How it works

Embedded wallets, page caching and environment selection need attention when the standalone plugin is first installed.

Implementation

Register iframe origins and review processor payment-domain requirements. Native panes can move a wallet to a top-level tab; sandboxed page-builder frames must allow that handoff. Test mode can still use live credentials if a sandbox set is missing. Compare installed plugin and API versions before upgrading. A successful browser return does not replace a signed payment result.
