API topics, including users, conversations, notifications, agent chat, and analytics APIs, typically represent a significant portion of the exam. Authentication and resource management are equally critical because they underpin secure API integration. Expect roughly 40-50% of questions to focus on API design, implementation, and troubleshooting.
Authentication determines which APIs your application can access and what data it can retrieve. You must implement OAuth 2.0 tokens correctly, manage token expiration, and ensure your API calls include proper authorization headers. In practice, a misconfigured authentication setup will block all downstream API calls, so this is foundational for any integration work.
Ideally, you should have made at least 5-10 real API calls using the Genesys Cloud CX SDK or REST endpoints. Hands-on experience helps you understand payload structures, error responses, and rate-limiting behavior far better than reading alone. If you lack access to a production environment, use a sandbox or demo org to practice authentication, query conversation data, and retrieve recordings.
Many candidates confuse role-based permissions with API resource scopes, leading to incorrect answers about access control. Others rush through scenario questions without fully reading the context, missing critical details about integration requirements. Additionally, underestimating the depth of API knowledge needed, thinking it is just "call an endpoint", leads to weak performance on questions about error handling, pagination, and event-driven workflows.
Review your weak topic areas and take a full-length timed practice test to assess readiness. Spend time on scenario-based questions and ensure you understand how platform features interact, such as how scripting integrates with quality management or how notification APIs feed real-time data to external systems. Avoid cramming new topics; instead, reinforce your understanding of connections and practice pacing so you finish the exam on time.
