Why exporting and importing a custom connector with Postman fails deployment

PL-400 By islever Editorial Last updated

Create custom connectors

Short answer

B Postman is an API testing tool and cannot deploy a custom connector into a Power Platform production environment, so the solution does not meet the goal.

Question

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than once correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. A company develops a new custom connector for a Microsoft Entra ID-protected Azure Function that was created as a single tenant app. The custom connector must be moved to a production environment. The connector must be visible and accessible only to users in the tenant. You need to deploy the custom connector. Solution: Use Postman to export the custom connector. Then use Postman to import the connector into the production environment. Does the solution meet the goal?
  1. Yes
  2. No Correct Answer

Key Takeaways

Postman is an API client used to test HTTP requests; it has no mechanism to create or deploy a Power Platform custom connector into an environment. Deployment is done through solutions in the maker portal / Power Platform.

The connector must be deployed to the tenant's production environment. The proposed solution uses Postman to export and import the connector. Postman is for testing APIs, not for deploying Power Platform components into environments, so it does not meet the goal.

Common mistake: Mistaking a Postman collection export for a deployment artifact. A Postman collection documents/exports the API definition for testing only; it does not install a connector into a Power Platform environment.

Expert Analysis

Why the Answer Is Correct

Postman is an API development and testing tool. While you can use it to exercise a connector's underlying API, it cannot create or deploy a custom connector object into a Power Platform environment. The supported deployment path is solution export/import; Postman plays no role in environment deployment.

Why the Other Options Are Wrong

The alternative A (Yes) is incorrect because Postman has no environment-deployment capability for connectors. The correct series variant is solution-based export/import.

rrustick (likes=1) states that using Postman to export/import does not meet the goal of deploying to production. loftuscheek (likes=1) describes the correct managed-solution approach as the right method, implying Postman is not.

    You could import the custom connector as a postman collection right?

    Correct Approach: Managed Solution Packaging: Add the custom connector to a managed solution, export the managed solution, and then import it into the production environment. This method meets all the goals of secure, tenant-restricted deployment and aligns with Microsoft’s ALM best practices. False Approaches: Maker Portal Export/Import: Using the maker portal directly to export and import the connector fails to leverage solution management benefits. Postman Export/Import: This manual process bypasses ALM practices and risks misconfiguration. Publishing to AppSource: This approach exposes the connector to a broader audience, contradicting the requirement for tenant-only visibility.

    B. No Explanation: Using Postman to export and import the custom connector does not meet the goal of deploying the connector to a production environment and ensuring it is visible and accessible only to users in the tenant. Postman is an API client tool used for testing and debugging APIs, but it does not provide the necessary functionality to manage custom connectors within the Microsoft Power Platform or Azure environment.
