First, navigate to Feed Tool > Feeds > API Feeds and click + Add Feed:
Next, click Activate in the bottom right corner of the Additional Countries box:
NOTE: if all of your plans available Feed Channels are used, you will be prompted to upgrade your plan. Once the upgrade has been completed, you'll be able to continue creating your new feed.
Next, name your new feed and select which Channel to target:
Google: Feed currency is automatically converted in your Merchant Center account. Simply select the Country you wish to target and click Save.
Bing: Feed currency must be set within the app as Bing Merchant Center does not automatically handle conversions. (See Below)
Name your feed
Select Bing as your target
Select your Target Country
IMPORTANT: Feed Currency must be set to the currency of the target country
Finish up by setting Convert Price to YES and then clicking SAVE
NOTE: Each target channel count towards your "Feed Channels." For example, if you want to target the UK on Google and Bing that counts as 2 feeds. Keep this in mind if adjusting your Feed Tool plan.
