mpesa-rust

About

An unofficial Rust wrapper around the Safaricom API for accessing M-Pesa services.

Notes

Warning! WIP, not recommended for use in production

Install

Cargo.toml

[dependencies]
mpesa = "0.2.5"

In your lib or binary crate:

use mpesa::Mpesa;

Usage

Creating a `Client`

You will first need to create an instance of the Mpesa instance (the client). You are required to provide a CLIENT_KEY and CLIENT_SECRET. Here is how you can get these credentials for the Safaricom sandbox environment. It's worth noting that these credentials are only valid in the sandbox environment. To go live and get production keys read the docs here``.

NOTE:

Only calling unwrap for demonstration purposes. Errors are handled appropriately in the lib via the MpesaError enum.

These are the following ways you can instantiate Mpesa:

use mpesa::{Mpesa, Environment};
use std::env;

let client = Mpesa::new(
      env::var("CLIENT_KEY")?,
      env::var("CLIENT_SECRET")?,
      Environment::Sandbox,
);

assert!(client.is_connected().unwrap())

Since the Environment enum implements FromStr, you can pass the name of the environment as a &str and call the parse() method to create an Environment type from the string slice:

use mpesa::Mpesa;
use std::env;

let client = Mpesa::new(
      env::var("CLIENT_KEY")?,
      env::var("CLIENT_SECRET")?,
      "sandbox".parse()?,
);
assert!(client.is_connected().unwrap())

If you intend to use in production, you will need to call a the set_initiator_password method from Mpesa after initially creating the client. Here you provide your initiator password, which overrides the default password used in sandbox "Safcom496!":

use mpesa::Mpesa;
use std::env;

let client = Mpesa::new(
      env::var("CLIENT_KEY")?,
      env::var("CLIENT_SECRET")?,
      "sandbox".parse()?,
).set_initiator_password("new_password");
assert!(client.is_connected().unwrap())

Services

The following services are currently available from the Mpesa client as methods that return builders:

let response = client
    .b2c("testapi496")
    .parties("600496", "254708374149")
    .urls("https://testdomain.com/err", "https://testdomain.com/res")
    .amount(1000)
    .send();
assert!(response.is_ok())

let response = client
    .b2b("testapi496")
    .parties("600496", "600000")
    .urls("https://testdomain.com/err", "https://testdomain.com/api")
    .account_ref("254708374149")
    .amount(1000)
    .send();
assert!(response.is_ok())

C2B Register

let response = client
    .c2b_register()
    .short_code("600496")
    .confirmation_url("https://testdomain.com/true")
    .validation_url("https://testdomain.com/valid")
    .send();
assert!(response.is_ok())

C2B Simulate


let response = client
    .c2b_simulate()
    .short_code("600496")
    .msisdn("254700000000")
    .amount(1000)
    .send();
assert!(response.is_ok())

Account Balance

let response = client
    .account_balance("testapi496")
    .urls("https://testdomain.com/err", "https://testdomain.com/ok")
    .party_a("600496")
    .send();
assert!(response.is_ok())

More will be added progressively, pull requests welcome
