AB-620 vs AB-410: Which Microsoft AI Builder Certification to Take in 2026

Last updated: August 2026

TL;DR AB-620 (AI Agent Builder Associate) is the developer exam: you build, integrate and harden agents in Copilot Studio using MCP, REST APIs and Microsoft Foundry. AB-410 (Intelligent Applications Builder Associate) is the low-code maker exam: you build Power Platform apps and automation that consume AI. Choose by role, not by sequence.

Two new Microsoft associate certifications sit close enough together to cause genuine confusion, and picking the wrong one first wastes weeks of study time. AB-620 (Microsoft Certified: AI Agent Builder Associate) and AB-410 (Microsoft Certified: Intelligent Applications Builder Associate) are both intermediate-level, both 120 minutes, and both qualify you for the same expert track. Yet they measure very different jobs. This guide explains the real difference, shows a side-by-side comparison, and helps you decide which to sit first based on what you actually do at work.

What is the AB-620 certification?

AB-620 leads to the Microsoft Certified: AI Agent Builder Associate credential, and it is Microsoft's exam for people who build and integrate custom agents at enterprise scale [1]. The official audience profile describes "a professional developer or advanced builder who builds, extends, and integrates custom agents for enterprise-grade solutions," typically working as an IT application developer, consultant, or independent software vendor (ISV) partner [1].

The exam centres on Microsoft Copilot Studio, going deep on agent flows, topics, tools and multi-agent orchestration [3]. Beyond Copilot Studio itself, AB-620 expects you to integrate agents with external systems: Model Context Protocol (MCP) servers, custom connectors, REST APIs, Azure AI Search, the Microsoft Foundry model catalogue, Microsoft Fabric data agents, and multi-agent collaboration through the Agent2Agent (A2A) protocol [3]. In other words, this is an agent-engineering exam, not an app-building one.

One quirk worth flagging: Microsoft's own pages currently carry a small title inconsistency. The certification badge reads "AI Agent Builder Associate," while the study guide's page title drops the word "Agent" and reads "Designing and Building Integrated AI Solutions in Copilot Studio" [1][3]. The credential name is stable; only the underlying exam title wording flips between fields on the same page. It does not change what the exam tests.

What is the AB-410 certification?

AB-410 leads to the Microsoft Certified: Intelligent Applications Builder Associate credential, and it is Microsoft's exam for low-code makers who build AI-enabled applications on Power Platform [2]. The official audience profile is explicit: you are "a professional who builds AI-powered solutions in Microsoft Power Platform by using Microsoft Copilot, natural language prompts, and low-code tools" [2].

The exam centres on the Power Platform stack: Power Apps (canvas and model-driven), Power Automate cloud flows, Power Pages, Dataverse data modelling, and AI Hub for consuming prompts and AI models inside apps and flows [4]. You create apps, data models and flows that connect to agents, AI models and visualisations, then enrich those experiences with Copilot features embedded in the surfaces you build [2].

This corrects a common assumption. AB-410 is sometimes described as the "developer" or "pro-code" exam because it carries a Developer role tag on Microsoft's taxonomy. The audience profile says the opposite: AB-410 centres on natural-language prompts and low-code tools, and lists Power Fx and low-code automation as prerequisites, not a pro-code skillset [2]. On the maker-versus-developer axis, AB-410 is the low-code maker exam and AB-620 is the developer exam.

The real difference: app layer versus agent layer

The cleanest way to separate these two certifications is by which layer of the solution you own. AB-410 candidates build the application that an agent lives inside. AB-620 candidates build and integrate the agent itself.

AB-410 is about the application layer. You are a Power Platform maker assembling apps, data models, forms and automation, then consuming AI and Copilot capabilities through natural language and pre-built AI Hub prompts [2][4]. The heaviest-weighted domain, at 40 to 45 percent, is "Build business application logic and automation," which is classic Power Platform app-builder territory with an AI layer added on top [4].

AB-620 is about the agent layer. You are a developer going deep on Copilot Studio specifically, then extending and hardening agents against external systems through MCP, custom connectors, REST APIs, Azure AI Search, Microsoft Foundry and multi-agent orchestration [3]. The heaviest-weighted domain, again at 40 to 45 percent, is "Integrate and extend agents in Copilot Studio," which is enterprise agent engineering rather than app assembly [3].

The two overlap at exactly one seam, and it is a useful one to understand. AB-410's own skills outline includes "create a Copilot Studio agent from a canvas app," and AB-410 candidates are expected to have "awareness of creating agents with Microsoft Copilot Studio" [4]. So an AB-410 maker knows an agent exists and can spawn a basic one; an AB-620 developer then takes that agent and wires it into the rest of the enterprise. Many Power Platform consultants do both jobs, which is why both credentials can make sense for one person over time.

Shared foundations both exams assume

Before either exam tests its specialist content, both assume the same low-code base layer, and underestimating that base is a common reason candidates struggle. Both AB-620 and AB-410 are built on Microsoft's Power Platform substrate, and both explicitly expect familiarity with Power Fx and Dataverse [1][2].

