API integrations

Most telephony providers offer a generic public API with hundreds of endpoints. You spend days reading documentation, writing code, testing, and often discover at the end that the API does not do exactly what you need. CallFactory takes a different approach.

Our API is private. You tell us what you want to achieve — which data you need, which actions you want to trigger, how your system should interact with your phone numbers. We verify that it is feasible, and then we build and deploy the endpoints for you. Your developer receives clean, documented endpoints that do exactly what was agreed. No guesswork, no wasted hours, no dead ends.

One of the most powerful API use cases is dynamic call routing. Instead of managing routing rules in our dashboard, your own software decides where calls go — in real time.

For example, your company uses a calendar or internal planning tool that knows exactly who is on duty, when, and where. You write software against our API endpoint that reads your schedule and automatically updates call forwarding destinations throughout the day. At 9 AM calls go to the office, at 1 PM they forward to the mobile of the colleague on afternoon shift, at 6 PM they go to voicemail. The logic lives in your software, the telephony runs on CallFactory — giving you complete control and flexibility.

The API lets you trigger outbound calls programmatically. Your system initiates the call, CallFactory dials the number, and the recipient hears a recorded message or a text-to-speech message that you define.

Common use cases include appointment reminders that call the patient an hour before their slot, delivery notifications that confirm arrival time, service alerts that notify on-call engineers of a system issue, and emergency broadcasts that reach an entire team in seconds. You control the timing, the message, and the recipient list from your own application.

If you use call recording, the API lets you download recordings automatically and store them wherever your business needs them — your own archive, a compliance system, or any internal tool.

The same applies to call statistics. Instead of reading reports by email, you pull the raw data into your own dashboards and combine it with other business metrics. How many calls did each number handle? What is the average wait time in the queue this week? Which international number generates the most inbound calls? Your reporting tools answer these questions with live data from the API.

With a public API you typically spend weeks reading documentation, building prototypes, hitting limitations, and going back to the drawing board. Many integrations never make it past the testing phase because the API turns out not to support what you actually need.

With CallFactory’s private API the process is reversed. You describe your requirements, we confirm feasibility, and we deliver working endpoints. Your developer writes against endpoints that are guaranteed to do what was agreed. No surprises, no wasted development time. And because we build and maintain our own IVR platform, we can extend it for any use case without depending on a third party.

Depending on the complexity of the integration, a one-time setup fee and/or a monthly maintenance fee may apply. We discuss this upfront so there are no surprises.

If your integration grows and you need even more control, the natural next step is dedicated IVR servers — your own telephony infrastructure running exclusively for your business, with full API access and unlimited customisation.
