This article provides a brief overview of the Magento cloud provider for UniDAC used to access Magento from Delphi and Lazarus. You will find the description of some useful features and how to get started quickly.
Main features of Magento cloud provider are:
The full list of Cloud provider features can be found on the UniDAC features page.
Both Professional and Standard Editions of UniDAC include the Magento cloud provider.
Magento provider supports Magento data types and API.
Applications that use the Magento cloud provider require Devart ODBC Driver for Magento to be installed on the client computer. The driver is sold and distributed separately from UniDAC.
When an application was built without runtime packages (Link with runtime packages set to False in Project Options), you do not need to deploy any BPL files with it. For more information, see Deployment.
Note that UniDAC Trial requires deployment of additional BPL files regardless of Link with runtime packages.
To connect to Magento 1.x using Devart ODBC Driver, you should configure the driver and set up a DSN. In the TUniConnection component, specify the following parameters:

To connect to Magento 2.x using Devart ODBC Driver, you should configure the driver and set up a DSN. In the TUniConnection component, specify the following parameters:

Though UniDAC is components that provide a unified interface to work with various cloud services, it also lets you tune behaviour for each cloud individually. For thin setup of a certain cloud, UniDAC provides specific options. These options can be applied to such components as TUniConnection, TUniQuery, TUniTable, TUniStoredProc, TUniSQL, TUniScript via their SpecificOptions property. SpecificOptions is a sting list.
