Payer une facture / Recharger

Règle une facture (SenEau, Senelec) ou effectue une recharge prépayée (Woyofal). Le montant est débité du solde de votre compte (montant de la facture + vos frais de service FEE).

Le débit n’a lieu qu’après acceptation par le provider. En cas d’échec, aucun débit n’est effectué (ou un remboursement automatique est appliqué pour les recharges asynchrones).

Endpoint

POST /api/v1/billing/pay

Headers

Nom	Type	Requis	Description
Authorization	string	Oui	Bearer YOUR_API_KEY
Content-Type	string	Oui	application/json

Corps de la Requête

{
  "serviceCode": string,              // Code du biller
  "reference_client": string,         // Numéro de compteur / référence client
  "amount": number,                   // Requis pour Woyofal (montant libre)
  "reference_facture": string,        // Optionnel : facture ciblée
  "externalTransactionId": string,    // Optionnel : votre référence unique
  "callBackURL": string,              // Optionnel : URL de notification
  "customData": string                // Optionnel
}

Paramètres

Paramètre	Type	Requis	Description
serviceCode	string	Oui	`SENEAU_SN_BILL`, `SENELEC_SN_BILL` ou `WOYOFAL_SN_BILL`
reference_client	string	Oui	Numéro de compteur / police / référence client
amount	number	Woyofal	Montant à recharger. Requis pour Woyofal ; ignoré pour SenEau/Senelec (montant imposé par la facture)
reference_facture	string	Non	Cible une facture précise. Sinon, la 1ʳᵉ facture impayée est réglée
externalTransactionId	string	Non	Votre identifiant unique (idempotence)
callBackURL	string	Non	URL pour les notifications webhook
customData	string	Non	Donnée libre renvoyée dans le callback

Montant : pour SenEau et Senelec, le montant est imposé par la facture (le champ amount est ignoré). Pour Woyofal (recharge prépayée), le client choisit le montant via amount.

Réponse

Facture payée (SenEau / Senelec — synchrone)

{
  "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
  }
}

Recharge réussie (Woyofal — token immédiat)

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

token = code de recharge à saisir sur le compteur. Présent uniquement pour les recharges prépayées (Woyofal).

Recharge en cours (Woyofal — asynchrone)

Si le provider ne confirme pas immédiatement, la transaction passe en PROCESSING. Le token est livré dès résolution (consultable via le webhook / l’historique de transaction).

{
  "message": "Bill paid successfully",
  "transaction": {
    "success": true,
    "transactionId": "TID987654321",
    "transactionType": "BILL",
    "amount": 1000,
    "Status": "PROCESSING",
    "message": "Recharge en cours — token disponible sous peu"
  }
}

Pour une recharge PROCESSING qui échoue finalement, le montant débité (montant + frais) est automatiquement remboursé sur votre solde et un callback FAILED est envoyé.
