When you have connected an Extranet (Viator, GetYourGuide, Expedia, Musement) you can then create products on them directly from Magpie. You should see a list similar to below:
Click on the Create on "extranet" button and Magpie will create that product on the connected extranet account. We send many fields of content including all of the time consuming fields such as Descriptions, Highlights, Inclusion, Exclusions etc. You will still need to go to the product on the Reseller extranet to set up your availability and any setting Magpie does not have access to.
Your product is also now mapped meaning you can push content updates from Magpie directly into that product on the extranet in the future.
