Cloud Events Storage – Help

Cloud Events Storage is a Business Central extension by Origo that exposes the standard BC external file storage connectors (Azure Blob Storage, Azure File Share, and SharePoint) as Cloud Events message types. External systems gain direct read/write access to cloud storage from Business Central through the Cloud Events API.

The extension adds file, directory, and chunked upload operations as message types to the Cloud Events framework. Each operation is addressed by a storageCode that maps to a configured storage connection.
