In order to help organizations wishing to migrate away from hardware-based fax machines, as well as to support software developers who are building solutions to facilitate this, Denphone has released a fax REST API service.

Denphone's fax REST API service is both secure and reliable, and combined with our Denphone Hikari service, allows the use of Denphone-supplied Japanese fixed-line 0ABJ phone numbers (e.g. 03 for Tokyo 23 wards). It can also be used with a Denphone-supplied Japanese IP phone number (i.e. 050 number) over the public internet.

Compared to other fax REST API service providers, Denphone's tariff rates are lower and developer support is bilingual and more comprehensive.
