Correlation ID: Tracking Transactions to Reconcile Bank Records
When working with the Dwolla API, correlating Dwolla resources to your own system can be difficult to track. Having a common “tag” among elements in a created resource allows for a common reference, which can be handy when logging and auditing payments, ultimately allowing you to spend more time fixing the problem rather than finding the problem.
The Correlation ID value can be specified on API requests to create a Dwolla Transfer or Customer resource. Whether you use this optional parameter to correlate internal transfers, order confirmation numbers, business IDs—or even a timestamp—its simplicity provides a lot of power.

Better Payment Management
Ensure the transaction information within your database aligns with what’s occurring on the Dwolla Platform. Using a Correlation ID can improve the traceability of a transaction between two systems.
