Integrating Azure Apps with Dataverse via Web API

PL-400 By islever Editorial Last updated

Perform operations by using platform APIs

Short answer

C Use the Dataverse Web API to programmatically create or update records from the external Azure application.

Question

You are building a custom application in Azure to process resumes for the HR department.
The app will monitor submissions of resumes and parse the resumes.
You need to parse the resumes and save contact and skills information into the Common Data Service.
Which mechanism should you use?
  1. Power Automate
  2. Common Data Service plug-in
  3. Web API Correct Answer
  4. Custom workflow activity

Key Takeaways

The key to this question is distinguishing between Power Platform-native tools and external integration points; when a 'custom application in Azure' is specified, it implies using platform APIs rather than flow-based automation.

This question addresses how external Azure applications should interact with the Common Data Service (Dataverse). The correct mechanism is the Web API, which allows direct programmatic data manipulation from custom code.

Common mistake: Many learners select Power Automate because it is the easiest way to move data into Dataverse. However, Power Automate is a low-code tool within the Power Platform ecosystem, whereas the scenario describes a custom Azure app that should use direct API calls for efficiency and control.

Expert Analysis

Why the Answer Is Correct

The scenario specifies a "custom application in Azure" that needs to save data to the Common Data Service (now known as Dataverse). For external, non-Power Platform applications, the official and most efficient method to create or update records is via the Web API (Option C). The Web API provides a RESTful interface that supports CRUD operations, relationships, and batch processing, making it ideal for custom integrations.

Why the Other Options Are Wrong

Power Automate (Option A) is primarily designed for business users to create automated workflows without code. While it can connect to Azure services, it is not the primary mechanism for a custom-coded Azure application to perform data writes; doing so would add unnecessary latency and complexity compared to a direct API call. Common Data Service plug-in (Option B) executes server-side code within the Dataverse environment itself, triggered by specific events; it cannot be called directly from an external Azure app. Custom workflow activity (Option D) is a legacy concept largely superseded by plugins and cloud flows, and like plugins, it runs inside the Power Platform context, not externally.

Community Comment Notes

Community consensus strongly favors Option C. As user c801578 noted, "The scenario says your custom Azure app already monitors uploads and parses resumes... The most direct, first-class way for an external app to write to Dataverse is the Web API." User MuhammadSaadFahim reinforced this by stating, "Azure app can do using by calling Dataverse Web API." Users who chose Power Automate often missed the distinction that the application is already built in Azure, implying a code-first approach rather than a low-code one.

Exam Strategy

When you see "Custom Application" or "External App" in the options, look for "Web API" or "Platform APIs" as the answer. Reserve Power Automate/Cloud Flows for scenarios involving business process automation, approvals, or cross-service orchestration where coding is not the primary requirement.

Frequently Asked Questions

Why not Power Automate for saving resume data?

Power Automate is a low-code tool for business workflows. Since the scenario involves a 'custom application in Azure,' it implies a code-based solution where direct Web API calls are more efficient and appropriate.

Can I use Plug-ins from an Azure app?

No. Plug-ins run server-side within the Dataverse environment and are triggered by internal events. They cannot be invoked directly by an external Azure application.

    I think is A because you need to save on dataverse.
  2. NyarukouSAMA 👍 5 Answered A
    Both A and C are suitable in this situation, but Microsoft recommends using PowerAutomate flow wherever possible. So, I believe the answer should be A.
  3. Sauradj 👍 3
    Why not web api, which can be called from custom application directly to create a record in Dataverse?
  4. c801578 👍 2 Answered C
    Answer: C - Dataverse Web API Why: The scenario says your custom Azure app already monitors uploads and parses resumes. The remaining task is to save contacts/skills to Dataverse. The most direct, first-class way for an external app to write to Dataverse is the Web API (supports create/update, relationships, and batch/transactional writes). Power Automate (A) could also do it, but it adds an extra hop you do not need since your app is already doing the parsing/orchestration. Plug-in (B) and custom workflow activity (D) run inside Dataverse on data events; they are not the right ingress mechanism for an external Azure app pushing data in.

    I think is A. With Pwer Automate you can extract the ressume information and save it in dataverse. With Web API you only can write in dataverse but not extract/process/parse the resume

    C. Web API (Bcz Azure app is doing all process, only the action left is to save contact and skills in dataverse which azure app can do using by calling Dataverse Web API)
  2. andresleonz 👍 2
    Guys it should be "C". Whatever third-party application outside from Power Platform or Dynamics 365
  3. 5f14337 👍 1 Answered A
    Why Power Automate is the best choice: Power Automate is ideal for integrating external apps or services with Dataverse. You can: Trigger a flow when a resume is uploaded (e.g., from Azure Blob Storage, an HTTP call, or an Azure Function). Use connectors or HTTP actions to parse the resume (e.g., using Azure AI Form Recognizer or a custom API). Insert parsed data (contacts, skills) directly into Dataverse tables using native connectors. Fully supports low-code automation, integrates easily with Azure, and is highly maintainable.

    The Azure application should call the Dataverse Web API to create or update records such as: Contacts Skills Parsed resume details Why this is the best fit: The Web API is designed for external applications. Fully supports create, update, batch operations. Highly scalable and secure using Azure AD authentication. Perfect for custom Azure services integrating with Dataverse.
  5. christiangonzalezcatalan 👍 1 Answered C
    I think C is the best answer. They don't talk about the specific tecnology in azure, so, if you want to use power automate, i think it could be possible if you use http trigger and call the power automate from the application. But in this way you need a power automate premium license and power automate doesn't simplified the work. With option C you dont need extra license.

    Using a Web API allows you to build a custom solution that can efficiently parse resumes and handle the specific business logic required for saving data into Dataverse. This approach provides the flexibility needed for the scenario described, allowing the application to monitor submissions, perform complex parsing, and then store the processed data into Dataverse.
  7. fernitudelad 👍 1
    It is saying that "you are building the App" and what mechanism to use. So API is not right, the only mechanism to parse the info and so on is PA. A is correct then
  8. danh_1307 👍 1 Answered C
    Answer C is correct. Answer A is actually possible in this case, but the keywords are "custom application in Azure", which makes it easier to use Web API from here
  9. andresleonz 👍 1
    Sorry, butter finger... External applications should use Dataverse Web API to perform operations in Dataverse, instead of using Power Automate or Middleware.
  10. Tiguer99 👍 1 Answered C
    The Web API allows external applications to communicate directly with Dataverse through secure and supported CRUD operations.
  11. mmamfgm 👍 1
    But the question says, your azure app will extract the resume information and it only asks how to save it in the dataverse
  12. 5f14337 👍 1 Answered C
    Use the Dataverse Web API — it’s the standard, secure, and scalable option for external applications.
  13. WDodd04 👍 1 Answered C
    Agree that the Web API is the most direct method.
  14. Grissinninni 👍 1 Answered A
    Power Automate can handle all the requirement

    A - Power Automate can do the job
