This C# Package helps you easily interact with the vPos API Allowing merchants apps/services to request a payment from a client through his/her mobile phone number.

The service currently works for solutions listed below:

• EMIS GPO (Multicaixa Express)

Want to know more about how we are empowering merchants in Angola? See our website

• Simple interface
• Uniform plain old objects are returned by all official libraries, so you don't have to serialize/deserialize the JSON returned by our API.

Does interacting directly with our API service sound better to you? See our documentation on developer.vpos.ao

This C# library requires you set up the following environment variables on your machine before interacting with the API using this library:

Create an instance of Vpos (make sure to define the environment variables above to) to interact with our API. The constructor will be responsible for acquiring the tokens defined above to interact with the API.

Vpos merchant = new Vpos();

This endpoint retrieves all transactions.

TransactionsResponse transactionsResponse = merchant.GetTransactions();

Retrieves a transaction given a valid transaction ID.

TransactionResponse transactionResponse = merchant.GetTransaction("1jHXEbRTIbbwaoJ6w86");

Creates a new payment transaction given a valid mobile number associated with a MULTICAIXA account and a valid amount.

LocationResponse locationResponse = merchant.NewPayment("900111222", "123.45");

Given an existing parentTransactionId, request a refund.

LocationResponse locationResponse = merchant.NewRefund("1jHXEbRTIbbwaoJ6w86");

Poll the status of a transaction given a valid requestId.

Note: The requestId in this context is essentially the transactionId of an existing request.

BaseResponse response = merchant.GetRequest("1jHXEbRTIbbwaoJ6w86");
if (response.status == 200)
{
    RequestResponse requestResponse = (RequestResponse)response;
}
else if(response.status == 303)
{
    LocationResponse locationresponse = (LocationResponse)response;
}
