[BillMartin]

In this article, I will be sharing the ten (10) useful steps on how to become a ServiceNow Developer

Becoming a skilled ServiceNow developer involves not just mastering the platform's technical aspects but also understanding its architecture, best practices, and the ecosystem it operates in.

Here's ten useful steps to help you get started and excel as a ServiceNow developer:

Step 1: Understand ServiceNow Fundamentals

ServiceNow is a cloud-based platform primarily used for IT Service Management (ITSM), but its capabilities extend to other areas such as IT Operations, HR, security operations, and more. To become proficient, it’s important to have a strong foundation in its core modules and processes.

• Learn ITIL: Since ServiceNow is built around ITIL (Information Technology Infrastructure Library) processes, understanding ITIL frameworks (incident, problem, change management, etc.) is essential.
• Familiarize Yourself with ServiceNow Platform: Gain a basic understanding of the ServiceNow UI, forms, lists, and tables. Learn how different modules interact.

Step 2: Get ServiceNow Training

Start with official training from ServiceNow. These are some of the courses that can help you learn the platform effectively:

• ServiceNow Fundamentals: This is a foundational course that introduces the platform and its core capabilities.
• System Administration Certification: This certification helps you learn ServiceNow's key functionalities and how to manage instances.
• Application Developer Course: This course teaches you how to build custom applications on the platform using its development tools.

Step 3: Practice Hands-On

To become a good developer, hands-on experience is crucial. You can request a free personal developer instance from the ServiceNow Developer Portal to practice.

• Personal Developer Instance: ServiceNow provides free personal instances to developers where you can experiment with different features, build custom apps, and troubleshoot issues without fear of breaking anything in production.

  Some hands-on activities to try:

  • Create custom applications: Practice building custom tables, modules, and fields.
  • Scripting in ServiceNow: Practice client-side scripting (using GlideForm), server-side scripting (using GlideRecord), and other business logic through business rules, script includes, and UI actions.

Step 4: Learn Scripting

Proficiency in JavaScript is essential, as it’s the primary scripting language used in ServiceNow.

• Client-Side Scripting: Learn GlideForm, GlideAjax, and other client-side APIs.
• Server-Side Scripting: Understand how to use GlideRecord, GlideSystem, and other server-side scripting tools for data manipulation and business logic.

Practice writing Business Rules, Script Includes, UI Actions, and other Server-side Scripts. You should also get familiar with asynchronous scripts, especially when dealing with APIs and integration with other systems.

Step 5: Master Workflows and Automations

Workflows are central to ServiceNow's automation capabilities.

• Learn Flow Designer: ServiceNow’s Flow Designer enables you to automate processes without code using simple drag-and-drop logic.
• Orchestration and Integration: Explore ServiceNow’s orchestration capabilities to automate tasks across various IT systems. Learn how to integrate third-party systems using REST and SOAP APIs.

Step 6: Understand UI/UX and Customization

ServiceNow allows a high degree of customization. As a developer, you'll need to create user-friendly forms, portals, and dashboards.

• Service Portal: Learn how to create custom Service Portals for user-friendly interfaces.
• UI Pages and Macros: Get familiar with building custom UIs and modifying existing ones.

Step 7: Get Familiar with APIs and Integrations

A good ServiceNow developer must know how to integrate ServiceNow with other systems, which usually involves working with APIs.

• REST and SOAP APIs: Understand how to consume external APIs and expose ServiceNow APIs for other systems to use.
• MID Servers: Learn how to use ServiceNow's MID servers for secure communication with external services behind firewalls.
• Import Sets and Transform Maps: Work on importing data from external sources and mapping it to the ServiceNow database.

Step 8: Learn Security, Governance, and Best Practices

Security and governance are critical to ServiceNow implementations, especially when dealing with sensitive data or large organizations.

• Roles and ACLs: Understand how to manage user roles and access controls within ServiceNow to ensure data integrity and security.
• Data Policies and Scripted Policies: Implement policies to control data input and ensure data quality.
• Performance Best Practices: Learn about query efficiency, optimizing scripts, and minimizing impact on system performance.

Step 9: Prepare for Certifications

ServiceNow offers various certifications that can help validate your skills:

• Certified Application Developer (CAD): This certification is key for proving your ability to build and customize applications in ServiceNow.
• Certified Implementation Specialist (CIS): Specialize in specific ServiceNow modules like ITSM, HR, Security Operations, or IT Operations.
• Certified Technical Architect (CTA): For advanced professionals, this certification helps you demonstrate proficiency in designing and managing ServiceNow deployments.

Step 10: Stay Updated and Engage with the Community

ServiceNow evolves with new releases every six months. Stay updated with new features, best practices, and enhancements through:

• ServiceNow Developer Blog: Follow for updates on new releases, best practices, and community updates.
• Community Forums: Engage with the community to solve problems and share knowledge.
• ServiceNow Knowledge Conferences: Attend ServiceNow's annual conferences to learn about the latest trends, features, and network with other professionals.

Additional Tips:

• Understand Agile and DevOps: ServiceNow often aligns with Agile project management and DevOps practices.
• Work on Real Projects: Get involved in real-world ServiceNow projects. Whether through your current job, freelancing, or internships, hands-on experience will give you insights that no textbook can offer.
• Soft Skills: Communicate effectively with stakeholders to understand their needs and translate them into ServiceNow solutions.

By following these steps, you’ll be well on your way to becoming a proficient ServiceNow developer.

When I first entered the ServiceNow ecosystem, I wasn’t just learning a new platform. I was reshaping how I thought about building enterprise solutions.

Too often, aspiring developers are told to “just start with the basics” without understanding why those fundamentals matter or how they connect to real-world outcomes. That’s why so many get stuck, not because they can’t code, but because they lack a guided path built on relevance, purpose, and clarity.

Here’s the truth: becoming a ServiceNow Developer isn’t about memorizing GlideRecord methods or writing the perfect Script Include from day one. It’s about learning how to solve problems in a structured, scalable way that businesses care about. It’s about designing solutions that don’t just work, they last.

The demand for ServiceNow developers has never been higher. But the path to mastery still requires focused guidance, practical exposure, and real examples that go beyond theory.

That’s exactly why I created this full YouTube playlist  to give developers, architects, and technical professionals a complete, practical roadmap to building confidently on the ServiceNow platform.

If you're serious about becoming a ServiceNow Developer — not just learning, but actually building solutions that matter,  this is where you start:
