Web API
Bright Pattern integration with the Dynamics 365 web client is powered by Microsoft’s Web API for Dynamics 365 for Customer Engagement apps (version 9.x). A RESTful API, the Web API enables you to interact with Dynamics 365 data for Customer Engagement apps using various platforms, programming languages, and devices.
The Web API implements the OData (Open Data Protocol), version 4.0, an OASIS standard for building and consuming RESTful APIs over rich data sources. For more information on the Web API, see Microsoft’s Developer Documentation.�
