After successful integration to your website, the following workflow occurs for a payment transaction

1. A customer creates an order in your online shop and clicks on checkout. This triggers E-nkap's POST /api/order endpoint to create an order with.
2. The customer will now choose the payment option that is best for him and submit. Just MTN Mobile Money, Smobilpay, Express Union Mobile and Orange Money are supported for now.

1. Based on the payment service provider, a feedback request may be necessary to confirm the transaction on the customer's side (e.g. MTN cashout confirmation via SMS or USSD).
2. Once the payment has been made, the status of the transaction will be changed to CONFIRMED or FAILED if it failed.
3. The status of the order can at any time be obtained by calling the endpoint GET /api/order.
4. If a notification URL is set in the merchant's API settings, changes in the transaction status will be sent to this URL.
