05-MAR-2019 - Early Return Locked-in Items
We’ve updated the Checkouts API to allow you to early return a title even after a format has been locked in. This means that the earlyReturn action will always populate after you make a successful checkout.
We’ve updated our documentation on the Checkouts API page to reflect this. To view our original announcement about this update, please see our previous blog post here.
