How can you implement a custom checkout workflow in Salesforce Commerce Cloud?

Implementing a custom checkout workflow in Salesforce Commerce Cloud involves the customization of the checkout process itself to meet specific business needs. This is achieved by modifying the checkout controller and ISML templates.

The checkout controller is responsible for managing the flow of the checkout process, including actions such as capturing user input, validating it, and orchestrating the various steps (like billing, shipping, and payment). By customizing this controller, developers can add functionality or change existing behaviors to align with their unique business requirements.

ISML (Interchangeable Server Markup Language) templates allow for the user interface of the checkout process to be personalized. Developers can adjust the front-end presentation, ensuring that the checkout experience reflects the brand's design and aligns with user expectations. This includes accommodating elements such as custom fields, error messages, and overall layout.

This approach provides complete control over the checkout experience, allowing for seamless integration of business-specific logic and an optimized user interface.

Configuring firewall settings relates more to security and access management rather than the functionality of the checkout workflow. Limiting user accounts affects user access
