Since AX 2009, Dynamicweb has been integrating with this ERP using web services through the Application Integration Framework (AIF). With the release of the cloud version of AX, AIF has been replaced with OData (Open Data). This standard protocol allows external access to AX data and business objects using RESTful web services. This is a significant improvement over the proprietary AIF (SOAP based) since RESTful api’s are more efficient when it comes to bandwidth utilization. Since an AX-integrated Dynamicweb B2B e-commerce solution may want to provide live lookups to specific pricing, inventory and product assortments, accessing the AX server frequently (based on website traffic) may be required, and now OData for D365 Operations supports optimized data interchange.
