We need to collect varying recurring amounts using PayPal referenced transactions through Virtual Terminal.
e.g. [url removed, login to view]
The references and amounts in GBP for collection, are available from a spreadsheet downloaded from Zencart.
This spreadsheet to be submitted to Paypal and populated with the results of the transaction attempt.
If there are any failed collections then the spreadsheet to be re-submitted, at a later date, so that only failed collections can be re-attempted and the procedure repeated.
When transactions are successful the new reference to be written to the Zencart Mysql to keep the references usable for the next month.
All results during the view and submit stages must be captured and shown on the spreadsheet, including warnings of "card expired" etc.
You must have experience of Paypals referenced transactions and the project must be fully completed.
