Currently, the Givebutter API for creating and updating campaigns does not allow setting a campaign’s published date. The existing timestamps are:

"created_at" – when the campaign was created

"updated_at" – when the campaign was last updated

"end_at" – when the campaign ends

We would like a new field, published_at, that can be manually set by the user. This would allow campaigns to be scheduled to go live at a specific date and time, rather than being published immediately.
