AB-620 validates enterprise Copilot Studio agent engineering with deep technical integrations, while AB-410 validates building AI-first Power Platform applications where apps, flows, and agents work together. As of publication, AB-620 has already reached general availability while AB-410’s launch has slipped past its original July 2026 target.
The direct answer: Choose AB-620 if you are a professional developer or AI engineer building complex, enterprise-grade Copilot Studio agents with system integrations, multi-agent orchestration, and protocols like MCP and A2A. Choose AB-410 if you are a Power Platform functional consultant or app maker whose work spans Power Apps, Power Automate, Power Pages, and Copilot Studio together, and who previously would have targeted PL-200. Both cost $165, and both require no formal prerequisite, but AB-620 is technical and agent-specific, while AB-410 is broader across the full Power Platform stack. Full official details for each live on Microsoft Learn’s AI Agent Builder Associate certification page and the AB-410 certification page.
AB-620 vs AB-410 at a Glance
| Detail | AB-620 | AB-410 |
| Full name | AI Agent Builder Associate | Intelligent Applications Builder Associate |
| Exam title | Designing and Building Integrated AI Agent Solutions in Copilot Studio | Building AI-First Power Platform Applications |
| Cost | $165 | $165 |
| Duration | 120 minutes | Not yet finalized at publication |
| Passing score | 700 out of 1000 | 700 out of 1000 |
| Beta launched | April 21, 2026 | April 2026 |
| General availability | June 2026, on schedule | Originally targeted July 2026, delayed, may land August 2026 |
| Replaces | No retiring predecessor, brand new | PL-200, retiring August 31, 2026 |
| Focus | Enterprise agent engineering, technical integrations | Full Power Platform stack, apps plus agents together |
Important: AB-410’s general availability date has moved. Microsoft originally targeted June 2026, then pushed to July 2026, and as of early August 2026 candidates were still asking Microsoft’s own Q&A forum for an updated timeline. If you are reading a guide that confidently states AB-410 is generally available, verify that against Microsoft Learn directly before trusting it, since the rollout has not gone entirely to plan.
What AB-620 Actually Tests
AB-620 is the most technical certification in Microsoft’s entire AB series. It validates your ability to design, build, integrate, and manage enterprise-grade AI agents using Copilot Studio, Azure AI, and enterprise platforms, well beyond configuring a simple chatbot.
| Area | What You Do |
| Agent design in Copilot Studio | Topic configuration, conversation flow, generative orchestration |
| Multi-agent collaboration | Coordinating multiple agents working together on complex tasks |
| Enterprise system integration | Connecting agents to systems like SAP, ServiceNow, and other enterprise platforms |
| Protocols | MCP (Model Context Protocol) and A2A (Agent-to-Agent) implementation |
| Security and monitoring | Governance, access control, and telemetry for production agent deployments |
Key point: AB-620 sits far beyond AB-900, the foundational Copilot administration exam. AB-900 asks whether you can govern and license Copilot at an organizational level. AB-620 asks whether you can architect and build the agents themselves at a level enterprise integration teams would actually deploy to production.
What AB-410 Actually Tests
AB-410 is Power Platform’s answer to the AI-first era, and it is the official successor to PL-200, which retires August 31, 2026.
| Area | What You Do |
| Power Apps with AI | Building intelligent canvas and model-driven apps with embedded AI capabilities |
| Power Automate integration | Combining flows with agent-driven automation |
| Power Pages | AI-first external-facing application design |
| Copilot Studio, foundational level | Basic agent building as one part of a broader application, not the deep specialization AB-620 requires |
| Dataverse and data modeling | The data layer underneath AI-first Power Platform solutions |
Note: AB-410 is not simply PL-200 with an AI chapter added. One beta candidate who took the exam described it as testing whether you can bring AI into solutions you already know how to build, rather than treating AI as a separate topic to memorize. If your PL-200 preparation is otherwise solid, layering AI-first thinking onto that existing knowledge covers most of the gap.
