+Using the updated synchronisation method
+========================================
+
+If you have a lot of products, the eBay API can sometimes refuse some synchronization
+calls due to a time-based limit on the number of requests that eBay enforces.
+
+To fix this issue, a new implementation mechanism has been developped; however this
+updated mechanism is disabled by default to avoid having the 2 systems running in
+parallel in existing installations.
+
+To switch to the new synchronization mechanism:
+
+#. Enable the Developper Mode by going to :menuselection:`Settings --> Activate the developer mode`
+#. Go to :menuselection:`Settings --> Technical --> Scheduled Actions`
+#. Archive the old synchronization actions (both are named *Ebay: update product status*)
+#. Activate the new synchronization actions (*Ebay: get new orders* which runs every 15min by default and *Ebay: synchronise stock (for 'get new orders' synchronisation)* which runs once a day per default)
+#. Ensure that the **Next Execution Date** for both these actions are in the near future
+
+Starting with the next execution date, the new method will be used instead of the old one.
