Integrate payment status with SMS alert with my existing system

I'm looking for a skilled developer to help me integrate the payment status with an SMS alert in my existing system. The platform to be used will be PHP, and I plan to use Paymongo as the payment gateway. The SMS alert should include both successful/failed transaction alerts, as well as transaction summary alerts. The system should be secure and efficient, to ensure all payments are accurately tracked and reported. If you have any questions about the project, please don't hesitate to contact me.
