SocialPostMarkingPublishedNotification

Published before a person marks a channel’s Failed or Unknown result as published (the Mark as published action, or POST targets/{id}/mark-published). A handler can change the live post’s link, or refuse.

The following properties are available within the notification

Property Name	Type	Use
Target	SocialPostTargetInfo	The target, as it is now.
PostUrl	string?	The live post’s link the person gave, or null. Settable.
Messages	EventMessages	Add the message to return when you cancel.
Cancel	bool	Set to true to cancel without a message.

SocialPostTargetInfo (read-only) has these properties:

Property Name	Type	Use
TargetId	int	The post’s target on this channel.
PostId	int	The post’s id.
ChannelKey	Guid	The channel.
Network	string	The channel’s network id.
Status	TargetStatus	The target’s status.
Attempt	int	The attempt number (0 for the first).

Cancelling

Call CancelOperation(new EventMessage(category, message, EventMessageType.Error)). Nothing changes, and the result is target.cancelled:<message>.

Rules

• The target must exist, not be sealed and be Failed or Unknown (target.not_found, post.sealed, target.not_resolvable); those checks run first.
• PostUrl must stay an absolute https URL (or null): checked before the handlers and again after them (link.https_required).

SocialPostMarkedPublishedNotification is published after the save.
