I requested a written status on this and got it. Here's what they confirmed:
the current
ebay sync will copy all listings from
ebay and add any new listings added to
ebay.
It will not propagate edits - e.g., if you change a price that will not be reflected in Hipstamp
They cannot get access to the SKU/custom id and though they are looking for a solution, they have no date by which this will be fixed
Items sold on hip are not deleted on
ebay - must be done manually
Bottom line, the only real functionality is:
1) 1 time bulk copy from
ebay (excluding SKU)
2) new items copied from
ebay (excluding SKU)
3) items sold on
ebay are deleted on hipstamp
TBD:
a) delete from
ebay when hipstamp item sells
b) copy edits
c) capture SKU
