The record

Product: GTC Internet-Fax is a cloud fax service for sending and receiving faxes online without a fax machine or fax server.
Sending and receiving: Users can send and receive faxes through a web interface, email, or developer interfaces, and use these methods in parallel.
Email workflow: To send by email, users address a message to the fax number followed by @fax.tc, attach a document, and receive delivery status by email.
API protocols: The product offers REST, SOAP, and SMTP interfaces, with advanced API features such as multiple recipients and scheduled sending.
Developer languages and integrations: The maker lists VB, Java, .NET, C#, and PHP for API use, and separately lists Java, PHP, .NET, Ruby, and Salesforce on its developer page.
Fax reception: Received faxes can be delivered as PDF or TIFF attachments by email or retrieved through the secure fax reception area.
Fax management: The service supports cover sheets, address-book recipients, custom sender IDs, centrally managed users with individual permissions, sending logs, and delivery status notifications.
Automation and scale: The developer page describes a scalable cloud service for automating fax sending from applications, from one fax to one million faxes.
Security and location: The maker says its servers are located in Germany, describes the service as GDPR-compliant, and lists SSL access and IP-range restrictions among its security features.
High-security options: The maker offers a PCI DSS-compliant solution for sending credit-card data, with an extra charge of €0.02 plus VAT per fax page for sending.
Sending limits and billing: Flexible-tariff credits do not expire, only successfully sent pages are charged, and pages taking more than 60 seconds are billed proportionally in six-second increments.
Support: GTC advertises telephone, email, and chat support, with customer advisors based in Stuttgart.
Intended users: The maker presents the service for both small offices and large corporations replacing fax servers, including use through APIs to automate business processes.
