When viewing or editing a package from Partner Center > Marketplace > Manage Store, packages with the Add to Shopping Cart option on the Store button behavior setting will display a shortened URL that can be copied by clicking the Copy link button.
Following this URL will automatically add the package to a user's Shopping Cart and direct them to the Cart Contents page, where they can review the package and begin checkout.
For users who are already signed in, the link will take them directly to their Cart Contents page in Business App. For users who are not signed in, or who do not already have an account, they will land on a page where they can sign in or easily create an account before reviewing their Cart Contents page.
Using the "Buy it now" link, partners can easily direct prospects or customers to any package from a link or button on their public website, an email conversation, a text message, or anywhere you can share a link.
