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.
