Diagnoses Safaricom Daraja and M-Pesa API failures. Decodes errorCodes (400.002.02, 404.001.03, 500.001.1001, 500.003.02...), async ResultCodes (1, 17, 1032, 1037, 2001, 2028, 2040, 8006...), C2B and reversal codes, missing callbacks and sandbox/production mix-ups, with a lookup script and a step-by-step debug procedure. Use when an M-Pesa request fails, returns an unexpected code, or a payment or callback never shows up.
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
# Daraja troubleshooting
## Look up the code first
```bash
python scripts/explain_code.py 500.001.1001 2001
python scripts/explain_code.py --search "timestamp"
```
Synchronous errors look like `{"requestId": "…", "errorCode": "400.002.02", "errorMessage": "Bad Request - Invalid PhoneNumber"}`.
- Always log the `requestId`: Safaricom support needs it.
- `500.001.1001` covers several different errors; the **errorMessage** tells you which one.
The full code tables are in [reference.md](reference.md).
## Symptom → cause
| Symptom | Likely cause |
|---|---|
| STK "Wrong credentials" or invalid Timestamp | UTC used instead of EAT; the body Timestamp differs from the one in the Password; wrong passkey for the shortcode |
| STK `2028` on a Till | `BusinessShortCode` must be the store number and `PartyB` the Till; TransactionType must be `CustomerBuyGoodsOnline` |
| STK prompt never shows | Phone off or no signal, another session in progress (wait 1 minute), number not on Safaricom, AccountReference too long (`1025`) |
| Works in sandbox, fails in production | Sandbox key/passkey/certificate used live; product not on the production app; till/store mix-up |

How to install
mdr add mr-macharia/mpesa-daraja-skills-and-mcp/daraja-troubleshooting@sha256:c251415773318b75The 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.
