Report phishing websites to Steam and CloudFlare

Webhook to report through Mailgun phishing websites to Steam and CloudFlare (if the domain is on CloudFlare) You have to set the Credentials for webhook and Mailgun. You have to set the email from for Mailgun. This assumes it is running in n8n's Docker image where bind-tools is not readily available but installable.

Help me set up the n8n workflow "Report phishing websites to Steam and CloudFlare" (https://n8n.io/workflows/122). It uses: Mailgun. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
