Hey @mekirile

Currently, the API key for a project can’t be changed either in the UI project settings or by Amplitude backend.
There have been conversations about the ability for the secret key to be changed on the backend on per project basis, but looks like the change in API key isn’t supported yet.

Here are a few posts :

Quoting from one of the above posts :

“ Regarding API keys, our engineering team is not willing to allow for changes with API keys since it affects ingestion and data loss if misused. API keys are also by nature public so it shouldn't matter (anyone can look at outgoing traffic from a device and see the API key). Therefore we are not supporting changing API keys at the moment.

Regarding secret keys, we are able to re-generate your project's secret key on the backend with the approval of an Admin.”
