Hi @Mohammad_Mithani, It looks like Eric’s use case involved sending bank to bank transfers between two different users. The receiving Customer’s funding source(bank account) needed extra data that could be tied to that resource to be used by his application. Eric was able to add additional data to the Transfer itself instead of to the
bank funding source attached to the receiving Customer with the use of metadata.
Metadata can be attached to a transfer between two different Customer accounts and be used by your app for various reasons. For example, additional information that can be used by your app to correlate it to something your app knows/uses separate of the Dwolla API.
