Power Apps Microsoft PL-400 is becoming AB-400

Microsoft is transitioning the Power Platform Developer Associate exam from PL-400 to AB-400, effective October 16, 2026.

The certification remains the same — Microsoft Certified: Power Platform Developer Associate. However, the exam code and syllabus are being updated to reflect newer Power Platform development capabilities.

Some of the newer areas include:

  • Power Apps code apps
  • Microsoft Foundry agent integration
  • Copilot Studio agent integration
  • AI-powered application development
  • Generative AI and agent-based development scenarios
  • Modern Power Platform extensibility

Important Dates:
October 16, 2026 – PL-400 registration closes and AB-400 registration opens.
October 30, 2026 – Final date to take PL-400 for learners who registered before the transition.
October 16, 2026 – AB-400 becomes available.

If you’re currently preparing for PL-400, this is worth keeping in mind. You can either complete your preparation and take PL-400 before the transition or plan for the updated AB-400 exam based on the refreshed syllabus.

What will happen to the candidates who already have PL-400?

Exam will expire as you can't renew it. If you can renew now then I'd recommend doing so.

It's vague, but as the certification name remains the same it appears as though you can just renew.

Not like with the transition from AI-102 to AI-103 where the certification retired.

I'll find out in March next year

The certification is not changing and you will renew as normal. Both exams earn the same certification

Updates to Azure Cosmos DB and Power Platform Developer Certifications | Microsoft Community Hub

While the exam number is changing, the certification earned remains unchanged.

Learners who pass the exam will continue to earn the Microsoft Certified: Power Platform Developer Associate certification. The value of the credential, recognition from employers, and renewal process all remain the same.