Both exams also touch the same Copilot Studio seam from opposite sides. AB-410 candidates need awareness of creating agents in Copilot Studio, and AB-620 candidates build and extend those same agents in depth [3][4]. If you have never opened Copilot Studio, that gap will show on either exam, so it is worth some hands-on time regardless of which you choose.

The logistics are identical too, which simplifies planning. Both run for 120 minutes, both require a scaled score of 700 to pass, both are proctored through Pearson VUE with the possibility of interactive components, and neither has a practice assessment available yet [1][2][3][4]. Microsoft also warns on both certification pages to register with a personal Microsoft account rather than a work or school account, so your exam records are not lost if you leave your current organisation [1][2].

Where the two diverge on logistics is language. AB-620 is offered in 13 languages, including English, French, German, Japanese and Spanish, while AB-410 is currently offered in English only [1][2]. If English is not your first language, that difference alone may steer your choice.

AB-620 vs AB-410: side-by-side comparison

The table below summarises the verified differences. Where Microsoft does not publish a figure, the table says so rather than guessing.

Skills domains and weightings

The two exams publish very different skill breakdowns, and the weightings tell you where to focus your study time.

AB-620 skills at a glance [3]:

• Plan and configure agent solutions: 30 to 35 percent
• Integrate and extend agents in Copilot Studio: 40 to 45 percent
• Test and manage agents: 20 to 25 percent

AB-410 skills at a glance [4]:

• Create a foundation for intelligent applications: 25 to 30 percent
• Create intelligent applications: 25 to 30 percent
• Build business application logic and automation: 40 to 45 percent

AB-620 skills outline breakdown

AB-620 rewards depth in integration, which is where nearly half the marks sit [3]. The exam expects you to plan enterprise-system integration, define an identity strategy, choose channels and deployment paths, and apply a responsible AI strategy across the agent's lifecycle [3].

The largest domain, integrating and extending agents, covers creating and monitoring agent flows, configuring topics, adaptive cards and generative answers, and connecting agents to enterprise knowledge sources including Azure AI Search [3]. It also covers configuring MCP tools, custom connectors and REST APIs, plus multi-agent collaboration through Microsoft Foundry agent integration, Fabric data agents and the A2A protocol [3].

The final domain, testing and managing agents, covers building test sets, running evaluation methods, and application lifecycle management for agents through solutions, environment variables and Power Platform Pipelines [3]. If you cannot comfortably reason about REST integration and multi-agent orchestration, AB-620 will feel hard.

AB-410 skills outline breakdown

AB-410 rewards breadth across the Power Platform maker toolkit, with the heaviest weighting on application logic and automation [4]. You start by designing Power Platform solutions with AI-enabled tools and building Dataverse data models, which forms the foundational domain [4].

The middle domain, creating intelligent applications, covers building model-driven and canvas apps, generating pages from natural language, and creating a Copilot Studio agent from a canvas app [4]. This is the seam where AB-410 touches the agent world, but it stops at creation rather than deep integration.

The largest domain, business application logic and automation, covers creating cloud flows, building prompts and models in AI Hub, and configuring business rules, process flows and calculated columns [4]. The centre of gravity here is low-code automation enriched with AI, not agent engineering.

How to choose which exam to sit first

Neither exam is a prerequisite for the other, so the decision is about your role and your day-to-day work rather than a fixed order [5]. Use the guidance below.

If you are a Power Platform maker or app builder, sit AB-410 first. Your daily work is canvas and model-driven apps, Dataverse models and Power Automate flows, and AB-410 certifies exactly that with an AI layer on top [2][4]. It validates the skills you already use and gives you a clean on-ramp to the agent world through the "create a Copilot Studio agent from a canvas app" seam [4].

If you are a developer, integration engineer, consultant or ISV partner, sit AB-620 first. If you spend your time wiring systems together with REST APIs, custom connectors and now MCP, AB-620 maps to your work directly and goes far deeper on Copilot Studio and Microsoft Foundry [1][3]. The 13-language availability also makes it easier to schedule in non-English markets [1].

If you are a Power Platform consultant who does both, start with the exam closest to your current billable work, then add the other within a few months. Consultants frequently build the app and the agent, so both credentials strengthen your profile, and both count towards the same expert certification [5]. A practical order is AB-410 to formalise your app-building foundation, then AB-620 to prove enterprise agent integration.

One thing to note on scheduling: Microsoft does not publish a fixed price for either exam, stating only that the price is "based on the country or region in which the exam is proctored" [1][2]. Check the exact fee in the Pearson VUE booking flow for your region before you commit. There is also no practice assessment for either exam yet, so plan to build hands-on lab time into your preparation [1][2].

