Introduction:
After upgrading Business Central to version 17 (Wave2 2020), I found that there was an error telling me that WebService Key is going to be deprecated soon. |
| Web Service Access Key is deprecated. |
Hence, I decided to explore and probably make it easier through this blog.
Pre-requisites:
- Admin Access to Office 365
- Admin Access to Azure
Demonstration:
1. App Registration on Azure Portal:To enable OAuth authentication for any apps in Azure Active Directory, you will need to perform App Registration and set up the permissions and security details.
i.) Register the App: Search for 'App Registration' on the Azure Portal.
 |
| Click on New Registration |
Type in the App Names, Account Types and Redirect URI.
 |
| Registering Application |
ii.) Setup API Permissions:
Go to API Permissions > Add Permissions > Business Central App > Select Delegated Permissions > Select Other Permissions and Financials > Add Permissions Button.
Go to API Permissions > Add Permissions > Business Central App > Select Delegated Permissions > Select Other Permissions and Financials > Add Permissions Button.
 |
| Setup API Permissions |
iii.) Setup Client Secret:
Goto Client Secret > Give a Key Name, Description, and Create New Client Secret.
This Client Secret is the Password for OAuth.
 |
| Creation of Client Secret |
Unless you create the Client Secret, the Client Secret is not generated.
 |
| Client Secret is generated |
The value here is the Client Password
Now, we are all set for OAuth Authentication.
2. Get Token in Postman:
Prior to getting token in Postman, we need to make sure the parameters are ready.
Prior to getting token in Postman, we need to make sure the parameters are ready.
Token-Name: Give the appropriate Token Name
Grant Type: Authorization Code
Callback URL: https://businesscentral.dynamics.com/
Auth URL: https://login.windows.net/<TENANT-ID>/oauth2/authorize?resource=https://api.businesscentral.dynamics.com
Access Token URL: https://login.windows.net/<TENANT-ID>/oauth2/token?resource=https://api.businesscentral.dynamics.com
Client ID: Client ID on the App Registration
Client Secret: Client Secret Value generated recently.
This will generate the Access Token in Postman.
Using this token, now you will be able to get access to Business Central WebService or APIs.
Conclusion:
I wrote this blog because there are a lot of tricky things to follow and get this correct at the first attempt.
The advantage of using such a type of authentication is that irrespective of the user changing credentials.
I hope this helps. 👍
