Connect to Business central Web Service from Power Automate

(0) ShareShare
ReportReport
Posted on by 12

We have some old Power Automate flows which connected to an on-premise 2018 NAV. We are now beginning an upgrade to Business Central SaaS. 

We make use of many Web Services (Basic Authentication) for our integrations and as a result we use a lot of HTTP connectors in cloud flows to read and create data in nav. 

I'm aware the new and suggested method is to use API pages and the Business Central connectors, but this would require a lot of work to recreate the flows, which I would like to avoid. 

I have set up and App Registration which works in postman just fine, but how do I translate this to a HTTP connector in Power Automate. 

I have tried setting the authentication type to "Active Directory Oauth" and providing the Tenant, Client ID and Client Secret, but I get invalid credentials error. 

Do I need an initial HTTP connector to retrieve an access token before each existing HTTP request? How would this look?
