Trustpilot automation with completed purcase

I’ve recently set up a Trustpilot account. Trustpilot encourage confirmed purchase reviews, therefore a link to leave a starred review after every purchase. I have been emailing the Cliniko tech team to see if this is something that could be done with Cliniko when an invoice is completed and unfortunately it’s not something that is doable at present. I think this would be a very useful feature for many practitioners to help grow their online presence and build trust with potential new patients.
