How to Use Dataverse Web APIs with Postman (Step-by-Step Guide)

Microsoft Dataverse provides powerful REST Web APIs that allow developers and administrators to interact with tables, records, and metadata programmatically. Instead of writing code immediately, we can first test these APIs using Postman, which is the easiest and fastest way to understand how Dataverse works.

In this article, we will learn how to call Dataverse Web APIs using Postman and verify the responses in a simple step-by-step manner.

I will also show you how to quickly configure a Postman environment so you can start testing Dataverse APIs right away.

The best part is — you do not need to create a new Azure AD App Registration (Client ID and Client Secret). By following the steps below, you can use Microsoft’s public client application ID, which works across Dataverse environments for testing purposes.

Prerequisites

Before starting, make sure you have the following:

A Microsoft Dataverse environment (Power Apps / Dynamics 365)
Access to the environment (user account with permissions)
Postman Desktop Application installed on your computer (Windows recommended)

Step 1 — Launch Postman

Open the Postman Desktop Application on your machine.

Step 2 — Create a Collection

In Postman, go to the Collections tab.
Click New → Collection
Name the collection:

Dataverse API GetLoginToken

This collection will store all your Dataverse requests (GET, POST, PATCH, DELETE).

Select Authentication Type Oauth2

Now enter the following details.

Field	Value
Grant Type	Authorization Code
Callback URL	https://oauth.pstmn.io/v1/callback
Auth URL	https://login.microsoftonline.com/YOUR_TENANT_ID/oauth2/v2.0/authorize
Access Token URL	https://login.microsoftonline.com/YOUR_TENANT_ID/oauth2/v2.0/token
Client ID	51f81489-12ee-4a9e-aaae-a2591f45987d
Client Secret	(leave blank)
Scope	https://YOURORG.crm.dynamics.com/.default
Client Authentication	Send as Basic Auth header

Replace:

YOUR_TENANT_ID → Azure Active Directory Tenant ID
YOURORG → your Dataverse environment name

Then click Get New Access Token

A Microsoft sign-in page will open → login → accept permissions.

After token is generated → click Use Token

Now all requests inside the collection are authenticated automatically.Then, click on new access token and proceed, then hit the END api Call

Step 2 — Call Dataverse API (GET Records)

Create a new request inside the collection.

Method: GET

Request URL

https://YOURORG.crm.dynamics.com/api/data/v9.2/accounts

If you want, I can also write the next sections (Environment variables, Access Token generation, OAuth URL, sample GET records request). That part is actually the most important for ranking because people search for “Dataverse API Postman access token”.
