could be possible that some developer helps me to put the correct URL in the webhooks on my sandbox and woocommerce, please?
Hello @Pikywines,
You can configure the webhook URL linked to your sandbox account directly in your sandbox dashboard settings page.

For the Woocommerce part we invite you to contact the developers of the plugin directly.
Let us know if you have any question.
