Every time I start a new Business Central API project, I end up setting up the same things again. Token request, authentication, variables, and a few common calls, before I even touch the endpoint I actually need to test.
So I built a Postman collection that has all of that ready to go.
What It Includes
- Client credentials token request built in. Run it once and the token saves to a collection variable automatically.
- Every BC API v2.0 endpoint from the official Microsoft documentation, organized into folders: customers, vendors, companies, journals, dimensions, fixed assets, sales documents, purchase documents, and more.
- Self contained. No separate environment file to import.
- List Companies request included so you can grab a company ID right away, since most BC endpoints are company specific.
Getting Started
You will need a Business Central environment, an Entra ID app registration, API permissions, and your tenant ID, client ID, and client secret. Import the collection, open the Variables tab, and enter your values.
If you are not familiar with creating an app registration in Entra ID, there is a separate guide covering that step by step.
