The Google Indexing API is failing for me, and I use it legit for job posts.

I can send a link and it shows successful, but when I try and get the notification status to see if the link was successfully sent I get an error.

I think Google made the API application only now (?)- https://x.com/bdlowery2/status/1838454619913302503

Is anyone else having this problem? I just want to confirm I'm not the only one.
