Connect the extension

Create a personal token in the web app and paste it into the extension, so your variants are saved for your team and no Claude API key is needed.

Up to date with v1.5.0Updated 26 October 20262 min read

A personal token links the extension to your account and to one workspace. Once connected, every variant you make is saved in the web app for your team, and you never need a Claude API key.

Create a token#

Open Connect the extension in the sidebar.

Connect the extension, with two active tokens.

If you need the full proxy address (the app address followed by /api/public/claude-proxy), it is under Full proxy address (optional) after you create a token.

Manage your tokens#

Active tokens lists every token that still works.

ColumnMeaning
NameThe name you gave the token.
WorkspaceThe workspace the token saves to.
Created onWhen the token was created.
Last usedThe last time the extension used it, or Never.

Create one token per computer, so you can revoke one without disconnecting the others.

Revoke a token#

  1. Find the token In Active tokens, find its row.
  2. Revoke it Select Revoke, then confirm with Revoke in the dialog.

The extension that uses it is disconnected at once. Revoking cannot be undone: create a new token to reconnect.

If a token is lost or exposed, revoke it straight away and create a new one. Henkan stores tokens only as a one-way fingerprint, so nobody can display a lost token again, not even Henkan.

Switch to your company workspace#

A token always saves to the workspace chosen when it was created. If your extension still saves to an older personal workspace:

  1. Create a new token Choose your company workspace as the Client workspace.
  2. Paste it in the extension Replace the old token in the Henkan Variant App tab.
  3. Revoke the old one Select Revoke on its row.

Connecting without a token#

The extension can also send requests straight to Anthropic with your own Anthropic API key. In that mode, nothing is saved in the web app and your team does not see your variants.

Use a personal token unless Henkan advises otherwise.
