This repository contains example of using Monetha Payment Go SDK. Examples show main capabilities of SDK in order to achieve a decentralized payment via Monetha Payment Gateway

1. Make sure you have Git installed.
2. Install Go 1.12
3. Setup $GOPATH environment variable as described here.
4. Clone the repository:

   mkdir -p $GOPATH/src/github.com/monetha
   cd $GOPATH/src/github.com/monetha
   git clone [email protected]:monetha/payment-example.git
   cd payment-example

Note: You can skip steps 2-3 on Linux and use the official docker image for Go after step 4 to build the project:

docker run -it --rm \
  -v "$PWD":/go/src/github.com/monetha/payment-example \
  -w /go/src/github.com/monetha/payment-example \
  golang:1.12 \
  /bin/bash

Install dependencies:

make dependencies

After dependencies are installed you can start the examples

All examples are run with Test Customer and Merchant addresses. We've provided private keys to those address for simplicity of onboarding and showing how SDK works. We call everyone who are executing examples not to withdraw Ether funds from those addresses.

We are using Infura.io JSON RPC in the provided examples in order to execute transaction on a chain. Feel free to change backendURL variable to any JSON RPC node you want.

backendURL := "https://ropsten.infura.io/v3/7c0fc2888a824c62a3651fd446c8f989"

Note: Currently all PaymentProcessor contract instances are provided by Monetha. Contact [email protected] in case if you would like to have your own instance deployed.
