MITA is issuing this CfT for the provision of an online payment processing service to continue providing a successful payment service to the Government, whilst complimenting the MITA Strategy 2021-2023. This online payment processing service shall be scalable, secure, open-standard d and flexible. MITA is requesting a holistic Online Payment Processing service which requires components that replicate the existing Government Payment Gateway (GPG) application programming interface (API) and eliminate the need for any infrastructure interface changes to existing merchant websites. MITA’s goal is that applications consuming the current service require no code changes to connect to the GPG service procured through this CFT.
