Petriflow 101 - Tutorials Overview

Welcome to Petriflow 101 - your first guided journey into building low-code, object-centric workflows using and .

What you'll build

Showcase of a Request Application

Built in the low-code language Petriflow, based on Petri Nets and Object-Centric Processes with dynamic Forms.

A simple web form where anyone can submit: Name, Surname, Email (required), Phone, Request text (required), and an Attachment.

The request is then processed step-by-step through:

1. Registration Desk – employee reviews and routes the request
2. Legal Department – lawyer adds a statement (required)
3. PR Department – employee writes a polite reply

Throughout the process, the user can track the status and see the final answer.

Complete Tutorial Series

1️⃣ Creating the First Form

Design the initial Request Form in Netgrif Builder. Define fields, build a 4-column layout, and prepare your first PetriFlow XML.

2️⃣ First Deployment in eTask

Deploy your form to eTask and test it live — both as an anonymous and logged-in user.

3️⃣ Rapid Change & Redeployment

Add validation to your form and redeploy instantly. Learn how version control keeps Builder ↔ eTask in sync.

4️⃣ Workflow — Object-Centric Process

Create your first workflow with places, transitions, and arcs. Understand how Petri Nets represent real business flows.

5️⃣ Roles & Permissions

Define process roles, assign permissions to tasks, and configure Default & Anonymous roles for public access.

6️⃣ Task Forms & Form Reuse

Create task-specific forms and reuse your main Request Form via taskRef attributes to build modular, consistent UIs.

7️⃣ Actions & Low-Code Programming

Add visual low-code logic: update fields, trigger behaviours, and automate paths using assignTask() finishTask().

8️⃣ Final Deployment & Testing

Update metadata, set auto assignment, deploy your final process, and perform end-to-end testing in eTask.

Learning goals

By following the complete Petriflow 101 series, you’ll learn how to:

• Visually model workflows and data-driven forms
• Deploy and version processes in eTask
• Implement logic using low-code actions
• Combine forms, roles, and transitions into object-centric applications
• Build fully functional web apps without writing full code
