What is the “Correlation ID” field in the API used for?

This field contains an alphanumeric string that allows PayPal to track every API call attempt. Every PayPal API response includes a Correlation ID field. If you contact PayPal with any questions regarding a specific API call, provide this value either in your support request or by attaching the log file to the ticket you create.
