Hi Deepti,
Actually, in my case, I passed the country Id as a parameter to the child pipeline. I prepared a sheet (excel) containing the list of countries and the corresponding country Id. I loaded the sheet in the child pipeline’s file reader. In the parent pipeline, I specified all those countries in the ‘;’ separated format, so that during each run, the countries are passed into the child pipeline one by one.
Then I used the mapper and specified the REST API path. According to my use case, each time we need to change the country ID in the REST API depending on the upcoming country fed by the parent pipeline and this can be achieved using the normal mapping function.
