Fill in user and event information for Square payments transactions
Square transactions (when using Square for mobile payment) do not include the Name, ItemTitle and InvoiceNumber fields. (They are included in PayPal transactions. Examples attached). The CustomerID, CustomerName and Customer ReferenceID fields are not currently being used.
Unfortunately we can’t provide this information due to limitations in Square’s integration interface.
As for invoice number – if you are talking about Wild apricot’s one it will be displayed in a “Description” column. Your Wild Apricot application should be 1.7.1 version or higher in order to record it.
