Authenticating with the FullContact APIs is accomplished through the use of an API key. You can retrieve and manage your API keys from the Platform. A person.enrich example is shown, but any API will return a 401 status code if unauthorized.
KEEP YOUR API KEYS SECRET
Your API keys are essentially like passwords to access the FullContact API, and should be kept secret. Do not embed them in client-side code or post them in publicly accessible areas such as support forums or GitHub. It is a common and easy mistake to accidentally copy and paste code snippets, including your API key, when seeking help - be sure to remove your API key and any other sensitive information before posting.
