Review the Microsoft Power Platform Developer (PL-400) scope, Dataverse customization, plugins, custom connectors, APIs, Power Apps, Power Automate, ALM, security, and extension traps before practicing.
PL-400 is the developer route for extending Power Platform beyond configuration. Keep the exam lens on Dataverse, plugins, custom connectors, APIs, Power Apps, Power Automate, ALM, security, and supported extension patterns.
Use this with practice. Review the Power Platform developer checkpoints, then return to the PL-400 page for sample questions and update tracking.
| Field | Detail |
|---|---|
| Issuer | Microsoft |
| Certification lane | Power Platform Developer |
| Exam code | PL-400 |
| Main scope | Dataverse customization, plugins, connectors, APIs, Power Apps, Power Automate, security, ALM, and development lifecycle |
| IT Mastery status | Sample questions available |
| Area | What to know | Common trap |
|---|---|---|
| Dataverse | Tables, columns, relationships, security, business rules, and events | Writing code for behavior that configuration already supports |
| Plugins and code | Plugin pipeline, triggers, registration, error handling, and performance | Adding synchronous plugins without considering user impact |
| Connectors and APIs | Custom connectors, authentication, schemas, actions, and failures | Treating API integration as only endpoint wiring |
| App and automation extension | Canvas apps, model-driven apps, Power Automate, and component reuse | Building isolated assets without lifecycle planning |
| ALM and governance | Solutions, environments, source control, deployment, monitoring, and DLP | Shipping unmanaged changes manually |
| Distinction | How to decide |
|---|---|
| Plugin vs Power Automate | Plugins handle Dataverse event logic; flows orchestrate business automation. |
| Custom connector vs standard connector | Custom connectors wrap APIs not covered by standard connectors. |
| Managed vs unmanaged solution | Managed is for deployment; unmanaged is for development. |
| Canvas app vs model-driven app | Canvas apps optimize custom UX; model-driven apps follow Dataverse data model. |
| Security role vs DLP policy | Roles control app/data access; DLP controls connector use. |
When you miss PL-400 questions, identify whether the scenario is about Dataverse, code, connector, app, automation, security, or ALM. Strong answers extend the platform without bypassing governance or upgradeability.
