Hi Shakila, Since we are looking at quite a lot of parameters, you can use script mediator for this purpose.
Jusy have a single variable inside the script mediator for this Similar sample can be found in [1] [1] https://github.com/wso2-dev/esb-connectors/blob/master/freshbook/freshbooks-connector/freshbooks-connector-1.0.0/org.wso2.carbon.connector/src/main/resources/freshbooks-client/listClients.xml Best Regards, Malaka On Thu, Nov 27, 2014 at 2:44 PM, Shakila Sivagnanarajah <[email protected]> wrote: > Hi All, > > I am developing connector for Nest API.
