Mailgun uses API keys for authentication. When you connect your Mailgun account, Pipedream securely stores the keys so you can easily authenticate to Mailgun APIs in both code and no-code steps.

Get your API Key in the Control Panel, specifically in Settings > API Keys. More info in docs.

If your Mailgun account resides in the EU, choose the EU option in the Region field. Otherwise, choose the US (non-EU) region.
