Our free APIs

There are 2 APIs which are available to any Popfax customer at no cost. The APIs use the client’s credentials in order to exchange data and information with the Popfax.com application.

  • SMTP (fax sending and its extension for SMS sending). Reception is handled by e-mail, by default, without any action via the API. (www.freepopfax.com uses 100% SMTP API).
  • HTTPS (SOAP Web services): the same as above plus some functions to manage account settings and to retrieve account elements (history...). PopCompanion is SOAP API based.
