Decode M-Pesa
Hash Numbers

What is HashBack?

When a payment is made to a Safaricom Till or Paybill, the M-Pesa callback contains a hashed MSISDN — an unreadable string representing the customer's phone number. HashBack decodes it into the real number in under 50ms.

• Pay-as-you-go — top up credits, pay per request
• 50ms average decode response time
• Safaricom & Airtel Kenya supported
• Credits never expire — use at your pace
• Simple REST API — POST /decode

curl -X POST https://api.hashback.co.ke/decode \
  -H 'API_KEY: {{your_api_key}}' \
  -d 'hash={{hashed_msisdn}}'

// Response:
{
  "ResultCode": "0",
  "MSISDN":     "254712345678"
}
