[Finix integration troubleshooting]: confirm your webhook endpoint URL is registered in the Finix dashboard and points at your store. Verify the webhook username, webhook password, and webhook signing key match the dashboard values exactly. Your store URL must be publicly reachable over HTTPS: Finix cannot deliver webhooks to YOUR_HOST or a private network. In sandbox, use Finix test cards (Visa 4895142232120006, MC 5200828282828210, Amex 370000000000002) to reproduce end to end.

Context: Stuck pending status usually means Finix webhooks are not reaching your server.
