Which demos do you mean?
Yes, I’m using it on a website with 100k+ visits per month.
It’s a WordPress plugin, so no other CMS.
I think his issue is the new Guttenberg editor breaks the forms and as such the plugin no longer functions.
Shame I only just found this as there appears to only be one other plugin like this.
Thanks for reporting. A PR is welcome!

Can I create something like additional field/excerpt and export it as an JSON ?
that is, for example instead of the whole post i would like to have content that is in a new separate field ?
button -> create new topic
Type title:
Custom field: —> json
category/tags:
content
If you can retrieve the data needed with a SQL query through Data Explorer plugin, then you can read it as JSON with this plugin as well.
Not sure if you’re still maintaining this plugin, but I submitted a PR to support the header-based API authentication required in 2.5

Ich habe das Plugin Open Source gemacht und aufgehört, daran zu arbeiten, da das Interesse der Leute gering war.
Ich bin mir nicht sicher, wie der aktuelle Stand des Plugins ist, aber es konnte das früher.
