What is an API key?

An API key is a unique identifier that allows your software to securely interact with Layer4's services. By assigning distinct keys to different parts of your system, such as various applications or specific areas within your infrastructure, you can enhance both security and organization.

API keys can be configured with expiration dates, up to a maximum of one year. This ensures that a key will automatically become invalid after the specified period, adding an additional layer of security. Despite this feature, it is advisable to rotate your API keys more frequently than their expiration dates. Regular key rotation minimizes the risk of unauthorized access, maintaining the security of your connection to Layer4. This practice is similar to regularly updating your passwords to enhance security.
