## Using Email API key <a href="#using-email-api-key" id="using-email-api-key"></a>

To configure this credential, you'll need:

* An **API Key**: View and generate API keys in your Mailjet [API Key Management](https://app.mailjet.com/signin) page.
* A **Secret Key**: View your API Secret Keys in your Mailjet [API Key Management](https://app.mailjet.com/signin) page.
* *Optional:* Select whether to use **Sandbox Mode** for calls made using this credential. When turned on, all API calls use Sandbox mode: the API will still validate the payloads but won't deliver the actual messages. This can be useful to troubleshoot any payload error messages without actually sending messages. Refer to Mailjet's [Sandbox Mode documentation](https://dev.mailjet.com/email/guides/send-api-v31/#sandbox-mode) for more information.

For this credential, you can use either:

* Mailjet's primary API key and secret key
* A subaccount API key and secret key

Refer to Mailjet's [How to create a subaccount (or additional API key) documentation](https://documentation.mailjet.com/hc/en-us/articles/360042561974-How-to-create-a-subaccount-or-additional-API-Key) for detailed instructions on creating more API keys. Refer to [What are subaccounts and how does it help me?](https://documentation.mailjet.com/hc/en-us/articles/360042561854-What-are-subaccounts-and-how-does-it-help-me) page for more information on Mailjet subaccounts and when you might want to use one.
