Updated

Follow these steps:

  1. Request Dashboard access from your integration manager: send them the email address you want to use for the Dashboard.
  2. Create a widget in the Dashboard, set its Domain URL and note the Widget ID.
  3. Enter your Callback URL and set up the Secret Key for the widget URL signature. The Sign Key for verifying callbacks is generated automatically.
  4. Build the widget URL with the Widget ID, wallet address, your transaction ID and a signature (see https://widget.docs.mercuryo.io/guide/integration/security).
  5. Choose how to track status changes: callbacks, API polling or the Dashboard.
