Create Web service In Business Central

 Web service in Business Central

In Business Central, web services are used to expose the functionality of the system to external applications over the internet. This allows other applications to access and manipulate data in Business Central, and to perform tasks such as creating new customers, posting sales invoices, and more.

There are two types of web services in Business Central: SOAP and OData.

SOAP (Simple Object Access Protocol) web services are based on the standard web services protocol and are primarily used for integration with older systems that do not support OData.

OData (Open Data Protocol) web services are based on the OData standard, which is a more modern protocol for accessing and manipulating data over the web. OData web services provide a more efficient and flexible way to access data in Business Central, and are the recommended option for integration with newer systems.

To create and expose a web service in Business Central, you will need to use the development environment to create a new web service and define the operations that it will perform. Once the web service is created, it can be published to a web server, and the URLs for the web service can be shared with external applications.

In addition to creating custom web services, you can also use the built-in web services that come with Business Central such as the OData v4 web service, which provides access to data in Business Central through a standard OData endpoint.

It’s important to note that web services can be a security risk if not properly secured, so you should make sure that you follow best practices for securing web services, such as using secure connections and authentication.

There are three ways to publish Web service as Page, Codeunit, Query , To Publish them Object ID used as for Codeunit- 5, Page – 8, Query 9.

Codeunit and Page are valid types for SOAP web services. Page and Query are valid types for OData web services.
