Okta Certified Developer study guide
Okta Certified Developer · Work through your exam, one topic at a time.
The Okta Certified Developer credential is one of the professional-level certifications in the Okta certification program, positioned alongside the Professional, Administrator, and Consultant tracks. Okta describes it as demonstrating "technical proficiency in building secure, seamless experiences using Okta APIs and SDKs," and it lists no prerequisites, so you can sit it without holding an earlier Okta credential. It suits developers, integration engineers, and identity architects who write code against Okta rather than only administering a tenant. Okta's certification page groups the Developer credential with a study guide and separate exam details, both of which are the authoritative place to confirm current domain coverage, since Okta does not publish the blueprint directly on the overview page. The Okta Certified Developer study guide has 4 sections and about 1,709 words.

This domain covers turning an application into an Okta-integrated app: choosing the protocol, filling in the correct SAML or OIDC settings, assigning users, and pushing lifecycle changes downstream. OIDC/OAuth 2.0 for modern web, SPA, native and service apps.
421 words, about 2 min04User Management and Lifecycle
This domain tests the Users, Groups, hooks and System Log APIs: creating users in the right state, moving them through the lifecycle legally, updating profiles without data loss, and automating group membership. POST /api/v1/users takes a profile (with a unique, email-shaped login ) and optional credentials .
