What kind of Salesforce Products Need 2GP 

Discover what kind of Salesforce Products need Second-Generation Packaging (2GP). From complex enterprise solutions to niche ISV offerings, understanding the ideal candidates for 2GP is crucial for maximizing your Salesforce development efforts. 

In this exploration, we’ll highlight the characteristics and use cases that make 2GP a must-have, empowering you to make informed decisions and leverage modern packaging techniques in your Salesforce projects. 

Why 2GP is Essential for Salesforce 

Imagine your Salesforce apps are not only powerful but also agile, adaptable, and scalable. Second generation packages (2GP) in salesforce makes this possible with: 

    • Flexibility: Seamless sharing of Apex source code across packages. 
    • Architectural Freedom: No rigid namespace constraints. 
    • Efficiency: Automation through Salesforce CLI, reducing manual tasks. 

Scenarios Calling for 2GP in Salesforce 

When applications grow, managing them as a single entity becomes impractical. Breaking them into multiple managed packages is often necessary. Salesforce imposes specific dependency rules among package generations: 

1GP to 2GP Dependencies: 

    • 1GP cannot depend on 2GP. 
    • 1GP can depend on other 1GP. 
    • 2GP can depend on other 2GP. 
    • 2GP can depend on 1GP. 

If you plan to enhance revenue by breaking your product into smaller modules for diverse clients, salesforce second generation packaging(2GP) is the ideal approach. 

Example 1: Modular CRM Application with 2GP: Legal Case Management 

Consider a comprehensive customer relationship management (CRM) application for a legal services company. This application can be broken down into dependent packages using custom objects: 

    • Legal Case Management Core Package: Foundation for creating, tracking, and managing legal cases. 
    • Calendar and Appointment Management Package: Integration for scheduling and managing client meetings. 
    • Document Management Package: Upload, share, and collaborate on case-related documents, integrating with systems like Google and SharePoint. 
    • Billing and Invoicing Package: Track billable hours and generate client invoices. 
    • Payment and Financial Management Package (Optional Add-On): Handle client payments, financial transactions, and accounting, integrating with payment gateways like Stripe, PayPal, or Square. 

By breaking down the legal case management application into these dependent packages, the legal services company achieves: 

    • Modular Development: Enhances scalability and customization. 
    • Scalability: Facilitates easy addition of new features or modules. 
    • AppExchange Compatibility: Ensures compatibility with Salesforce’s marketplace. 

Example 2: Utilizing a Shared Namespace 

Using a shared namespace, such as LegalCaseManagement, in the legal case management application offers several benefits: 

    • Organization: Logical grouping of all packages related to the application. 
    • Namespace Clarity: Reduces the risk of namespace collisions and ensures consistent naming conventions. 
    • Package Management: Simplifies deployment, versioning, and dependency resolution. 
    • Dependency Management: Facilitates modular development and reuse of functionalities. 
    • Scalability: Eases the addition of new features or modules as the application grows. 

Benefits of Shared Namespaces with 2GP 

Sharing namespaces with 2GP in Salesforce provides: 

    • Easy Modularity: 2GP allows for modularization by sharing namespaces among multiple packages, making your applications easier to manage and scale. Using the “@namespaceAccessible” annotation, public Apex classes can be shared across packages. 
    • Smooth Operations: Reduces naming conflicts between packages, ensuring smoother operations and fewer errors. 
    • Team Collaboration: Fosters collaboration among development teams, enabling seamless code sharing and consistency across applications. 
    • Tailored Solutions: Flexible customization allows teams to extend functionality across packages while maintaining a clear namespace structure. 
    • Efficient Dependency Management: Simplifies dependency management, ensuring smooth deployment and runtime operations. 

By embracing 2GP to share namespaces, you’re laying the groundwork for scalable, collaborative, and customized Salesforce solutions that drive your business forward. 


Second generation packages(2GP) in salesforce offers unparalleled flexibility, architectural freedom, and streamlined efficiency, making it an ideal choice for modern Salesforce development. Breaking applications into manageable packages and utilizing shared namespaces allows for greater scalability, customization, and team collaboration. Harness the power of 2GP to enhance your Salesforce strategy and drive your business to new heights.
