A coder is required to develop a WHCMS payment gateway which starts by verifying the client using Biometric API . Once the client has been verified another API checks the client's credit score. If credit score above a certain threshold then the client is automatically approved and their banking details are captured using an API. The client is directed to online DebitOrder Mandate where they sign and authorize capture of monthly payments. The client's invoice is queued for capture on the due date via the DebiCheck debit order API.
