What is it?

The Campaign Public API now supports cloning and asset type listing. Four new endpoints give developers full control over campaign management outside the HubSpot app:

• - List Asset Types: Retrieve all asset types available to associate to a campaign, including custom objects
• - Clone Campaign: Clone a campaign and its associated assets by providing a Campaign GUID, a new name, and the assets to replicate
• - List Cloneable Assets: See all assets eligible to clone within a specific campaign
• - Cloning Status: Check the status of an in-progress cloning operation

Why does it matter?

The Campaign API previously couldn't match what users could do in-app. Developers had to jump between docs, portals, and endpoints just to retrieve data and make requests. These endpoints close that gap, enabling end-to-end campaign management workflows without ever leaving the API.

How does it work?

List Asset Type: Make a call to List Asset Types to retrieve all assets possible to associate to a campaign. Then use those to make requests to Retrieve Assets or Add Asset endpoints.

Cloning: Provide the Campaign GUID of the campaign you wish to clone, the name of the new campaign and specify the assets from the original campaign you wish to replicate.
