Manage sessions for frontend integration

There are two ways to provide a session ID when using the Delivery Gateway embedded UI:

• Use your merchant ID
• Pass the session ID from a backend service.

For a lightweight frontend integration, we recommend using the merchant ID: you pass it to the DGW instance and our Web Plugin will initalize the instance:

    const instance = DGW.mount({
        containerId: "delivery-gateway",
        merchantId: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
    });

Get the merchant ID from either:

• The Admin Dashboard.
• The Merchant API.

To make sure that only authorized entities can use your merchant ID to initialize Delivery Gateway sessions with the Web Plugin, set up allowed HTTP referrers: HTTP referrers for the embedded UI.
