lastPublishedfield
Phase 5: Verification & Reporting

lastPublishedtimestamp updated - Verify site is accessible at published URL(s)

Guidelines
Phase 1: Critical Requirements
Site Status Check:
- Always fetch complete site details using
sites_get - Compare
lastUpdatedvslastPublishedto detect unpublished changes - If timestamps are identical, inform user "No changes to publish"
- If
lastPublishedis null, warn "First publish - entire site will go live"
Timestamp Handling:
- Store both ISO format and human-readable format
- Calculate time elapsed since last publish
- Show timezone (prefer UTC for clarity)
Phase 2: Change Detection Rules
Page Change Detection:
- Compare page
lastUpdatedwith sitelastPublished - Only flag pages where
lastUpdated > lastPublished - Categorize changes:
- Content changes (hard to detect via API)
- SEO metadata changes (compare if available)
- Structural changes (page created/deleted)
CMS Item Detection:
- Check
isDraftfield for all items - Compare
lastUpdatedwith sitelastPublished - Count items in each state:
- Published + not modified
- Published + modified
- Draft (won't be published)
- Archived (won't appear on site)
Collections to Check:
- Query all collections with
collections_list - For each collection, list items with
collections_items_list_items - Batch queries if site has many collections (10+ collections)
Phase 3: Pre-Publish Validation
Required Checks:
-
Broken References:
- Check if referenced items exist
- Warn if reference field points to deleted/archived item
- Note: API may not expose this easily - best effort
-
Missing Required Fields:
- Verify all required CMS fields are populated
- Warn if required fields are empty (shouldn't be possible, but check)
-
SEO Completeness:
- Check pages for missing
seo.titleorseo.description - Warn but don't block publish
- Provide recommendations for improvement
- Check pages for missing
-
Draft Item Warning:
- Clearly list all draft items
- Explain they will remain unpublished
- Offer to cancel if user wants to publish drafts first
Warning Levels:
- 🔴 Critical: Would break site (broken refs, missing required fields)
- ⚠️ Warning: Suboptimal but publishable (missing SEO, drafts)
- 💡 Suggestion: Best practices (add meta descriptions, optimize images)
When to Block Publish:
- Only block if critical errors found
- For warnings and suggestions, allow user to proceed
- Always show warnings prominently
Phase 4: Confirmation & Publishing
Confirmation Requirements:
- User MUST type "publish" (case-insensitive)
- Do NOT accept: "yes", "y", "ok", "go", "confirm"
- Rationale: Prevents accidental publishes from generic confirmations
- If user types anything else, ask again or treat as cancel
Publish API Usage:
// Correct format for sites_publish
{
"site_id": "site-id-here",
"publishToWebflowSubdomain": true, // or false
"customDomains": [] // MUST be array, even if empty
}
// If custom domains exist:
{
"site_id": "site-id-here",
"publishToWebflowSubdomain": false,
"customDomains": ["example.com", "www.example.com"]
}
Domain Selection:
- If no custom domains: Publish to subdomain only
- If custom domains exist: Ask user which to publish to
- Subdomain only
- Custom domains only
- Both
- Default to subdomain if user doesn't specify
Error Handling:
- If
customDomainsvalidation error: Ensure it's an array - If
400 Bad Request: Check request format - If
403 Forbidden: Check site publish permissions - If
500 Server Error: Retry once after 5 seconds, then report failure
Phase 5: Verification & Reporting
Post-Publish Verification:
-
Fetch Updated Site Info:
- Call
sites_getagain - Verify
lastPublishedtimestamp updated - If timestamp didn't update, publish may have failed
- Call
-
Site Accessibility Check:
- Use WebFetch to check published URL
- Verify site returns 200 OK
- Check that content is served (not error page)
- Measure response time
-
Custom Domain Checks:
- If published to custom domains, verify each domain
- Some domains may take time to propagate (DNS)
- Note: "Domain may take a few minutes to update" if slow
Verification Failure Handling:
- If site not accessible: Report clearly
- Note: Changes ARE published even if verification fails
- Possible causes:
- DNS propagation delay
- CDN cache not yet cleared
- Temporary Webflow infrastructure issue
- Suggest: "Try accessing the site in 2-3 minutes"
Success Report Format:
✅ Published Successfully!
Site: [Site Name]
Published at: [ISO Timestamp] ([Human Readable])
What Went Live:
- X pages modified
- Y CMS items published
- Z draft items promoted to published
Verification:
✅ Site accessible
✅ URL: [primary URL]
✅ Response time: [Xms]
[If custom domains]
Custom Domains:
✅ example.com - accessible
⚠️ www.example.com - propagating (may take 2-3 minutes)
Best Practices
Always:
- ✅ Show comprehensive preview before publishing
- ✅ Require explicit "publish" confirmation
- ✅ Verify site after publish
- ✅ Report exact publish timestamp
- ✅ List all changes going live
- ✅ Warn about draft items
Never:
- ❌ Publish without explicit user confirmation
- ❌ Accept generic confirmations like "yes"
- ❌ Hide warnings from user
- ❌ Retry failed publishes automatically
- ❌ Proceed if critical errors detected

All changes are already published. Your site is up to date!
First Publish (Never Published Before):
⚠️ First Publish Warning
This site has NEVER been published before.
This will make the ENTIRE site publicly accessible:
- All pages (2 pages)
- All CMS items (47 items across 3 collections)
- All assets
Are you ready to make this site live?
Type "publish" to proceed, or "cancel" to abort.
Publish to Staging Subdomain:
- If site has custom domains but user chooses subdomain only
- Useful for testing before publishing to production domain
- Explain: "Publishing to subdomain only. Custom domains will continue showing old version."
Partial Publish Not Supported:
- Webflow publishes entire site, not individual pages
- Cannot publish specific pages or collections
- If user asks to "publish just the homepage", explain limitation
- Alternative: Use staging subdomain for testing
Performance Optimization
For Large Sites:
- Sites with 100+ pages or 1000+ items may take time to analyze
- Show progress: "Analyzing 150 pages..."
- Batch API calls when possible
- Consider skipping detailed diff for very large change sets
Caching:
- Cache site info during workflow (don't refetch unnecessarily)
- Only refetch after publish to verify
Timeouts:
- Publish API may take 10-30 seconds for large sites
- Don't timeout too quickly
- Show: "Publishing... this may take up to 30 seconds for large sites"
