Open Data Protocol (OData) is an OASIS standard that defines best practices to build and consume RESTful APIs.
You can focus on business logic and build RESTful APIs with OData instead of defining request headers, response headers, status codes, HTTP methods, URL conventions, media types, payload formats and the query options. OData guides you to track changes and define functions, or actions for reusable procedures and send asynchronous, or batch requests. Use OData for extension and to fulfill any custom needs of your RESTful APIs. OData builds on core protocols, such as HTTP and commonly recognized methodologies like REST.
OData Connector integrates Application Integration with systems, such as SharePoint, databases, SAP OData services, and Team Foundation Services. These systems are OData compliant, on-premise compliant or cloud applications compliant. You can use Application Integration to interact with objects that are exposed in an OData service. OData Connector communicates with these systems in the OData protocol. Use the OData Connector to connect to an OData service through restful API calls. Rest calls can be in XML or JSON format. Choose the format that the OData service supports.
Create an OData connection to connect to objects in an OData service. Use the connection in a process to perform multiple activities. You can specify an OData connection in step types such as Assignment and Create.