The Real Difference: Depth vs Breadth
The direct comparison: AB-620 goes deep into one thing, enterprise agent engineering, with genuine technical complexity around integrations, orchestration, and protocols. AB-410 goes broad across the whole Power Platform stack, treating agents as one capability among several rather than the central focus. Neither is harder in an absolute sense. They test different things for different roles.
| If Your Work Involves | Choose |
| Building one specific, complex Copilot Studio agent for enterprise system integration | AB-620 |
| Building a full application where an agent is one component among several | AB-410 |
| Connecting agents to SAP, ServiceNow, or other enterprise backends | AB-620 |
| Power Apps, Power Automate, and Power Pages as your primary daily tools | AB-410 |
| A background in software engineering moving into AI agent specialization | AB-620 |
| A background as a Power Platform functional consultant or app maker | AB-410 |
| Multi-agent orchestration and protocol-level integration work | AB-620 |
| General business application building with AI features layered in | AB-410 |
Who Should Take AB-620, and Who Should Take AB-410
Professional developers and AI engineers already comfortable with code-level integration work. If you regularly work with APIs, enterprise system connectors, and are being asked to build agents that do more than answer simple questions, AB-620 validates exactly that skill set and nothing else gets you there faster.
Architects planning a path toward AB-100. Both AB-410 and AB-620 qualify as the associate-level prerequisite for AB-100, Microsoft’s expert-level agentic AI architecture certification, but AB-620 builds the deeper technical foundation AB-100’s design domain draws on most heavily.
Power Platform functional consultants and business analysts whose PL-200 was about to expire. AB-410 is the direct, intended replacement, and Microsoft built it specifically so existing Power Platform knowledge transfers rather than requiring a fresh start.
Makers who build agents but only against common data sources like SharePoint and OneDrive, without needing enterprise system integration, are actually better served by AB-610, Copilot Studio Agent Maker, once that certification’s beta date is confirmed. That credential fills the space between AB-410 and AB-620, and forcing yourself into AB-620’s enterprise integration content when your actual work never touches SAP or ServiceNow-level systems wastes study time on content you will not use.
Cost and Total Investment
Required Costs
| Item | AB-620 | AB-410 |
| Exam fee | $165 | $165 |
| Retake fee | $165, full price again | $165, full price again |
Strongly Recommended Supplementary Costs
| Item | Amount | Notes |
| Microsoft Learn self-paced training | $0 | Official, free, and the primary preparation path for both exams |
| Third-party practice question sets | $30 to $80 | Useful once official practice assessments become available, typically within 8 weeks of general availability |
| Hands-on Copilot Studio and Power Platform trial environment | $0 | Free developer environments are sufficient for most exam preparation |
Possible Additional Costs
| Item | Amount | Notes |
| Retake after a failed attempt | $165 | 24-hour wait after first failure, 14 days between subsequent attempts, maximum 5 attempts per 12-month period |
| Instructor-led course, optional | $500 to $1,500 | Not required, most candidates succeed with free Microsoft Learn content alone |
The honest total: Most candidates preparing for either exam spend $165 to $250 all in, since both are built around Microsoft’s own free training content and the exam fee itself is identical. The real cost difference between the two credentials is time, not money, given AB-620’s narrower but deeper technical scope.
AB-620 and AB-410 Cost Outside the United States
| Region | Exam Fee (approximate) |
| United States | $165 USD |
| United Kingdom | £135 |
| India | ₹13,750 |
| European Union | €155 |
| Canada | $225 CAD |
| Australia | $250 AUD |
Note: Microsoft adjusts certification pricing by country rather than applying a flat currency conversion. Confirm your exact regional price on the Pearson VUE scheduling page before registering, since both AB-620 and AB-410 are new enough that regional pricing may still be settling in some markets.
Can You Take Both?
Yes, and for candidates working across both technical agent engineering and broader Power Platform development, taking both makes genuine sense rather than being redundant. There is no prerequisite requirement linking them, and Microsoft’s own suggested Power Platform track explicitly sequences AB-410 first for application building, then AB-620 for those who want to specialize further into enterprise agent engineering, then AB-100 for expert-level architecture. For the complete progression across the whole AB series, including the 5 additional 2026 credentials beyond these two, see our Microsoft AB Series Certifications guide.
