We have implemented ebay sdk core and ebaycall.jar in our app to fetch the order with complete status from ebay channel.
We see the managed payments is not implemented on sandbox so we can't test our existing implementations with the managed payments.
My question are,
Do we need to change the implementation in our app?
Is there any new sdk is introduced to handle the ebay payments?
How refunds get take place with the new ebay payments?
