All Email API endpoints requests are authenticated using HTTPS Basic Auth. It requires you to provide a username and a password for each API request.

• Username: Public API Key
• Password: Private API Key

With Mailjet's API, you can grant full access to your account or create subaccounts to separate your mailings across different API keys for easier management, account sharing, and reporting.

Based on your current subscription plan, you are able to create one Primary API Key and one subaccount api key. If you need more, please upgrade your subscription plan.

1. Log into the Mailjet Dashboard.
2. Click on Account Settings.
3. Select API Keys and click on the eye icon next to Private API Key.
