Implements Safaricom M-Pesa Express (Lipa na M-Pesa Online / STK Push) and STK Push Query. Covers building the Password and EAT Timestamp, sending the PIN prompt to a customer's phone, handling the stkCallback, polling status, and acting on ResultCodes such as 1032, 1037 and 2001. Use for checkout or "pay now" flows where the business starts a payment the customer approves with their M-Pesa PIN.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# M-Pesa Express (STK Push)
## Flow
```
your backend --POST /mpesa/stkpush/v1/processrequest--> Daraja
<-- ResponseCode "0", MerchantRequestID, CheckoutRequestID (save as PENDING)
customer phone: PIN prompt (~60 s) → enter PIN | cancel | ignore
Daraja --POST stkCallback--> your CallBackURL (ResultCode 0 = paid)
no callback? --POST /mpesa/stkpushquery/v1/query--> final ResultCode
```
## Build the request
1. Get the Timestamp and Password: `python scripts/stk_password.py <shortcode> <passkey>` prints both. Put **both** in the body.
The formula is `Password = base64(BusinessShortCode + Passkey + Timestamp)`, with the Timestamp in EAT.
2. Fill in the body:
```json
{
"BusinessShortCode": "174379",
"Password": "<from script>",
"Timestamp": "<from script>",
"TransactionType": "CustomerPayBillOnline",
"Amount": 1,
"PartyA": "254712345678",
"PartyB": "174379",
"PhoneNumber": "254712345678",
"CallBackURL": "https://example.com/payments/stk/<secret-token>",
"AccountReference": "INV1042",
"TransactionDesc": "Order 1042"
}
```

How to install
mdr add mr-macharia/mpesa-daraja-skills-and-mcp/daraja-stk-push@sha256:0bfb1221f55ad5b2The line at the top of this page pins the label git:20261020.f2e8fad, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
