Are there SMM services with their own API for interacting with the site?

Question

SMM

I am looking for a service for cross-posting on a social network, which would have its own API for interacting with the site. For example: according to the schedule, a post is published on social networks, and at the same time it is published on the site.
Ideally, of course, the service itself would send notifications (a la webhook), but polling once an hour for the crown of the list of published posts is also suitable.
Yes, it would be possible to "stick" to one of the social networks and pull each post from there, but exactly the option described above is required. Thank you.

Answer 1

It is very dreary to maintain such a service and there is little demand,
use the plugin for vp, for example, ready
