Put Dium inside your product. Keep your members on your site.

Call the partner API from your backend, mount Dium under your own domain, and sign members in with a one-time token.

Read the quickstartGet an API key

No SDK to install. Every call is a JSON POST you can make with curl.

What you can build on Dium today

Five real building blocks. We only list what runs in production now.

Partner API

Create Flows, seed sessions and add sponsor pages from your own backend. Plain JSON over HTTPS, one key per partner, scoped by action.

API reference

Mount Dium in your own site

A small PHP file on your server puts the full Dium app under a path you choose, such as /community/. Members never leave your domain.

Mount guide

Signed autologin

Your server asks Dium for a one-time token that lasts five minutes. The browser swaps it for a session. No second password.

SSO guide

Identity through Moat

Every member has one Moat public key. Names and avatars come from Moat and stay in sync across sites.

How identity works

Real-time rooms

The mounted app gets live replies, DMs and session updates through Echo rooms, with polling as a backup.

What exists today

One surface can sit in an iframe: the member map

The rest of the app refuses to be framed on purpose. The member map is the exception, and only for origins we have allowed.

From zero to a signed-in member in three calls

  1. Get a partner key

    We issue keys by hand for now. You tell us your site, your mount path and the actions you need. We add them to our partner registry.

  2. Make your first call

    From your server, POST to /api/auth.php with action: "issue_token" and a member's email. You get a one-time token back.

  3. Send the member in

    Redirect the browser to /home/autologin.php?token=.... Dium checks the token, sets the session and opens the Flow.

How to get an API key

There is no self-serve key page yet. The Dium team issues each partner key by hand and sets its scopes with you.

Write to us with the details on the right. We reply with your key, the mount template and a config sample. Ask us to send the key through a password manager or secret-sharing link, not plain email.

What to send us

  • Your company and a technical contact
  • The origin your server calls from, for example https://acme.com
  • The path where Dium should live, for example /learning/dium/
  • The actions you need, such as auth.issue_token or exhibit.create
  • The Flow or event IDs you will manage (your external_id values)

What we set up on our side

  • Your key and its scopes in our partner registry
  • Your origin on our CORS allowlist
  • Your host on our redirect allowlist
  • The mount template and config sample for your server
