Set up Web SDK Channel

Back to SDK Embed a chat widget in your website with a single script tag. Web SDK is a deployment channel that connects a chat and voice widget on your site to a specific agent deployment.

Create a Web SDK Channel

The Web SDK channel connects a browser-based chat or voice widget to your agent. It supports two authentication modes — Anonymous / Public-key bootstrap for client-only apps, and Hosted token exchange for setups where a backend can hold a server secret.

Choose your authentication mode before you begin — it determines which additional fields apply later in this setup.

To configure a Web SDK channel, go to Deployments > Channels > SDK > Web SDK > + New and complete the following steps in order.

Set Up the Connection

On the New Web SDK Connection page, provide the following fields.

Field	Description
Display Name	A label for the connection (up to 255 characters).
Environment	The environment this channel follows; it tracks that environment’s active deployment.
Authentication	How customer browsers bootstrap SDK sessions. Select Anonymous / Public-key bootstrap or Hosted token exchange.

Choose an Authentication Mode

Mode	When to Use
Anonymous / Public-key bootstrap	Browser or client app. Store the public `pk_*` key, runtime endpoint, and channel selection in client-side configuration. No ABL secret is required, so you provision nothing extra on the customer server.
Hosted token exchange	Customer backend. The backend stores a reveal-once `sk_*` server secret and issues one-time `bootstrapToken` values; the browser stores only the short-lived token, runtime endpoint, and project ID.

If you select Hosted token exchange, complete the next step. Otherwise, skip to Select the Public SDK Key.

Set the Token Envelope Policy (Hosted Token Exchange Only)

The Token envelope policy controls whether Hosted Exchange SDK bootstrap and session credentials are signed or encrypted.

Option	Meaning
Use runtime default	Defers to the project-level default Hosted Exchange token envelope policy
Signed tokens	Issues signed bootstrap/session tokens only
Prefer encrypted tokens (`jwe_preferred`)	Uses encrypted (JWE) tokens when Runtime’s encryption capability is ready; falls back to signed tokens otherwise
Require encrypted tokens (`jwe_required`)	Requires encrypted issuance and verification end to end; fails closed rather than returning a signed token

Select the Public SDK Key and Create the Channel

Select the Public SDK Key the browser will use during SDK bootstrap, then select Create.

Configure Additional Settings

Once the channel is created, select it, then go to the Configuration tab to update the following fields:

Field	Description
Allowed Origins (CORS) (optional, both modes)	One URL per line, e.g. `https://example.com`, `https://*.example.com`. These origins are enforced for the public key linked to this SDK channel.
Server secret (Hosted token exchange only)	Studio generates the `sk_` server secret automatically on creation and reveals it once. Copy and store it in your customer backend immediately, since it cannot be viewed again. Server Secret Status, Server Secret Prefix, and Last Rotated* are shown afterward; use Rotate server secret to issue a new one — the previous secret stops working immediately.
Customer-issued encrypted bootstrap (Hosted token exchange only, toggle, off by default)	Accept customer-backend-issued JWE bootstrap tokens so sensitive and identity data can be encrypted before it reaches Runtime.

Configure Widget Behavior

Regardless of authentication mode, the same widget behavior settings apply, under Web SDK Settings.

Field	Description
Widget Mode	`Chat Only`, `Voice Only`, or `Chat + Voice`.
Features	Toggle Chat and Voice independently.
Show Agent Activity Updates	Off by default. Displays transient handoff, delegate, and reasoning activity for this SDK channel.
Theme	Choose a preset (for example `Light`) or select Add themes to tune the widget to match your host site.
Welcome Message	The first message shown to users, for example “Hello! How can I help you today?”

Save the Channel

Select Save Configuration, then Save Changes to apply the configuration.

Manage an Existing Channel

Opening a channel from Deployments > Channels > Web SDK shows four tabs: Overview, Configuration, Deployment, and Testing.

Overview
Configuration
Deployment
Testing

The Connection Summary shows these fields.

Field	Description
Status	for example: Active
Created	Timestamp the channel was created
Updated	Timestamp of the last change
Environment	for example: `dev`
Source Type	`SDK Channel`
Source ID	Unique channel identifier (UUID)

The tab collects these fields.

Field	Description
Agent Version	An Environment dropdown (for example: `Development`) that selects which deployed version handles incoming messages.
Active Deployment	Shows the bound deployment version and when it was deployed.

Select Save Changes after switching the environment/version.

Select + Generate Link under Secure Preview Link to create a secure, time-limited link to preview your widget. The link expires after 7 days.Copy the Embed Code the tab provides, for example:

    <!-- Agent SDK Widget -->
    <!-- Replace YOUR_PUBLIC_API_KEY with a full key that starts with pk_ca3b8ed5 -->
    <script src="https://agents-staging.kore.ai/api/sdk/embed/script" defer></script>
    <agent-widget
      project-id="PROJECT ID"
      api-key="YOUR_PUBLIC_API_KEY"
      endpoint="https://agents-staging.kore.ai"
      channel-id="CHANNEL ID"
      client-session-identifier="true"
      chat-enabled="true"
      voice-enabled="false"
      mode="chat"
      position="bottom-right"
    ></agent-widget>

Copy the above embed code.
Replace the API key placeholder with your actual key.
Paste the code before the closing </body> tag.
The widget will appear on your site automatically.

The embed code is generated per channel and already includes the correct project-id, endpoint, and channel-id for this connection — only the API key placeholder needs to be replaced.
