Authenticating with the FullContact API is accomplished through the use of an API key.
You can generate and manage your API keys from the Fullcontact Platform UI

When accessing the FullContact API, include your API Key within the "Authorization" header of your POST,
using a prefix of "Bearer". An example of this is shown below.

curl -X POST \
 -H 'Authorization: Bearer {Your API Key}' \
 -H 'Content-Type: application/json' \
 -d '{"email": "[email protected]"}'


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.
