WordPress Publisher
Publish content directly to WordPress sites using the REST API with full Gutenberg block formatting, automatic category selection, SEO tag generation, and preview capabilities.
Complete Workflow Overview
1. CONNECT → Authenticate with WordPress site
2. ANALYZE → Load categories from site, analyze content for best match
3. GENERATE → Create SEO-optimized tags based on content
4. CONVERT → Transform markdown/HTML to Gutenberg blocks
5. PREVIEW → Create draft and verify rendering
6. PUBLISH → Publish or schedule the post
7. VERIFY → Confirm live post renders correctly
Step 1: Connection Setup
Get Credentials
Ask user for:
- WordPress site URL (e.g.,
https://example.com) - WordPress username
- Application password (NOT regular password)
How to Create Application Password
Guide user:
- Go to Users → Profile in WordPress admin
- Scroll to Application Passwords section
- Enter name:
Claude Publisher - Click Add New Application Password
- Copy the generated password (shown only once, with spaces)
Test Connection
from scripts.wp_publisher import WordPressPublisher
wp = WordPressPublisher(
site_url="https://example.com",
username="admin",
password="xxxx xxxx xxxx xxxx xxxx xxxx" # Application password
)
# Test connection
user_info = wp.test_connection()
print(f"Connected as: {user_info['name']}")
Step 2: Load and Select Categories
Auto-Load Categories from Site
# Get all categories from the WordPress site
categories = wp.get_categories_with_details()
# Returns list like:
# [
# {'id': 1, 'name': 'Uncategorized', 'slug': 'uncategorized', 'count': 5},
# {'id': 2, 'name': 'Tutorials', 'slug': 'tutorials', 'count': 12},
# {'id': 3, 'name': 'Cloud Hosting', 'slug': 'cloud-hosting', 'count': 8},
# ]
Smart Category Selection
The system analyzes content and selects the most appropriate category:
# Analyze content and suggest best category
suggested_category = wp.suggest_category(
content=article_content,
title=article_title,
available_categories=categories
)
# Or let user choose from available options
print("Available categories:")
for cat in categories:
print(f" [{cat['id']}] {cat['name']} ({cat['count']} posts)")
Category Selection Logic
- Exact match - Title/content contains category name
- Keyword match - Category slug matches topic keywords
- Parent category - Fall back to broader parent if no match
- Create new - Create category if none fit (with user approval)
Step 3: Generate SEO-Optimized Tags
Automatic Tag Generation
Generate tags that improve Google search visibility:
# Generate tags based on content analysis
tags = wp.generate_seo_tags(
content=article_content,
title=article_title,
max_tags=10
)
# Returns list like:
# ['n8n hosting', 'workflow automation', 'self-hosted n8n',
# 'affordable hosting', 'docker deployment', 'node.js hosting']
Tag Generation Rules
- Primary keyword - Always include as first tag
- Secondary keywords - Include 2-3 related terms
- Long-tail keywords - Include 3-4 specific phrases
- Entity tags - Include product/brand names mentioned
- Topic tags - Include broader category terms
Create/Get Tags in WordPress
# Get or create all tags, returns list of tag IDs
tag_ids = wp.get_or_create_tags(tags)
Step 4: Convert Content to Gutenberg Blocks
Markdown to Gutenberg
from scripts.content_to_gutenberg import convert_to_gutenberg
# Convert markdown content
gutenberg_content = convert_to_gutenberg(markdown_content)
Supported Conversions
| Markdown | Gutenberg Block |
|---|---|
# Heading |
wp:heading |
**bold** |
<strong> in paragraph |
- list item |
wp:list |
1. ordered |
wp:list {"ordered":true} |
\``code```` |
wp:code |
> quote |
wp:quote |
 |
wp:image |
| table | |
wp:table |
Table Conversion (Critical for AI Content)
Tables are converted with proper Gutenberg structure:
# Input markdown:
| Feature | Plan A | Plan B |
|---------|--------|--------|
| Price | $10 | $20 |
# Output Gutenberg:
<!-- wp:table -->
<figure class="wp-block-table"><table>
<thead><tr><th>Feature</th><th>Plan A</th><th>Plan B</th></tr></thead>
<tbody><tr><td>Price</td><td>$10</td><td>$20</td></tr></tbody>
</table></figure>
<!-- /wp:table -->
Step 5: Preview Before Publishing
Create Draft for Preview
# Create as draft first
result = wp.create_draft(
title="Article Title",
content=gutenberg_content,
categories=[category_id],
tags=tag_ids,
excerpt="Auto-generated or custom excerpt"
)
post_id = result['post_id']
preview_url = result['preview_url']
edit_url = result['edit_url']
Verify Preview
# Fetch preview page to verify rendering
preview_content = wp.fetch_preview(post_id)
# Check for issues
issues = wp.validate_rendered_content(preview_content)
if issues:
print("Issues found:")
for issue in issues:
print(f" - {issue}")
Preview Checklist
- Title displays correctly
- All headings render (H2, H3, H4)
- Tables render with proper formatting
- Lists display correctly (bullet and numbered)
- Code blocks have syntax highlighting
- Images load (if any)
- Links are clickable
- Category shows correctly
- Tags display in post
Step 6: Publish the Post
Publish Draft
# After preview approval, publish
result = wp.publish_post(post_id)
live_url = result['live_url']
Or Create and Publish Directly
# Full publish workflow in one call
result = wp.publish_content(
title="Article Title",
content=gutenberg_content,
category_names=["Cloud Hosting"], # By name, auto-resolves to ID
tag_names=["n8n", "hosting", "automation"],
status="publish", # or "draft", "pending", "private", "future"
excerpt="Custom excerpt for SEO",
slug="custom-url-slug"
)
Scheduling Posts
# Schedule for future publication
from datetime import datetime, timedelta
publish_date = datetime.now() + timedelta(days=1)
result = wp.publish_content(
title="Scheduled Post",
content=content,
status="future",
date=publish_date.isoformat()
)
Step 7: Verify Published Post
Check Live Post
# Verify the published post
verification = wp.verify_published_post(post_id)
print(f"Live URL: {verification['url']}")
print(f"Status: {verification['status']}")
print(f"Categories: {verification['categories']}")
print(f"Tags: {verification['tags']}")
Common Issues and Fixes
| Issue | Cause | Solution |
|---|---|---|
| Tables not rendering | Missing figure wrapper | Use proper wp:table block structure |
| Code not highlighted | Missing language attribute | Add {"language":"python"} to code block |
| Images broken | Wrong URL or missing media | Upload to WordPress first, use media ID |
| Tags not showing | Theme doesn't display tags | Check theme settings or use different theme |

print(f"Preview: {draft['preview_url']}")

- Use application passwords - Never use regular WordPress password
- Select appropriate category - Helps with site organization and SEO
- Generate relevant tags - Improves Google discoverability
- Validate Gutenberg blocks - Ensure proper block structure
