# Mailjet credentials

You can use these credentials to authenticate the following nodes:

- [Mailjet](/08-0-0-Workflow/integrations/builtin/app-nodes/n8n-nodes-base.mailjet.md)
- [Mailjet Trigger](/08-0-0-Workflow/integrations/builtin/trigger-nodes/n8n-nodes-base.mailjettrigger.md)

## Prerequisites

Create a [Mailjet](https://www.mailjet.com/) account.

## Supported authentication methods

- Email API key: For use with Mailjet's Email API
- SMS token: For use with Mailjet's SMS API

## Related resources

Refer to [Mailjet's Email API documentation](https://dev.mailjet.com/email/guides/) and [Mailjet's SMS API documentation](https://dev.mailjet.com/sms/reference/send-message/) for more information about each service.

## Using Email API key

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.

## Using SMS Token

To configure this credential, you'll need:

- An access **Token**: Generate a new token from Mailjet's [SMS Dashboard](https://app.mailjet.com/sms).
