Important: Webhook security & IP allowlisting Webhook security relies on allowlisting Viva.com’s published source IP addresses at your server or firewall level. If your hosting environment, WAF, or security plugin blocks Viva.com’s outbound notifications, order statuses will not be updated and payments may appear stuck. Before going live, make sure your infrastructure allows inbound traffic from the IPs published by Viva.com. The current list and instructions are maintained at: developer.viva.com — Whitelist the Viva addresses This requirement is independent of the plugin — it applies at the server/firewall layer and must be configured by your hosting provider or system administrator. 1.1.0 – 2026-05-21 Add dynamic descriptor feature Logo update Optimize payment transaction handling Compatibility with woocommerce latest version Update viva.com sdk version Admin notices refactor Add notice prompting merchants to whitelist Viva.com IPs Conditional render notice on thank you page Minimum WooCommerce version raised to 9.2 — stores on WC < 9.2 must update WooCommerce before upgrading this plugin Minimum PHP version raised to 7.4 Security: credential fields (client ID, client secret) now masked in admin settings Security: REST webhook endpoint now validates EventTypeId and EventData before processing 1.0.2 – 2025-05-15 Add currency to transaction api calls 1.0.1 – 2025-03-27 Add brand color picker option for smart checkout Fix double request to viva during configuration 1.0.0 – 2025-02-05 Initial release.
