MTN Mobile Money API

This package provides for an easy way to connect to MTN MoMo API, it provides for the following products:

• Collection
• Disbursements
• Remittance
• Provisioning in case of sandbox environment

how to use:

use mtnmomo::Momo;
use uuid::Uuid;
use dotenv::dotenv;
use std::env;

#[tokio::main]
async fn main() {
dotenv().ok();
let mtn_url = env::var("MTN_URL").expect("MTN_COLLECTION_URL must be set"); // https://sandbox.momodeveloper.mtn.com
let primary_key = env::var("MTN_COLLECTION_PRIMARY_KEY").expect("PRIMARY_KEY must be set");
let secondary_key = env::var("MTN_COLLECTION_SECONDARY_KEY").expect("SECONDARY_KEY must be set");
let momo = Momo::new_with_provisioning(mtn_url, primary_key.clone()).await.unwrap();
let collection = momo.collection(primary_key, secondary_key);
}

After initializing the Momo struct, you can then use the collection, disbursement or remittance methods to initialize the respective products. The products have methods that you can use to interact with the API. For example, to request a payment from a customer, you can use the request_to_pay method of the Collection product.

important notes:

mtnmomo::Momo::new_with_provisioning is used to initialize the Momo struct with the sandbox environment. mtnmomo::Momo::new is used to initialize the Momo struct with the production environment.

example making a request to pay:

use mtnmomo::{Momo, Party, PartyIdType, Currency, RequestToPay};
use uuid::Uuid;
use dotenv::dotenv;
use std::env;

#[tokio::main]
async fn main() {
  dotenv().ok();
  let mtn_url = env::var("MTN_URL").expect("MTN_COLLECTION_URL must be set"); // https://sandbox.momodeveloper.mtn.com
  let primary_key = env::var("MTN_COLLECTION_PRIMARY_KEY").expect("PRIMARY_KEY must be set");
  let secondary_key = env::var("MTN_COLLECTION_SECONDARY_KEY").expect("SECONDARY_KEY must be set");
  let momo = Momo::new_with_provisioning(mtn_url, primary_key.clone()).await.unwrap();
  let collection = momo.collection(primary_key, secondary_key);

   let payer : Party = Party {
          party_id_type: PartyIdType::MSISDN,
         party_id: "234553".to_string(),
     };

  let request = RequestToPay::new("100".to_string(), Currency::EUR, payer, "test_payer_message".to_string(), "test_payee_note".to_string());
  let result = collection.request_to_pay(request).await;
}

The above code will request a payment of 100 EUR from the customer with the phone number "234553". The customer will receive a prompt on their phone to confirm the payment. If the customer confirms the payment, the payment will be processed and the customer will receive a confirmation message. If the customer declines the payment, the payment will not be processed and the customer will receive a message informing them that the payment was declined.
