The PL-400 exam validates your expertise as a Microsoft Power Platform Developer. This certification confirms your ability to design, build, and extend solutions using the Microsoft Power Platform ecosystem. Whether you're developing custom applications, integrating systems, or enhancing user experiences, this exam tests both theoretical knowledge and practical problem-solving skills. This page provides a structured study roadmap to help you prepare efficiently and confidently.
Use this topic map to guide your study for Microsoft PL-400 (Microsoft Power Platform Developer) within the Microsoft Power Platform path.
The PL-400 exam uses multiple question formats to assess both conceptual understanding and practical decision-making. Questions range from straightforward knowledge checks to complex scenarios that require you to evaluate trade-offs and recommend solutions.
Questions increase in complexity as you progress, with later items often combining multiple topics and requiring you to justify your reasoning based on business context and technical constraints.
An effective study plan aligns your learning to the exam topics and builds confidence through progressive practice. Dedicate time each week to specific domains, then integrate them into realistic scenarios to reinforce connections between concepts.

Build Power Platform Solutions and Develop Integrations usually account for a significant portion of the exam, as they test your ability to assemble complete solutions and connect systems. However, all six topic areas are represented, so balanced preparation across all domains is essential. Review the official exam outline to confirm current weightings.
In practice, you start by creating a technical design based on business needs, then extend the user experience through customized interfaces, extend the platform with custom logic, and develop integrations to link external systems. Finally, you build the complete solution and implement improvements for performance and maintainability. Understanding these connections helps you answer scenario-based questions that blend multiple topics.
Ideally, you should have practical experience building at least one or two end-to-end solutions using Power Apps, Power Automate, and Dataverse. Hands-on labs covering data modeling, form customization, workflow creation, and connector configuration are especially valuable. If you lack direct experience, prioritize sandbox practice and guided tutorials alongside study materials.
Frequent errors include misunderstanding when to use canvas apps versus model-driven apps, overlooking security and compliance considerations in design decisions, and choosing inefficient integration patterns. Many candidates also rush through scenario questions without fully analyzing all requirements, leading to suboptimal answers. Slow down, re-read each question carefully, and consider trade-offs before selecting your response.
Spend the final week reviewing weak topic areas identified in practice tests rather than starting new material. Take one full-length timed mock exam to assess readiness and build confidence. Review explanations for any questions you missed, and refresh your memory on key terminology and decision trees. Avoid cramming new content; instead, consolidate what you already know.
You need to ensure that Adventure Works Cycle can track information from visitors to bike fairs.
What should you create?
By using a Dynamics 365 connector, you can create flows that initiate when an event occurs in Dynamics 365, or some other service, which then performs an action in Dynamics 365, or some other service.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are designing a one-way integration from Microsoft Dataverse to another system.
You must use an Azure Function to update the other system. The integration must send only newly created records to the other system. The solution must support scenarios where a component of the integration is unavailable for more than a few seconds to avoid data loss.
You need to design the integration solution.
Solution: Register a webhook in the Dataverse instance that connects to the Azure Function. Register a step on the webhook which runs synchronously on the record's Create message and in the post-operation stage.
Does the solution meet the goal?
A Power Platform solution includes the following Web API call:
GET http://contoso.crm.dynamics.com/api/data/v9.1/RelationshipDefinitions?$select=SchemaName
You need to explain what this line of code is doing.
What does the code do?
You create a custom API. You define the API as a function.
The custom API does not appear in the response received from https:/ [yourorg]. api.crm.dynamics.com/api/data/v9.2/$metadata and returns an error when called.
You need to identify why the custom API is not working.

An organization has an Azure SQL Database instance that must be synchronized daily with data from Dynamics 365 Sales. A large amount of data might need to be synchronized on some days.
You need to reduce the time required to synchronize data.
Solution:
Enable change tracking for entities that will be synchronized.
Implement a console application that queries for changes.
Does the solution meet the goal?
Instead use the Data Export Service to sync data between the database and Dynamics 365 Sales.
