YouTube Data API v2 has been completely discontinued.
I wasn’t aware that the v2 API was being discontinued, so the service I was developing was affected and I had to respond urgently.
When I searched for “YouTube Data API v2 discontinuation”, I found that the Google Developer Japan Blog properly mentioned the planned discontinuation.
As long as we use external APIs in our own services, I painfully realized that we need to keep in mind that “the APIs we use won’t necessarily be available forever.”
That’s all from the Gemba.
