Authorize Dynamics 365 F&O

This guide explains how to connect your Dynamics 365 Finance & Operations environment to Stacksync.

1. Find your Microsoft Dynamics Environment URL

Your environment URL is the base address of your D365 F&O instance. To find it, copy the URL from your browser when you are in the application.

Examples:

• Production: https://yourorg.operations.dynamics.com

• Sandbox: https://yourorg.sandbox.operations.dynamics.com

2. Select Dynamics 365 Finance

In Stacksync:

1. Click Create Sync

2. Choose Dynamics 365 Finance & Operations

   

This opens the authorization flow.

4. Sign In with Microsoft

2. Continue to the permissions screen

This authenticates you as a valid D365 user.

5. Grant Stacksync Access

Microsoft will ask you to approve the Stacksync app.

Click Accept to authorize:

• Permission to read ERP data

• Permission to interact with OData entities

If you see this message:

“Need admin approval for this app.”

Ask your admin to:

• Open the Microsoft identity / directory admin portal and go to the enterprise applications / app registrations area.

• Locate the Stacksync application or the corresponding app registration.

• Review and grant the requested API permissions (for example, access to Dynamics 365 F&O APIs).

Once an admin has granted consent, the “Need admin approval” screen will no longer appear when you authorize Stacksync. You can then restart the authorization from step 2, and the flow will complete successfully, allowing Stacksync to connect to your Microsoft account and start syncing data.
