About

The Salesforce Certified System Architect is a domain-level expert credential that does not require a standalone exam. Instead, it is automatically awarded upon earning all four architect-level designer certifications: Certified Platform Developer I (PDI), Certified Development Lifecycle and Deployment Architect (DLDA), Certified Identity and Access Management Architect (IAM), and Certified Integration Architect. The credential validates expertise in designing scalable, integrated Salesforce solutions with robust security and governance. System Architects focus on off-platform systems integration, identity and access management, deployment governance, and continuous platform modification. The credential is a prerequisite pathway toward the Salesforce Certified Technical Architect (CTA) — the pinnacle of Salesforce certifications.
