Who Should Take This

  • The Aspiring Developer: You have a solid grasp of object-oriented programming (Java, C#, JavaScript) and want to transition into the Salesforce ecosystem.
  • The Power Admin: You’ve hit the limits of Flow and Formula Fields and are ready to master Apex, SOQL, and Lightning Web Components.
  • The Technical Consultant: You design solutions and need to know exactly when to recommend custom code over declarative configuration.

What You’ll Prove

This credential validates your ability to develop and deploy custom business logic and interfaces using the programmatic capabilities of the Lightning Platform. It’s not just about syntax; it’s about knowing the “Salesforce Way” of solving problems. * You can implement complex business logic using Apex triggers, classes, and asynchronous processing.

  • You can design efficient data queries using SOQL and SOSL while respecting multi-tenant governor limits.
  • You can build modern, reactive user interfaces using the Lightning Web Component (LWC) framework.
  • You can write robust unit tests and use the Salesforce CLI to manage the application lifecycle.

Exam Outline

Domain Weight What’s Covered
Developer Fundamentals 23% MVC pattern, multi-tenancy, core CRM objects, and declarative vs. programmatic decisions.
Process Automation & Logic 30% Apex syntax, variables, control flow, triggers, SOQL, SOSL, and DML operations.
User Interface 25% LWC basics, Aura components, Visualforce pages, and custom styling.
Testing, Debugging & Deployment 22% Test classes, System.assert, debugging tools, Salesforce DX, and deployment environments.

💡 In Notion, convert each domain row into a toggle to nest your study notes underneath.


Suggested Study Path

  1. Master the Fundamentals. Review the Salesforce schema and understand how custom objects relate to one another via Lookup and Master-Detail relationships.
  2. Code in a Sandbox. Don’t just read documentation. Set up a free Developer Edition org and build a custom Apex trigger that processes records in bulk.
  3. Learn to Query. Practice writing SOQL queries in the Developer Console. Ensure you understand how to filter indexed fields to avoid performance bottlenecks.
  4. Prioritize Declarative Tools. Internalize the rule: if you can do it with a Flow, don’t use code. The exam frequently tests your ability to choose the most efficient path.
  5. Study Governor Limits. Memorize the key numbers—100 SOQL queries, 150 DML statements, and the 50,000 record limit for queries.
  6. Run Practice Tests. Use reputable community resources to identify your weak spots in the four main domains before booking your seat.

Watch Out For

  • The “Flow First” Trap: Salesforce heavily pushes declarative solutions. If a question offers a Flow and an Apex Trigger as solutions for a simple update, the Flow is almost always the “correct” answer.
  • Bulkification Failures: Any code snippet that performs a SOQL query or a DML statement inside a for loop is a red flag. These are classic “wrong” answers designed to test your knowledge of multi-tenant limits.
  • Partial Success: Understand the difference between insert (all-or-nothing) and Database.insert(records, false) (partial success). The exam loves to test how errors are handled in bulk operations.
