トッピックとアクションは別々のものだと思います。トッピックでアクションで削除すると、トッピックとアクションの関係が切り離されるだけで、アクションは削除されてないと思います。

既にアクションはあるので、アクションを再度呼び出せばいいと思う。

Issue with Configure an Agentforce Service Agent Step -

I was having this same issue. I went to setup, actions, then found the actions I created and deleted them. Once I did that, I didn't get the error anymore and I was able to move forward.

When I try to create a new Agent Action why do I get a warning about a new API Name?

This action's API name is already in use...

Hi I am not able to continue because of this message "This action's API name is already in use..." see attached

is there any way to recover api names!

Create an Agent Action (in agent builder)

切断する

This action’s API name is already in use. Go back, enter a unique API name, and try again.

私も同じ問題を抱えていました。セットアップ、アクションに移動して、作成したアクションを見つけて削除しました。それを実行すると、エラーは発生しなくなり、先に進むことができました。

I will try to create a new playground later and see if will works.
