Bulk activate a set of property versions. Alternately, perform a bulk fallback to the previous activation within an hour of the previous bulk activation. Base the set of versions to activate on the results of a bulk patch operation, which you use in this operation's request. This operation launches an asynchronous process to update properties. To check its progress, run the List bulk-activated properties operation, whose link is available in the Location header or bulkActivationLink member of this operation's response. See Bulk Search and Update for overall guidance on this feature.
If your account is enabled for mandatory domain validation, you need to prove ownership of the domains you set up as property hostnames, before activating the property. You can either pre-validate your domains by generating validation challenges or use the challenges you get while adding, listing, or updating your property version hostnames. Learn more.
