API Key for custom Field was updated automatically

Hi,
A few days ago I noticed I had an error when the form on site was submitted. I found out that the problem was that the Field API Key was different in my program and in Pipedrive. Everything works well now because I changed the API Key in code.
But it looks like API Key has been changed automatically. Is it possible that the API Key was changed by itself?
Just to be sure that I won’t have such an issue in the future.
Thanks

Hi @AlexAk

Field API Keys shouldn’t be changed so this definitely sounds strange. I would recommend contacting our support so they can look at your account specifically to see if something was somehow changed.
