An API key is a unique string of characters (like a code or token) used to authenticate and control access to an Application Programming Interface (API). It functions as a digital passkey, enabling a user, application, or developer to interact with a database or a service platform such as EX.IO, ensuring secure and authorized access.
For instance, when using EX.IO’s API, you would require an API key from https://www.ex.io/apps/api-keys to authenticate your requests.
Important Note: Keep API keys confidential, as sharing them can result in misuse or unauthorized access.”
