post https://uat-fundapi.stockal.com/fund/customer/transaction/upload-doc
This API needs to be called only after the confirmation on the payment received at Stockal's end and not prior to that. Bank statement should contain the transaction done as part of the payment. User can upload max of 4 documents at a stretch.
This API could also be be used to be able to re-upload the document if the transaction is on hold due to unavailability of any document. Everytime a re-upload is being done - the transaction will need to be resubmitted using Submit Transaction API
