How do I upsert multiple records using JSON/XML with REST API?
I am writing a .NET application that calls REST API to retreive and upsert records to my SFDC. I've figured out the retreive part but I am unable to find out how to upsert thousands of records at once using the REST API. How do I pass the mapping file and how to feed my csv file so that it upserts? Your help would be much appreciated.
