Simulate Customer-to-Business Payment

Format: 2547XXXXXXXX

The account number the customer is paying for. Max 20 characters.

How C2B Simulate works In production, a customer dials *150*00# and pays your shortcode (174379). In sandbox, this endpoint mimics that action — Daraja records the payment and fires a confirmation callback to your registered URL. A ResponseCode 0 confirms the simulation was accepted.
