As a PSA, remember that the API changes don’t only impact third party apps & accessibility tools, but also your ability to bulk delete or modify your Reddit history. If you intend to delete or modify your previous Reddit posts, be sure to run a tool like Power Delete Suite today before the shut down.
Also remember that as Subreddits went from private to public, there may have been posts and comments you attempted to delete but couldn’t until they went public again. So if you ran these tools, you might want to run it again to make sure you got everything.
You could also use the API the web client uses.
That’s not how APIs work. Third party apps, accessibility tools, and the official Reddit apps all use the same APIs. That’s not going away.
What’s going away is your ability to login so that the APIs will actually return you meaningful data. That is definitely going away for anyone who isn’t Reddit and who doesn’t have deep pockets.
