Question: Composite requests allow you to make multiple HTTP requests with a single call. Can I use a composite request strategy to create a POST request for new records and switch to a PUT request for existing records?
Answer: You can build composite requests in integrator.io; however, they can't handle if/then statements to select one statement vs. another within a single request. In such situations, you can build two separate import steps (one with each call), and use filters to process each record to send to whichever import it needs to go to.
