API Key

An API key is a unique identifier used to authenticate a client attempting to access an API. It acts as a secret token that grants permissions and tracks the usage of API requests. API keys are essential for securing and managing access to APIs, ensuring that only authorized applications can interact with the services provided. They help in monitoring and controlling the API usage, preventing abuse, and ensuring that the API is used in accordance with the provider’s policies. Typically, API keys are generated by the API provider and distributed to developers. They must be included in API requests, usually as a query parameter or in the request header. While API keys offer a basic level of security, they are often used in conjunction with other authentication methods, such as OAuth, to enhance security. Proper management and protection of API keys are crucial to prevent unauthorized access and potential data breaches.
