C2B00014C2B / B2C resultM-Pesa error C2B00014: Invalid KYC Details (Reject)
This is a C2B / B2C result code — it applies to customer-to-business validation or business-to-customer disbursement flows.
What causes it
During C2B validation the payer's KYC details do not meet your requirements.
How to fix it
Return this reject code when KYC checks fail, otherwise accept the transaction.
How paylod handles this
