Get your API Key
Every API request requires an API key for authentication. To create one:
Log in to your Elastic Email account.
Go to Settings > API.
Click Create API Key, give it a name, and set the permissions you need.
Copy the key and store it somewhere secure, it is only shown once.
For a full walkthrough, see the API Settings guide.
IMPORTANT SECURITY NOTICE: Your API key is like a password. Do not share it with
unauthorized persons or include it in public code repositories. If your key is
compromised, delete it immediately.
