How will the Mpesa API Integrated WHMCS website look on the checkout process, payment and order processing.

Below is a step by step illustration of how the final Mpesa Integration solution will look like.

  1. Step 1: The customer will land on your WHMCS website, search for a domain name or hosting package, add to cart and proceed to make a payment. When making a payment, that is where the first instance of Lipa na Mpesa payment gateway will appear.

The customer will then be redirected to the Mpesa API in the background.

 Fig 2: The above is an illustration of how the customer will see the redirection happening.

 
The customer will finally end up on a page that displays a message on what exactly happened during the Mpesa API checks of the required integration variables like Phone, amount and the Daraja portal credentials.

 

 STK PUSH message after a successful stk push api request

 Fig 3: This screenshot shows the page the customer sees after successful request. The message is that the customer should check his or her Mpesa phone and enter Pin to complete the transaction.

 

On checking the Mpesa phone, there will be a popup message which is as a result of stk push Mpesa api integration (Mpesa Express API on Daraja).

Fig 4: shows the stk push pop up message as it will appear on clients phone. The client will simply enter Mpesa PIN to complete the transaction. As easy as that.

The next that the customer will see is the a successfully paid up WHMCS invoice. That means Mpesa API is updating Invoices automatically when a successful payment hits the merchant Paybill or Till Number.

Fig 5: Then Invoices will be marked as paid automatically and WHMCS system will detect it is paid and actually send a Payment Confirmation email to the customer registered email. This happens even if the customer hasn't reloaded the Order page or has not clicked the button to be redirected.

A nice idea in development is an auto-redirection to the customer invoices with a Payment successful page in consideration when payment hits the merchant account.
