Build a WooCommerce Plugin to communicate with our Payments API -- 2

Payments Gateway Plugin =================== Name ------ iZi Pasarela de Pagos Configuration Section ------------------------ The configuration section will be shared with other plugin we have for invoicing. Meaning that if both plugins are installed only one config section should be enabled. We will share this plugin so you can re-use the information, but it's basically 4 input fields (clientId, secret key, and 2 other numerical ids). In adition, the plugin should add this check to config page: (check) Crear Prefactura con cada checkout -> if this option is checked, the nit and razonSocial (these fields are added to the checkout page by the invoice plugin) should be sent when creating the payment request. Behavior -------- A payment method with name "iZi Pagos" and description "Paga con tarjetas de crédito/débito" should appear on checkout page. Once the buyer clicks on "Pay", a request should be sent to our server to create a payment. On the response of this call, you'll receive an id (to use later with invoice plugin) and a link, among other parameters. The buyer should be redirected to that link to make the payment. Once completed, the buyer will be rdirected back to the store. Integration ----------- The call to our API will send all the information needed to create a payment request. On the response, you'll receive a link to redirect the user. The call needs to be encrypted, we will provide with a working example in php.
