. Edit the schedule to select the correct theme

Issue 3: Notifications Not Arriving

Possible causes:

• Email in spam folder
• Slack integration disconnected
• Notifications disabled

Solution:

1. Check spam/junk folders
2. Go to Settings → Notifications and verify settings
3. Re-enter your email or reconnect Slack
4. Send a test notification

Issue 4: Theme Looks Different Than Expected

Possible causes:

• Theme was modified after scheduling
• Shopify cache serving old version
• Browser cache

Solution:

1. Clear your browser cache and reload
2. Check the theme in Shopify Editor – was it modified?
3. Try viewing in incognito/private browsing mode
4. If needed, re-publish the theme manually to force update

Issue 5: Can't See All Themes

Possible causes:

• Theme sync delay
• Theme was deleted from Shopify

Solution:

1. In Leon, click "Refresh Themes" to re-sync
2. Verify the theme exists in Shopify's theme library
3. Wait 2-3 minutes and try again
4. If still missing, reinstall the theme in Shopify

Frequently Asked Questions

Q: Does automating theme changes affect my store's loading speed?

A: No. Leon changes your theme using Shopify's native theme publishing system. There's no performance overhead – it's the same as if you manually published the theme.

Q: Can I schedule changes for a specific collection or page only?

A: Theme scheduling applies store-wide. For page-specific changes, use Shopify's built-in section templates or a page builder app. Leon focuses on complete theme changes.

Q: What happens if I'm editing a theme when it's scheduled to change?

A: The scheduled theme will still activate. Your edits to the current theme won't be lost – they'll be there when you switch back. However, we recommend avoiding active edits near scheduled change times.

Q: Can I schedule the same theme to activate multiple times?

A: Yes. You can create multiple schedules using the same theme. For example, schedule your "Sale" theme for every weekend of the month with separate start/end times.

Q: Is there a limit to how many schedules I can create?

A: Limits depend on your plan:

• Starter: 5 active schedules
• Pro: 25 active schedules
• Business: Unlimited schedules

Past (completed) schedules don't count toward your limit.

Q: What happens to my schedule if I uninstall Leon?

A: If you uninstall Leon, all schedules are cancelled immediately. Your themes remain untouched – nothing changes without Leon active. If you reinstall, you'll need to recreate your schedules.

Q: Can multiple team members manage schedules?

A: Yes. Anyone with Shopify admin access can use Leon. All actions are logged with the user who performed them for accountability.
