Success stories: Hear directly from our partners
The NFON API impressed us with its clear structure and high reliability. Thanks to the flexible interfaces, we were able to efficiently implement our ideas and automate processes that were previously very time-consuming. This led to the creation of our own tool, Portalblitz, which significantly simplifies the management of extensions, groups, queues, and time schedules.
Thanks to the NFON CTI API, we were able to seamlessly connect our PowerWeiss software with NFON Cloud Telephony in a very short time. The simple integration enabled us to quickly offer our customers real added value.
For us, connecting the NFON APIs to our CRM system SYNCCESS worked without any problems.
