How to generate an API key
To use the Legalesign API, your account must first be verified. Read this article on how to get verified for API access.
Once verified, use your Legalesign account credentials to log into the Developer Portal where you can generate your API Key - https://developer.legalesign.com/.
Go the Api Keys section. In the form starting with a text field labelled "Key name" enter a name, any name of your choosing, then select the interface for the key you will use (REST, GraphQL, or both), add an optional expiry date (recommended) and then click 'Create Key'.
Copy this key when it is shown to you, it cannot be shown again.

Add the key to your Authorization headers starting 'Bearer YourApiKey' - Go to the Quickstart section for copy and paste samples to confirm your key is working.
