This is an async rust library for accessing the mpesa apis.

To get an access token

``` rust use serde::{Serialize, Deserialize}; use base64::{Engine as , engine::generalpurpose};

[derive(Debug. Serialize, Deserialize)]

struct Response { accesstoken: String, expiresin: i32, }

[tokio::main]

async fn main() { let consumerkey = "Your consumer key here".tostring(); let consumersecret = "Your consumer secret".tostring(); let client = reqwest::Client::new(); let auth = format!("{}:{}", consumerkey, consumersecret); let auth = generalpurpose::URLSAFE.encode(auth); let body = client.get("mpesa token url here") .header("Authorization", format!("Basic {}", auth)) .send() .await .unwrap();

let bytes = body
    .bytes()
    .await
    .unwrap();

let response: Response = serde_json::from_slice(bytes.as_ref())
    .unwrap();

println!({:?}, response);

} ```

Making a request

An Example of a Mpesa Express (STK Push) request:

```rust let config = MpesaConfig::new().withaccesstoken();

/// Create a client to make requests with default config or you can provide your own check the docs for more info let client = Client::with_config(config);

/// all fields must be provided as strings let request = ExpressPushRequestArgs::default() .PartyA("") .PartyB("") .Amount("") .Password(shortcode, passkey, timestamp) .AccountReference("") .TransactionType("") .BusinessShortCode("") .CallbackURL("") .TransactionDesc("") .Timestamp("") .PhoneNumber("") .build() .unwrap();

let response = client ///the appropriate method is required for the respective api you are trying to access. .stkpush() .create(request) .await .unwrap();

println!("{:?}", response); ```

Methods to make requests to the mpesa api

To access different request use the following methods to access the apis mpesa provides. 1. Account Balance rust AccountBalanceRequestArgs::Default() 2. B2C rust B2CRequestArgs::Default() 3. Business Buy Goods rust BusinessBuyGoodsRequestArgs::Default() 4. Business PayBill rust BusinessPayBillRequestArgs::Default() 5. Mpesa Express Query rust ExpressQueryRequestArgs::Default() 6. QR code rust QRRequestArgs::Default() 7. Reverse Transaction rust ReversalRequestArgs::Default() 8. Mpesa Express (STK Push) rust ExpressPushRequestArgs::Default() 9. Transaction Status rust TransactionStatusRequestArgs::Default() 10. Tax Remit rust TaxRemitRequestArgs::Default()

This library still works for those targeting the wasm architecture.
