cic-ussd

A Fastify-based, USSD client implementation, that interfaces with the community inclusion currencies custodial system. It is built using Node.js (>=18). The app is designed to provide a simple and efficient way to create and manage USSD menus and interactions.

Pre-requisites

• Node.js >= 18
• NPM (Tested on v9.3.1)

Installation

1. Clone the repository:

git clone https://github.com/grassrootseconomics/cic-ussd

2. Change into the project directory:

cd cic-ussd

3. Install dependencies:

npm install

4. Create a .env file in the root directory of the project and add your environment variables:

cp .env.example .env

Running the app

To start the application in development mode, run:

npm run dev

To start the application in production mode, first build the application:

npm run build

Then start the application:

npm start

The application will be available at http://localhost:9000.

Usage

The app exposes an API for handling USSD requests. It currently supports the AfricasTalking USSD API. To use the API, send a POST request to the api/v1/ussd/africasTalking endpoint with the appropriate USSD payload. We recommend using the Dialoguss library for a more interactive and streamlined USSD experience.

Example request:

{
  "sessionId": "1234",
  "serviceCode": "*123#",
  "phoneNumber": "+254712345678",
  "text": "1*2*3"
}

The app will process the request and return a response in the format expected by USSD gateways. Example response:

CON Welcome to Sarafu Network!
1. English
2. Kiswahili

00.Exit
11. Next
