Social Publishing Webhooks

Hi, 

I am investigating Lithium Social Publishing for a client. My client would like to create and schedule posts in Lithium and then have the scheduled posts checked programmatically for appropriateness, accuracy, etc. before creating a response to either approve or reject the post. 

We've done this type of integration with other publishing clients where webhooks are sent from the publisher, our system analyzes the content, and then sends an approve/reject response back to the publisher.

Is this possible with Lithium? I couldn't find anything in the API or product documentation that would confirm. Thanks!
