API Keys

To access the Proof Business or Real Estate APIs, you'll need an API key. Once you create an API key, simply include it as the ApiKey header in your requests (case-sensitive).

Creating a Production API Key

API Keys can be created instantly from Settings >> API Keys in your Business Account.

If you're unable to find API key settings in your account, you may need to upgrade your plan. Reach out to [email protected], or your dedicated Customer Success Manager.

Creating a Fairfax (Test) API Key

Follow the same instructions for creating a production API key, but in your Fairfax account. To gain access to our Fairfax environment, contact [email protected], or your dedicated Customer Success Manager.

Types of API Keys

• Full Access: lets the caller create, update, and delete transactions. Meant to be secret and for internal code usage only.
• Client Only: only lets the caller create transactions. Intended for usage in client-facing applications, and thus can be freely exposed. EasyLinks are centered on Client-Only API Keys.
