JSON

JSON is the default format for queue- and API-based integrations. The framework includes DEVIntegJObject for parsing and DEVIntegJsonWriter for producing JSON in X++, typically together with contract classes describing the document (for example DEVIntegTutorialSOHeaderContract / DEVIntegTutorialSOHeaderLinesContract).

Sample: sales orders from Azure Service Bus

Sales orders arrive as JSON messages in a Service Bus queue; each message is parsed into staging and a sales order is created. Tutorial: Azure Service Bus integration.

Sample: sales orders from a web API

Classes DEVIntegTutorialWebSalesLoad / DEVIntegTutorialWebSalesProcess poll an external REST API incrementally. The raw response becomes a parent message; every order in it becomes a child message with staging data, processed in parallel batch tasks. This gives order-level error isolation (one bad order doesn't block the batch) and full traceability from the sales order back to the original API response.