How both exams feed into AB-100

Both AB-620 and AB-410 are qualifying associate prerequisites for the expert-level AB-100 (Agentic AI Business Solutions Architect) certification [5]. Microsoft's AB-100 exam page lists both among the associate certifications that can be used towards the expert credential, alongside options such as AI-103, AI-300, PL-200 and several Dynamics 365 associate certs [5].

This confirms they are parallel routes, not a required sequence. Microsoft presents AB-620 and AB-410 as alternative associate entry points into the same architect track, so you can reach AB-100 through either one [5]. Third-party claims that AB-410 must come before AB-620 are not corroborated by any official Microsoft page; treat that ordering as opinion, not a rule.

If your longer-term goal is the architect credential, the practical takeaway is reassuring: whichever of the two you sit first still counts, so you can lead with the exam that matches your current role and add the second later.

How to prepare for AB-620 or AB-410

Because neither exam has a practice assessment yet, hands-on lab time is the single most valuable preparation you can do [1][2]. Read the exam's published skills outline first, then build against it feature by feature rather than relying only on reading. Microsoft revises these outlines periodically, so always work from the live study guide rather than a cached copy [3][4].

For AB-620, concentrate your effort on the integration domain, since it carries 40 to 45 percent of the marks [3]. Practise wiring an agent in Copilot Studio to real knowledge sources, configuring MCP tools and custom connectors, calling REST APIs, and connecting to the Microsoft Foundry model catalogue and Fabric data agents [3]. Rehearse multi-agent scenarios using the A2A protocol, and make sure you can reason about identity strategy and responsible AI, not just the happy path [3].

For AB-410, spread your practice across the whole Power Platform toolkit, since the exam tests breadth [4]. Build canvas and model-driven apps, model data in Dataverse, author cloud flows in Power Automate, and create prompts and models in AI Hub [4]. Practise generating pages from natural language and creating a Copilot Studio agent from a canvas app, since that is the exam's bridge into the agent world [4].

For both, treat the published skills outline as your checklist and confirm the exact regional fee in the Pearson VUE booking flow before you book, since Microsoft does not publish a fixed price [1][2]. Avoid any resource advertising "exam dumps" or leaked questions; they are against Microsoft's certification agreement and are no substitute for building real solutions.

An honest note on difficulty

Neither exam is a beginner certification, and neither is a quick win. Both are Associate, Intermediate-level exams, and both assume real hands-on familiarity with the Power Platform substrate, including Power Fx and Dataverse, before you even reach their specialist content [1][2].

AB-620 is demanding on the integration side. Nearly half the marks sit in "integrate and extend agents," which assumes intermediate generative-AI knowledge covering RAG, MCP and the A2A protocol, plus comfort with REST APIs and identity strategy [3]. If those are unfamiliar, budget serious study and lab time.

AB-410 is broad rather than deep, and the challenge is coverage. You are tested across app building, data modelling, automation and AI Hub in a single 120-minute sitting, so gaps in any Power Platform pillar will cost you [4]. Anyone promising a guaranteed pass or selling "leaked questions" is worth avoiding; the reliable path is hands-on practice against the published skills outline.

Frequently Asked Questions

What is the difference between AB-620 and AB-410?

AB-620 is Microsoft's developer exam for building and integrating agents in Copilot Studio using MCP, REST APIs and Microsoft Foundry. AB-410 is the low-code maker exam for building Power Platform apps and automation that consume AI. Put simply, AB-410 builds the app; AB-620 builds the agent that lives inside it.

Do I need to pass AB-410 before I can take AB-620?

No. Neither exam is a prerequisite for the other. Microsoft's AB-100 page lists both AB-620 and AB-410 as parallel, independent associate certifications, so you can sit them in either order or take just one. Choose based on your role, not on any assumed sequence, since neither gates the other.

Is AB-620 a developer exam or a maker exam?

AB-620 is the developer exam. Its official audience is a professional developer, consultant or ISV partner who builds, extends and integrates custom agents for enterprise solutions. It goes deep on Copilot Studio, MCP, REST APIs and Microsoft Foundry. AB-410, by contrast, is the low-code maker exam focused on Power Platform apps.

Which exam should a Power Platform consultant take first?

Start with the exam closest to your current billable work. If you mainly build apps, flows and Dataverse models, sit AB-410 first. If you mainly integrate systems with APIs and Copilot Studio, sit AB-620 first. Many consultants eventually take both, since each credential covers a different layer of the same solution.

Do both AB-410 and AB-620 count towards the AB-100 certification?

Yes. Both AB-620 and AB-410 are listed on Microsoft's AB-100 exam page as qualifying associate prerequisites for the expert-level Agentic AI Business Solutions Architect credential. They are alternative routes into the same architect track, so whichever you pass first still counts towards AB-100. You do not need both to qualify.

Ready to choose your path?

The decision comes down to one question: do you build the app, or do you build the agent inside it? Match the exam to your role, sit it first, and add the second later if your work spans both layers. Both routes lead to the same expert architect track, so there is no wrong first step.
