Overview
About the exam
The PL-400 certification validates skills in designing, developing, testing, and troubleshooting Microsoft Power Platform solutions using code. It covers custom connectors, plug-ins, PCF (PowerApps Component Framework) controls, Azure Functions integration, workflow extensions, Dataverse Web API development, and solution packaging for the Power Platform.
This certification is designed for professional developers who extend the Power Platform beyond low-code capabilities. Candidates should be proficient in JavaScript, C#, TypeScript, or .NET and have experience building custom components, server-side logic, and API integrations that enhance model-driven and canvas apps on the Power Platform.

Where candidates struggle
This exam tests developer-level coding skills for the Power Platform. Candidates from a low-code background who haven't built custom plug-ins, PCF controls, or used the Dataverse Web API often find the technical depth challenging.
- 01Plug-in Development — Not understanding plug-in registration, execution pipeline stages, and transaction management in Dataverse plug-ins.
- 02PCF Controls — Struggling with PowerApps Component Framework lifecycle methods, manifest configuration, and React-based component development.
- 03Custom Connectors — Confusing custom connector authentication types (OAuth2, API Key) and OpenAPI definition requirements for Power Platform.
- 04ALM and Solutions — Overlooking managed vs unmanaged solutions, solution layering, and environment deployment strategies using Azure DevOps.
- 05Web API Usage — Not knowing Dataverse Web API CRUD operations, FetchXML queries, and batch request patterns for server-side integrations.
