## Using API key

To configure this credential, you'll need:

- An **API Domain**: If your Mailgun account is based in Europe, select **api.eu.mailgun.net**; otherwise, select **api.mailgun.net**. Refer to [Mailgun Base URLs](https://documentation.mailgun.com/docs/mailgun/api-reference/api-overview#base-url) for more information.
- An **Email Domain**: Enter the email sending domain you're working with. If you have multiple sending domains, refer to [Working with multiple email domains](#working-with-multiple-email-domains) for more information.
- An **API Key**: View your API key in **Settings > API Keys**. Refer to [Mailgun's API Authentication documentation](https://documentation.mailgun.com/docs/mailgun/api-reference/mg-auth) for more detailed instructions.

## Working with multiple email domains

If your Mailgun account includes multiple sending domains, create a separate credential for each email domain you're working with.
