Use REST V2 Connector to interact with web service applications built on REST architecture. You can use REST V2 Connector in a Source transformation, Target transformation, or midstream in a Web Services transformation.

REST V2 Connector supports Swagger specification 2.0 and OpenAPI 3.0.x that helps to interact with web service applications. The Swagger or OpenAPI specification file must be in JSON format.

You can use REST V2 Connector midstream in a mapping to pass a single or multiple requests to a web service application and process the response data. You can also pass data obtained from multiple transformations in the mapping pipeline and process the data.

When you use REST V2 Connector midstream in a mapping, you first create a business service for the operation that you want to perform in the web service application. You then associate the business service in a Web Services transformation midstream in a mapping to read from or write data to the web service application. For example, you can use REST V2 Connector as a midstream transformation to perform PUT operation on a web service application.

You can switch mappings to advanced mode to include transformations and functions that enable advanced functionality.
