for testing purpose we setup our own appstore, modified the config to redirekt to ours, copy apps.json and categories.json from the nextcloud app store and extend its content with our own categorie and our own app. So far, our categorie and app is displayed but the installation does not work.
For the app there are two field i did not set yet.
#1->certificate “… string”
Are this field mandatory and how to get the certificate and signature for my own app in my appstore?
