Hi. I am a developer based in Douala. I am working on a custom plugin that integrates with Mobile money and allows users to make payments on a woocommerce site. At first The payment method could not display on the checkout page until I stepped down the woocommerce version to 7.9.0. Now I am facing difficulties making payment requests with the plugin. That is the payment does not go through. I may not be passing values properly or communicating well with the sandbox of mobile money but I am lost. I have been at it for weeks and I really need assistance.
