Callmaker API

With our API you can customise and integrate our dialer to achieve even more impressive results. Push in or update data. Retrieve data. Control and orchestrate. The possibilities are endless. You access the API with an OAuth 2 flow.

Send or update data with webhooks

Trigger on events

In an API-first system like Callmaker, built from microservices that communicate only through APIs and events, there are plenty of events to attach your webhooks to. We currently support the following events:

order: created / cancelled / confirmed / restored / unconfirmed

booking: created / cancelled / confirmed / edited / moved space / moved time / uncancelled / unconfirmed / accomplished / not accomplished / successful / not successful

number: created
number change: created

phonecall: started / ended

user: created / changed

Events

As soon as the event you’re listening for is triggered, the hook fires.

Auth

We support: OAuth Client Credentials, OAuth Password, Basic Auth, Explicit Header and No auth. You can also add a header to your OAuth flow for maximum security.

Requests

Update or send data using the methods: GET JSON / GET Raw / POST JSON / POST Raw / PUT / PATCH / DELETE

Data templates

Create data templates that pull in your fields and the system’s

JSON

Format your data as JSON and get automatic feedback on any syntax errors

Filter

By choosing which level or levels your hook connects to, you can easily filter what you want sent.

How do I authenticate with Callmaker’s API?

With an OAuth 2 flow.

Do we need a developer?

Not for Zapier – that’s set up in Zapier’s interface. The API is built for developers, but with the autopilots it’s possible to get integrations running without knowing how to code.
