As a workaround, you can actually include our product in a composer file.
I did not try it myself, but when you’re logged in, you can have a look at the download section and the structure of the download links. It will look like this
https://api.admincolumns.com/?command=download&subscription_key={yourkey}&product_key={basename}&version={version}
Where you have to fill in the variables yourself.
yourkey: The license key for your subscriptions. I advise you to store this in an Environment variable
basename: the basename of the plugin you’re trying to receive: admin-columns-pro
or ac-addon-acf
version: The specific version that you want to retrieve, leave empty or omit for the latest version
In order to get the latest version for our products, you could try to filter that from this API call.
