Payment engineering
Payment webhooks in WooCommerce: design for the second delivery
A practical guide to verified payment events, duplicate deliveries and safe recovery, with a checklist for testing a WooCommerce gateway.
A WooCommerce payment plugin in development, designed to bring Viva.com and Stripe payment options into a clear, consistent checkout.

VivaGo is being designed for stores in Greece and international markets, with Viva.com and Stripe. Availability will depend on the merchant’s country, provider account and payment method. The verified country and method matrix will be published with the tested release.
VivaGo is not available for purchase yet. Features and supported versions will be published with the tested release.
VivaGo is being designed so that licence expiry or a WideDock outage does not interrupt merchant payment processing.
We will publish the supported WordPress, WooCommerce and PHP versions alongside the checked VivaGo release. Checkout type, order storage and payment-provider requirements need their own acceptance criteria. A method appearing on a product roadmap does not mean it is available for every country, account or device.
Our requirement is that WideDock licence expiry, revocation or unavailability must not stop the merchant’s checkout, refunds, webhooks or reconciliation. Updates and support have a separate path. This is a development requirement, not a promise that provider or store outages can never affect a payment.
VivaGo is not available to buy or download today. There is no preorder or waiting-list form on this site. Prices, licence conditions, installation limits and support terms will be published before sales open. For now, the journal explains the questions we are working through and the contact page lets you discuss your store’s requirements.
