Publish Content Items in Marketing Cloud Growth

When you upload a content item to your content workspace, you can’t use it in messages until you publish it.

To publish content, issue a POST request to the /services/data/v61.0/connect/cms/contents/publish endpoint. The body of the request must contain an array called contentIds. Each item in the array is the content ID (managedContentId) of a content item that you want to publish.

If the request is successful, the response includes a publish date and deployment ID.
