One of the most frequent issues is misconfigured environment variables. Developers may accidentally commit their API key to a public repository or fail to set it correctly in local or cloud environments... Lastly, forgetting to rotate API keys regularly can be a security risk.
First and foremost is securing your API key. Never commit your API key to a version control system like Git or expose it in client-side code such as in a web browser or mobile app. The recommended approach is to make all API calls from a secure server-side environment where the key can be protected.
