API keys are used to authenticate requests to the Stripe API. See technical documentation on how to create, reveal, delete, and roll/change API keys
Users with Administrator permissions can access a Stripe account’s API keys in the Developers Dashboard.
If you do not have access, you can ask your Administrator to grant you permissions.
You can reveal a secret key as many times as needed in test mode.
For security, in live mode Stripe only shows you a secret or restricted API key one time. Store the key in a safe place where you won’t lose it.
If you lose the key, you can roll it/change it, or delete it and create another.
