Ultimate Guide to Microsoft Dynamics 365 Business Central API


Save time and money by using Business Central API integration to seamlessly add Tipalti AP automation software.

ERP systems, including Microsoft Business Central, use API (application program interface) connections or a different type of connector to integrate third-party software seamlessly and share data between the software as a unified solution. Business Central is an ERP system for midsize and small businesses.

This article explores the specifics of the Microsoft Dynamics 365 Business Central API and covers ERP integrations for Tipalti AP automation software with Business Central. Microsoft Dynamics 365 Business Central was formerly branded as NAV.

Does Business Central Have an API?

Yes. Business Central has a point-to-point API connector (currently API v2.0) for integration with external software that uses Business Central REST API technology to interchange data. Microsoft refers to API connections with its ERP software and third-party software or services as Connect apps. REST stands for REpresentational State Transfer.

With Business Central API integration, your business can use the ERP and add-on third-party software applications as a unified system.

Microsoft provides Business Central API documentation (docs) to help users understand how to make API connections. GitHub also includes documentation for Microsoft Dynamics 365 Business Central AP version 2.0.

When reading Microsoft Business Central API documentation, you’ll find more specific documentation steps for Business Central API endpoints and other topics covering Dynamics 365 Business Central on-premises and online version integration. Microsoft also provides guides for Enabling the APIs for Business Central and Troubleshooting REST API/OData calls. Business Central has an API Setup page to Integrate APIs.

You can use either Business Central built-in APIs or customer APIs. According to Microsoft:

“Business Central comes with an extensive list of built-in APIs that requires no code and minimal setup to use. When using the built-in APIs, please choose the highest API version available. You can also develop your own custom APIs using the AL object types API pages and API queries.”

As part of its documentation, Microsoft offers tips for working with APIs. Microsoft defines API page type (PageType = API) as follows:

“Pages of the type API are used to create versioned, webhook-supported, OData v4 enabled REST web services. This type of page can’t be displayed in the user interface, but is intended for building reliable integration services.”

What Type of API Does Business Central Use?

Business Central uses a REST API for third-party software integration. Businesses can develop a Connect app using any coding language capable of calling REST APIs for their Business Central API.

How to Use Business Central API

Microsoft documentation for Business Central API version 2.0 includes instructions for how to develop Connect apps to use Microsoft Dynamics 365 Business Central and third-party software or services in a unified system with a point-to-point connection. The Connect app uses standard REST API to interchange data. For API data exchange, JSON is the preferred format.

Any integration uses a web services client for making REST API calls through the REST API interface of Microsoft Dynamics 365 Business Central. The Business Central Environment includes Custom APIs and Built-in APIs for Data, Environment administration, Tenant administration, and Tenant migration. 

Microsoft Business Central provides steps in its documentation for developing a Connect app to set up a trial tenant, then connect and authenticate. Put the environment name in the path to construct the URL for the environment by using the Business Central environments list

As part of the Business Central Connect app development process, sign in to the Microsoft Azure portal to register Dynamics 365 Business Central as an app. Set up Microsoft Entra ID-based authentication, following the Microsoft instructions. Use OAuth 2 for web services basic authentication (For on-premises, Microsoft provides details for basic authentication with the use of access keys.)

After setting up the username and password, connect and authenticate. The connect and authenticate process can be from your code or API explorers, including Insomnia, Bruno, or Insomnium.
