SOAP Web Services

  • 發行項

SOAP web services enable full flexibility for building operation-centric services. They provide industry-standard interoperability and channel and host pluggability.

You can use SOAP to interact with page or codeunit web services in Business Central.

Note

  • Support for SOAP endpoints is deprecated in Business Central and will be removed in an upcoming release. Start to move your solutions to use either ODataV4 or API pages/queries. API pages/queries are recommended.

  • Support for publishing Microsoft UI pages as SOAP web services will be removed in Business Central 2026 release wave 2 (version 29.0). Starting in version 26.0, Microsoft UI pages can't be published as SOAP web services unless the Feature: Disable SOAP web services on Microsoft UI pages key in Feature Management is turned off. Learn more Disable SOAP web services on Microsoft UI pages feature key.

Learn more about the removal timelines in Deprecated Features in the Platform - Clients, Server, and Database.

Note

Instead of exposing UI pages as web service endpoints, use API pages or API queries because they've been optimized for this scenario. For more information, see Writing efficient Web Services
