Implements Safaricom Daraja B2C payouts from a business shortcode to customers' M-Pesa wallets (BusinessPayment, SalaryPayment, PromotionPayment) and to Pochi la Biashara (B2Pochi). Covers the initiator and SecurityCredential, OriginatorConversationID idempotency, Result and QueueTimeOut callbacks, and result codes 2001, 2040, 8006 and 21. Use for refunds, salaries, withdrawals, winnings, commissions or any business-to-person disbursement.
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
# B2C: Business to Customer
Money leaves your account, so **the outcome must be known before any retry.**
## Prerequisites
- A B2C (disbursement) shortcode with funds in its **utility account**. Top it up with `BusinessPayToBulk` (see `daraja-b2b`).
- An API operator (**initiator**) created in the M-Pesa org portal with the **ORG B2C API Initiator** role.
- A `SecurityCredential`: the initiator password encrypted with the environment's certificate (see `daraja-credentials-security`).
## Request
`POST /mpesa/b2c/v3/paymentrequest`. For Pochi la Biashara use `POST /mpesa/b2pochi/v1/paymentrequest` with `CommandID: BusinessPayToPochi`.

How to install
mdr add mr-macharia/mpesa-daraja-skills-and-mcp/daraja-b2c@sha256:5ae03406f8ffff89The 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.
