Salesforce Developer
Certifications

Build on the platform with Apex, LWC, and the API

Developer credentials test Apex, Lightning Web Components, the data model, governor limits, testing, and deployment. They assume you can read and reason about code rather than just configure declaratively.

Which Salesforce Developer certification should I start with?

Take Platform Developer first. Platform Developer II builds directly on it and is meaningfully harder, and JavaScript Developer is a parallel track worth adding if you spend most of your time in the front end.
