Connect 3CX to Hypamoon

Possible, with help from 3CX. The API is documented, but you cannot just create a key: access goes through 3CX first.

Possible

The check

Three questions about the API of 3CX, answered from its own docs.

Public API docs
Yes. Public guides for the Call Control API (REST and WebSocket) and the Configuration API. Read the docs
A key you create yourself
Yes. An admin adds a client application in the Admin Console under Integrations, API, and gets an API key. 3cx.com
Versions or a changelog
Not confirmed.
How it signs in
A client ID and API key from Integrations, API in the 3CX Admin Console, exchanged for a token.
Webhooks
Not confirmed.
Hosting
Cloud and self-hosted
Condition
Call Control needs a 3CX 8SC+ AI license.

What you can build

Start, transfer and log calls from your own CRM screen and get live call events through the 3CX Call Control API.

Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work

Good to know

  • 3CX signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for 3CX takes more work: ask your chat to check this first.
  • A self-hosted 3CX must be reachable over HTTPS from the internet; 3CX hosted instances already are.

Try it in your chat

First get access from 3CX. Then fill in what to read and write, and send it.

Say this in your chat

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

Say this in your chat

Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
