3. What is the difference between OCAPI and SCAPI in SFCC?

OCAPI (Open Commerce API): A RESTful API for integrating external systems with SFCC. It supports both data and shop APIs for headless commerce implementations.

SCAPI (Salesforce Commerce API): A legacy SOAP-based API used for integrations. It is being phased out in favor of OCAPI.

  // Example: OCAPI Request
  fetch('/s/-/dw/data/v21_10/products/12345', {
      method: 'GET',
      headers: {
          'Authorization': 'Bearer <access_token>'
      }
  })
  .then(response => response.json())
  .then(data => console.log(data));
  

Key Takeaways:

• OCAPI is the preferred API for modern SFCC integrations.
• SCAPI is legacy and should be avoided for new projects.

4. What is the role of pipelines in SFCC?

Pipelines in SFCC are used to define the flow of logic for processing requests. They consist of a series of nodes and stages that execute specific tasks, such as rendering a page or processing a form submission.

Example:

  // Example: Custom Pipeline
  module.exports = {
      execute: function(req, res, next) {
          // Custom logic here
          next();
      }
  };

• They can be customized to meet specific business requirements.

5. What is the difference between ISML and DSML in SFCC?

ISML (Internet Store Markup Language): A templating language used to render dynamic content in SFCC. It is similar to HTML but includes additional tags for SFCC-specific functionality.

DSML (Demandware Script Markup Language): A legacy templating language that is no longer used in modern SFCC implementations.

  
  <isif condition="${pdict.product}">
      <h1>${pdict.product.name}</h1>
  </isif>
  

Key Takeaways:

• ISML is the standard templating language for SFCC.
• DSML is outdated and should not be used.

6. What is the role of controllers in SFCC?

Controllers in SFCC handle the logic for processing requests and generating responses. They are part of the MVC (Model-View-Controller) architecture and are used to manage data flow between the model and the view.

  // Example: Custom Controller
  module.exports = {
      show: function(req, res, next) {
          const product = ProductMgr.getProduct(req.querystring.pid);
          res.render('product/productDetails', { product: product });
      }
  };
  

Key Takeaways:

• Controllers are responsible for handling business logic and rendering views.
• They play a crucial role in the MVC architecture of SFCC.

7. What is the difference between scripts and jobs in SFCC?

Scripts: Small pieces of code executed on-demand or triggered by events. They are used for tasks like data validation or custom logic.

Jobs: Scheduled tasks that run at specific intervals. They are used for batch processing, such as updating product catalogs or generating reports.

  // Example: Script
  const ProductMgr = require('dw/catalog/ProductMgr');
  const product = ProductMgr.getProduct('12345');

  // Example: Custom Cartridge
  module.exports = {
      execute: function(req, res, next) {
          // Custom logic here
          next();
      }
