Workflow Variables Reference: Every Variable Available in AIWU
Variables are what make AIWU workflows dynamic — instead of static text, your prompts and outputs use live data from WordPress events. This reference guide covers every available variable, how to use them in prompts, and how to combine variables for complex outputs.
Before You Start
You’ll need:
- Familiar with building custom workflows (First Custom Workflow guide)
- AIWU with API key configured
- Time needed: Reference document — bookmark for quick lookups
- Plan required: Free (basic variables) · Pro (conditional logic)
How Variables Work
Variables use curly brace syntax: {variable_name}. When a workflow runs, AIWU replaces each variable with the actual value from the triggering event. A workflow triggered by a WooCommerce order automatically has access to that order’s data — no extra configuration needed.
Variables can be used in:
- AI prompts — to pass event data to the AI for processing
- Output actions — to include real data in messages, emails, or saved content
- Conditions — to create if/then logic based on data values (Pro)

Using Variables in Practice
In an AI prompt:
Write a 3-sentence LinkedIn post about this new article. Title: {post_title}. Excerpt: {post_excerpt}. URL: {post_url}. Include the URL as a call to action at the end.
In an output action (Telegram message):
🆕 New order #{order_id} from {billing_first_name} {billing_last_name}
💰 {order_total} | 📦 {order_items}{ai_output}
Conditional Logic with Variables (Pro)
Use variables in workflow conditions to create branching logic:
{order_total}greater than 100 → send VIP notification to Slack{post_category}equals “Announcements” → also post to LinkedIn{billing_country}equals “US” → send USD-formatted email, else send EUR-formatted email
Add conditions in the workflow builder between trigger and action steps.
