These four are written and tested, and none of them is on the list above. Duta names a channel as working only once a real post has gone out through it and a stranger could see it.

Duta has published real videos to TikTok and they arrived. Until TikTok has audited the application it forces every post made through the API to private, so the account holder sees them and nobody else does. That is why it is not listed as a working channel.

Every part of it is proved except the last: the account is connected, boards are read from Pinterest on demand, and the scheduler fires on time. Pinterest then refuses the Pin because the application still has trial access rather than standard access.
YouTubeWaiting on Google’s review
Written and tested, and has never published. It needs a Google consent screen that Google has verified before a channel can be connected at all.
Google Business ProfileWaiting on Google’s review
Written and tested, and has never published. A new Google project starts with no quota for this API at all, so the first request has to be granted before there is anything to test against.
