Hear directly from our partners.
The NFON API impressed us with its clear structure and high reliability. We are 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 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.
All the details about the NFON APIs
With the NFON APIs, you can integrate key NFON services directly into your own applications, portals, and business processes. This allows you to develop tailored solutions for your company and your customers, automate workflows, and seamlessly connect third-party systems with the NFON platform.
For a quick introduction, the NFON API Showcase provides a practical overview of how the APIs can be used. The available source code can serve as a basis for your own integrations and can be adapted and further developed to suit your requirements.
Three APIs are currently available and are continuously being developed and expanded with additional functionality:
1. Portal API
The Portal API makes key functions of the NFON Admin Portal available via an API. Depending on the use case, access is provided at K-account or S-account level.
K-account level – tailored customer solutions
Access to an individual K-account is suitable for applications developed specifically for a customer environment. One possible use case is synchronising the NFON address book with third-party systems such as Microsoft Outlook or Salesforce.
S-account level – centralised partner solutions
At S-account level, NFON partners can centrally manage their customers’ K-accounts. This makes it possible, for example, to automatically apply standardised settings across multiple customer environments or create custom administration processes that go beyond the capabilities of the Admin Portal.
2. Call History API
The Call History API provides access to call data for an individual user. Authentication is handled via “Login with NFON”, which is integrated into the respective third-party application.
After a successful login, the application receives an access token and can retrieve the call data that the user has authorised for access. This makes it possible, for example, to automatically store and further process call summaries in systems such as DATEV or Salesforce.
3. CTI API
The CTI API enables the control and analysis of key telephony functions across the entire phone system or K-account.
This allows partners, among other things, to:
develop real-time dashboards for incoming and outgoing calls,
display incoming calls together with contact details in CRM systems,
initiate calls directly from a third-party application,
automatically document and store telephony activities.
The CTI API therefore provides the foundation for comprehensive telephony integrations with CRM, ERP, and other business applications.
