Description

WP Category Toolkit automates mapping content topics to your WordPress category IDs using your WordPress REST API and a GPT-5mini model.

It replaces manual copy-paste and guesswork when assigning categories, speeds up publishing, and reduces tagging errors so your site stays organized and search friendly without you learning new dev magic (just a bit of prompt craft).

💡 Why Use WP Category Toolkit?

• Saves time: Cuts hours of manual category lookup and mapping—deploy batches of posts in minutes, not coffee breaks.
• Stops messy tagging: Eliminates inconsistent category assignments so your archive and SEO behave themselves.
• Measurable improvement: Expect faster publish cycles and fewer category fixes (reduce manual mapping errors by ~90%).
• Competitive edge: Uses an LLM to interpret topic intent, so your categories align with content meaning, not guesswork—like having a librarian who understands your jokes.

⚡ Perfect For

• Content Managers: Keep large WordPress catalogs neat without the spreadsheet gymnastics.
• Agencies: Onboard client sites faster by automating taxonomy mapping across projects.
• Developers & Automators: Add an LLM-powered mapping step to content pipelines without building custom classifiers.

🔧 How It Works

1. ⏱ Trigger: Manual start (kick it off when you’re ready to map categories).
2. 📎 Process: Pull all site categories from your WordPress REST endpoint, aggregate the list, and feed the source content + current topic into the mapping step.
3. 🤖 Smart Logic: A Chain LLM node (Category-Mapping) uses a small prompt to decide which WordPress category IDs match the content topic (GPT5-mini handles the reasoning).
4. 💌 Output: A clean category ID mapping you can paste into your Body Post WordPress node or use to patch posts automatically.

🔐 Quick Setup

1. Import JSON file to your n8n instances → n8n Import Link
2. Add credentials: WordPress API credential & Azure OpenAI (GPT5-mini) credential or you can use usual open AI node
3. Update: Replace the WP endpoint URLand any post-body endpoints you’ll write back to
4. Test: Run with a sample post and copy the output mapping into your Body Post WordPress node to confirm IDs match expected categories

🧩 You’ll Need

• Active n8n instances → n8n Partner Link
• WordPress REST API access and credentials (wp-json access)
• Azure OpenAI account with access to GPT5-mini
• Integrations: WordPress API node, Chain LLM / Azure OpenAI node
• (Optional) Staging WordPress site to test mappings safely

🛠️ Level Up Ideas

• Auto-write category descriptions based on mapped content using the LLM. (It’ll sound smarter than your coffee.)
• Patch posts automatically after mapping so mapping becomes truly zero-touch.
• Add fallback heuristics: if the LLM is uncertain, route to a Slack/Microsoft Teams approval step.
