The following are the automatic revisions that are run on a schedule:
This process updates any stock changes in the previous 15 minutes to your warehouse quantity. Stock will only update on eBay if the quantiy has fallen below what is currently listed. Refer to stock control page on how thesholds and levels work.
GetTransactions (instantly if notification token is set)
SendInvoice (instantly if notification token is set)
To automatically update your pricing, description and other product fields that you change you can set full revisions to run at night.
Goto eBay > setup > settings > Revise all eBay listings on this day > set which day/days to revise
By default it is set to everyday but if you have a large number of products or do not wish to revise each night you can change it to once a week or never.
Note that only fields that have been changed since last revision will be updated to eBay. For example all images are not reuploaded but rather ones that have been changed.
