Pay a Bill / Top-up

Settles a bill (SenEau, Senelec) or performs a prepaid top-up (Woyofal). The amount is debited from your account balance (bill amount + your service FEE).

The debit only happens after the provider accepts the operation. On failure, no debit is applied (or an automatic refund is issued for asynchronous top-ups).

Endpoint

POST /api/v1/billing/pay

Headers

Name	Type	Required	Description
Authorization	string	Yes	Bearer YOUR_API_KEY
Content-Type	string	Yes	application/json

Request Body

{
  "serviceCode": string,              // Biller code
  "reference_client": string,         // Meter number / customer reference
  "amount": number,                   // Required for Woyofal (customer-chosen)
  "reference_facture": string,        // Optional: target a specific bill
  "externalTransactionId": string,    // Optional: your unique reference
  "callBackURL": string,              // Optional: notification URL
  "customData": string                // Optional
}

Parameters

Parameter	Type	Required	Description
serviceCode	string	Yes	`SENEAU_SN_BILL`, `SENELEC_SN_BILL` or `WOYOFAL_SN_BILL`
reference_client	string	Yes	Meter number / police / customer reference
amount	number	Woyofal	Top-up amount. Required for Woyofal; ignored for SenEau/Senelec (bill-imposed)
reference_facture	string	No	Target a specific bill. Otherwise the first unpaid bill is settled
externalTransactionId	string	No	Your unique identifier (idempotency)
callBackURL	string	No	Webhook notification URL
customData	string	No	Free data echoed back in the callback

Amount: for SenEau and Senelec the amount is imposed by the bill (amount is ignored). For Woyofal (prepaid top-up) the customer chooses the amount via amount.

Response

Bill paid (SenEau / Senelec — synchronous)

{
  "message": "Bill paid successfully",
  "transaction": {
    "success": true,
    "transactionId": "TID123456789",
    "externalTransactionId": "INV-001",
    "transactionType": "BILL",
    "amount": 104500,
    "transactionFee": 1045,
    "number": "210278816",
    "referenceFacture": "8000000680",
    "Status": "SUCCESS",
    "previousBalance": 500000,
    "currentBalance": 394455
  }
}

Top-up successful (Woyofal — immediate token)

{
  "message": "Bill paid successfully",
  "transaction": {
    "success": true,
    "transactionId": "TID987654321",
    "transactionType": "BILL",
    "amount": 1000,
    "transactionFee": 10,
    "number": "07061270877",
    "token": "1283930093209223",
    "Status": "SUCCESS",
    "currentBalance": 498990
  }
}

token = recharge code to enter on the meter. Present only for prepaid top-ups (Woyofal).

Top-up processing (Woyofal — asynchronous)

If the provider does not confirm immediately, the transaction goes to PROCESSING. The token is delivered once resolved (available via webhook / transaction history).

{
  "message": "Bill paid successfully",
  "transaction": {
    "success": true,
    "transactionId": "TID987654321",
    "transactionType": "BILL",
    "amount": 1000,
    "Status": "PROCESSING",
    "message": "Top-up in progress — token available shortly"
  }
}

For a PROCESSING top-up that ultimately fails, the debited amount (amount + fee) is automatically refunded to your balance and a FAILED callback is sent.

Error Response

{
  "message": "Failed to pay bill",
  "transaction": {
    "success": false,
    "Status": "FAILED",
    "message": "Insufficient balance"
  }
}

Error Codes

HTTP Code	Description
400	Invalid parameters, insufficient balance, bill already paid
401	Invalid API key
403	API under maintenance
409	externalTransactionId already used
