Pass the Microsoft Power Platform Developer (PL-400) exam on your first attempt — with realistic, pro-developer practice tests.

The PL-400 earns you the Microsoft Certified: Power Platform Developer Associate credential — proof that you can design, develop, secure, and extend solutions across the Microsoft Power Platform using professional development skills. It validates the work that separates a pro developer from a low-code maker: writing plug-ins and custom APIs, extending Dataverse with event-driven logic, building PCF (Power Apps Component Framework) controls, integrating with Azure and external systems, and applying application lifecycle management (ALM). As organizations scale their low-code platforms, developers who can extend them with real code are in high demand.

PL-400 is a genuinely technical, code-aware exam. You'll face 40–60 questions in about 90–120 minutes — including scenario and possible interactive items — that test what you'd actually build: a plug-in registered on the right Dataverse event, a custom API, a webhook or Azure Service Bus integration, a PCF control, or JavaScript against the Client API object model. With "Extend the platform" alone worth 40–45%, plug-in and Dataverse-extensibility depth is decisive. Memorizing won't cut it. The most reliable way to pass is realistic, scenario-driven practice, which is exactly what this course delivers.

Why this certification matters

Low-code is booming, but enterprises still need professional developers to extend it securely and at scale. The PL-400 proves you can do exactly that — combining Power Apps, Power Automate, and Dataverse with C#, JavaScript, and REST integrations. It opens Power Platform developer, Dynamics 365 developer, and solution-engineering roles, complements the maker-level certifications, qualifies as a feeder toward the AB-100 AI architect path, and renews for free each year.

What makes this course different

This is not a recycled, outdated question dump. Every question reflects the current PL-400 skills measured (updated March 2026), weighted to match the real exam — with heavy emphasis on platform extensibility, just like the test. Questions mirror the exam's scenario- and code-aware style with realistic distractors. You don't just learn the right answer — you learn why a synchronous plug-in fits one case and an asynchronous one another, when to use a custom API over an action, or how to choose among webhooks, Service Bus, and Event Hub for integration. That developer reasoning is exactly what the exam tests.

What's included

• A deep bank of realistic, scenario-based practice questions across multiple full-length timed tests

Topics covered

• Extend the platform (40–45%) — plug-ins and the event framework, custom APIs, Dataverse events, webhooks, Azure Service Bus and Event Hub, virtual tables, and server-side extensibility

How the practice tests simulate the real exam

Each test is a full-length, timed set built to match the real exam, weighted toward platform extensibility like the real thing, so you train pacing and developer decision-making together. Take a test, study every explanation, identify your weak domains, and retake until you're consistently scoring 85%+. That benchmark is your green light to book the real exam with confidence.
