Posting to Facebook Before Payment Made

Hi,

I’ve set up the social importer plugin to integrate with my FB page and when I test it by adding a listing via the front end “as though I am a shop”, my site makes a post to the FB page BEFORE the payment has been completed (using stripe/credit card). It effectively creates a post on FB that shows an error (becuase the post has not been published yet as it’s not been paid)…

What am I missing here in the settings/set up to run the social poster ONLY once the invoice has been paid?

Thanks
Mike
