Pong Chat developer docs

Everything you need to put Pong Chat on a site and connect it to your own systems.

Pong Chat has two halves you can program against:

In the browser — pong.js, a small loader that adds the chat to your page. You talk to it through one function, Pong(...): open or hide the chat, pass user data, listen to events.
On your server — a REST API to read clients and their messages and to send messages as an agent, and webhooks that post every new message to your endpoint, signed with HMAC-SHA256. Both are part of the Premium plan.

Keys

All keys are in the desk under Settings → API keys (admins only).

Key	Where it goes	Secret?
Public key	In the widget’s script address, `js.pong.ee/<key>`; the user part of REST auth	No — it is in your page source
REST secret	The password part of REST auth	Yes — server only
Identity secret	Signs verified user identity	Yes — server only
Webhook secret	Verifies the `X-Pong-Signature` header	Yes — server only

Secrets are shown once when you generate them. Regenerating one invalidates the old value immediately.

Host	What
`js.pong.ee`	The loader, at `js.pong.ee/<your key>` (older snippets: `call.pong.ee/pong.js`)
`chat.pong.ee`	The widget iframe and its WebSocket
`app.pong.ee`	The agent desk and the REST API (`/api/…`)
`files.pong.ee`	Uploaded files and images (unguessable URLs)
