How to test

Hi,

When we have the “Test mode” enabled, requesting the url https://www.domain.gr/wc-api/WC_em_Vivapayments_Gateway returns “-1”. However, when “test mode” is disabled, /wc-api/WC_em_Vivapayments_Gateway redirects to the homepage with /?msg at the end (i.e. https://www.domain.gr/?msg )

Is this the normal behaviour?

We have, latest WP, WooCommerce, and sef permalinks enabled.

Thanks in advance
