Hi all,
we are in the review process of our app.
One criterion is that, on uninstall, all recurring fees must automatically be terminated.
Since we are a SaaS platform with its own charges, we did not use managed billing, but implemented our own billing via the shopify billing API.
So, we are listening on the uninstall webhook and try to remove the recurring fees.
But here, the app is already uninstalled, thus the request is unauthorized.
Therefore the question:
Using the Billing API, how do we remove recurring fees on app uninstall?
Thanks for your time!
