We've just upgraded to the new version of Yahoo Japan Search's API which contains the new metric, Conversion Value.
If you haven't already, you'll need to reconnect your Yahoo Japan Search source(s) before August 3rd to continue syncing this data with Funnel.
To obtain the new Conversion Value metric, you'll need to ensure that this field is selected when connecting your account.
You can learn more about the data you can obtain from Yahoo Japan Search in this article.
We hope that you find this update useful. If you have any questions or if you would like to see historic data for Conversion Value, please contact firstname.lastname@example.org and we'll be happy to help.
