Usage

Test project:

To understand and visualize how to use the library better, please consult our test project

Setting Up MoMo Environment

MoMo provides 2 environments for integration: development(dev) and production(prod). The model for environment is located at Environment. You can use the function selectEnv(String target, String process) to choose the appropriate environment setup for the processes you are calling.

Example configuration is provided in environment.properties in resources folder. By default, slf4j2 is used with Console and RollingFile Appenders. Please create your own configurations files for environment and log setup.

Integration

The library provides functions to conduct transactions through the All-In-One (AIO) Payment Gateway (com.mservice.allinone) and all other Payment (com.mservice.pay) options (App-In-App, POS, Dynamic QR Code)

For each payment options, you can choose to either use the provided code in Processors folder to immediately use MoMo services or extend from the models located in Models folder. To have a better sense of how the processors work, we recommend uncommented and run the code in PayGate and NonAIOPay
