Action Authentication

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.
