DSTax ITBridge Hosted, RESTful Indirect Tax Integrations

DSTax Technology has developed this hosted, RESTful API solution under the ITBridge banner. The ITBridge solutions allow for your source systems to integrate with either ONESOURCE Indirect Tax Determination (“OSITD”) or ONESOURCE Fast Sales Tax for indirect tax calculations. Both of these offerings are available as hosted solutions, minimizing your own internal integration development efforts and ongoing maintenance responsibilities.

Description of Operations

The client can send an HTTP request to ITBridge that contains the relevant transaction information: sales price, shipping costs, shipping address, billing address, etc. in JSON format. ITBridge receives this information in the form of a Flask request object and uses this data, along with settings configurable through the web interface, to build the SOAP envelope and XML for an OSITD tax request using the yattag library. The requests library is used to send this SOAP envelope to the endpoint corresponding to the OSITD WSDL specified in the settings. ITBridge receives the OSITD tax response as a request response object. It removes the SOAP envelop and uses Flask to send the tax response XML back which parses the XML for relevant tax data to save back to the client’s source system.