What Happened to PL-200
If you were preparing for PL-200, the Power Platform Functional Consultant Associate exam, it retires August 31, 2026, and AB-410 is its official, Microsoft-designated replacement. Your existing PL-200 knowledge transfers directly, since the underlying platform is the same. What changes is the framing: PL-200 asked whether you could configure the platform, while AB-410 asks whether you can build AI-first solutions where apps, agents, automation, and models work together. For the complete transition guide covering exactly what carries over and what is genuinely new, see our PL-200 vs AB-410 guide.
Common Mistakes When Choosing Between AB-620 and AB-410
Assuming AB-620 is simply a harder version of AB-410. It is not a difficulty tier, it is a different focus entirely. A candidate could reasonably find AB-620 easier than AB-410 if their daily work is agent-specific integration rather than broad Power Platform development.
Choosing AB-620 because it sounds more advanced, without actually doing enterprise agent integration work. AB-620’s content assumes real exposure to enterprise system connectors and multi-agent orchestration. Candidates without that exposure often find the gap between AB-410’s breadth and AB-620’s specialization wider than expected.
Assuming AB-410 is generally available today without checking. As of publication, AB-410’s rollout has slipped past its original target. Confirm current status on Microsoft Learn before building a study timeline around a fixed exam date.
Treating these as mutually exclusive when your role genuinely spans both. If you build full Power Platform solutions that also include serious agent engineering work, both credentials accurately represent different parts of your actual job.
Forgetting that PL-200 is still retiring regardless of which AB-series path you choose. If you are mid-preparation for PL-200 and can finish before August 31, 2026, that remains a valid option, but new candidates starting today should plan around AB-410 directly.
Frequently Asked Questions
What is the difference between AB-620 and AB-410?
AB-620 is for enterprise agent developers building complex Copilot Studio agents with system integrations, multi-agent orchestration, and protocols like MCP and A2A. AB-410 is for Power Platform professionals building intelligent applications where apps, flows, pages, and agents work together as one broader solution.
Which is harder, AB-620 or AB-410?
Neither is objectively harder. AB-620 tests deep, narrow technical skill in agent engineering. AB-410 tests broad competency across the full Power Platform stack. Difficulty depends on which one matches your actual working background.
Is AB-410 generally available yet?
Its rollout has been delayed. Microsoft originally targeted June 2026, then pushed to July 2026, and as of early August 2026 the exact general availability date had still not been confirmed publicly. Check Microsoft Learn directly for the current status before scheduling.
Does AB-620 replace a retiring certification?
No. Unlike AB-410, which replaces PL-200, AB-620 is a brand new certification with no predecessor. It fills a gap that did not previously exist in Microsoft’s catalog for enterprise-grade Copilot Studio agent engineering.
Can I take both AB-620 and AB-410?
Yes. There is no prerequisite linking them, and Microsoft’s suggested Power Platform track sequences AB-410 first, then AB-620 for candidates who want to specialize further into enterprise agent engineering.
Do I need PL-200 experience before taking AB-410?
No formal prerequisite exists, but candidates with existing Power Platform or PL-200 background report an easier transition, since AB-410 builds AI-first thinking onto the same underlying platform rather than starting from zero.
How much does AB-620 or AB-410 cost?
Both cost $165 USD for the exam. Retakes cost the full $165 again, with no discount, and a mandatory waiting period between attempts.
Which certification should I take if I want to eventually earn AB-100?
Either qualifies as the associate-level prerequisite for AB-100. AB-620 builds a deeper technical foundation for AB-100’s agentic design domain specifically, while AB-410 provides broader Power Platform context.
What does AB-620 cover that AB-410 does not?
AB-620 covers enterprise system integrations, multi-agent orchestration, and protocol-level work with MCP and A2A, none of which appear in AB-410’s broader application-building scope.
Is there a certification between AB-410 and AB-620 for simpler agent building?
Yes, AB-610, Copilot Studio Agent Maker, is positioned for makers building agents against common data sources like SharePoint and OneDrive, without the enterprise integration complexity AB-620 requires. Its beta date had not been confirmed as of publication.
