Sending emails / Creating Campaigns with dynamic content using REST API? [Locally hosted]

Hey everyone.
According to this Github doc, the only Rest API calls that are available are for managing lists and subscribers.

https://github.com/phpList/rest-api/blob/master/docs/Api/RestApi.apib

How come there are no Campaign creating API calls? We have a content creation website and what we are trying to achieve is fully automated system for creating campaigns that notify our subscribers of new content. So every time we push “publish a video” we want to automatically create a campaign, populate it with the dynamic content like Video Title, Description, Thumbnail image and links and send it off to the emailing queue to our subscribers. Is that possible?

I see this very often with other email client tools. You only get API calls for managing subscribers, which frankly I already do using PHP and MySQL.

Any way to achieve this with phpList? Thanks everyone for the help.

@MilesThatch You might want to look at the older, now unsupported, plugin that does support sending a campaign https://resources.phplist.com/plugin/restapi

Ah, I see. thank you for a quick reply! How come the new API does not offer this? Seems like pretty major functionality to leave out for automation.
