Still the most secure method

To-date, fax remains the most reliable and secure way of sending sensitive and official documents. The Cloud Fax API allows you to send and receive documents via fax directly from your application or e-mail client to any device anywhere. Documents are sent with the highest security without needing to install plugins.

This API helps you to...

Send sensitive official documents securely

Start sending privacy-sensitive documents – such as contracts, court papers and identity documents through fax to make sure they arrive safely.

Be fully compliant with regulations

Become fully compliant with data and privacy regulations in any sector, whether it’s the healthcare, financial, governmental or private sectors (GDPR, MiFID 2, PCI DSS, etc.).

Optimize your file sending workflow

Integrate the Cloud Fax API directly into your existing application or e-mail client to send faxes and SMSes efficiently and without any effort.

How it works

The Cloud Fax API allows you to effortlessly send and receive fax directly from your application or e-mail client (e.g. Outlook). A confirmation is sent via e-mail. You can use any device connected to the internet and you do not need to install any application or plugin. You can also use this API to send SMSes.

Upon registration, you receive your own local fax number for sending and receiving. You can also assign your existing fax number to your user account. It is as simple as that.



Sends documents and sensitive information with an authorized, time-stamped and digitally signed transmission certificate.
