Complete reference for building AI-powered workflow automations with Zelaxy
Zelaxy Documentation
Zelaxy is an AI-powered workflow automation platform built on a modular, block-based architecture. You connect blocks on a visual canvas — each block performs a specific function — to create powerful automation pipelines without writing code.
How It Works
Every workflow in Zelaxy follows the same pattern:
- A trigger or starter initiates the workflow (user input, webhook, schedule, or event)
- Blocks process data — AI agents reason, conditions branch, tools fetch or send data
- Outputs flow between blocks using
{{blockName.outputField}}references - A response block (optional) returns the final result to the user
Core Concepts
| Concept | Description |
|---|---|
| Blocks | Self-contained processing units you drag onto the canvas. Each has inputs, configuration, and outputs. |
| Connections | Lines between blocks that define data flow. A block's output becomes the next block's input. |
| Variables | Reference any block's output with {{blockName.fieldName}} syntax — works everywhere. |
| Tools | External service integrations (Slack, Gmail, GitHub, etc.) that blocks can call. |
| Triggers | Events that start workflows automatically — webhooks, schedules, or service events. |
Example: Customer Support Bot
Here's a simple workflow that auto-responds to support emails:
[Gmail Trigger] → [Agent Block] → [Condition Block] → [Gmail Send] / [Slack Notify]- Gmail Trigger fires when a new email arrives
- Agent Block (GPT-4o) analyzes the email: classifies urgency, drafts a reply
- Condition Block checks
{{agent.content}}for urgency level - If urgent → Slack notifies the team; otherwise → Gmail sends the auto-reply
