Partner API — Start Here

The Fiatsend Partner API converts USDT or USDC into Ghana Cedis (GHS) and delivers funds to MTN Mobile Money, Telecel Cash, or AirtelTigo wallets.

Your system  →  POST /v1/withdrawals  →  FX conversion  →  Recipient MoMo wallet

Target: first sandbox payout in under an hour.

Quickstart (sandbox)

1. Health check

curl https://sandbox.fiatsend.com/v1/health \
  -H "Authorization: Bearer $FIATSEND_API_KEY"

2. Get a rate quote

curl "https://sandbox.fiatsend.com/v1/rates?from_currency=USDT&to_currency=GHS&amount=50" \
  -H "Authorization: Bearer $FIATSEND_API_KEY"

3. Create a payout

Use a unique reference_id per payout (idempotency).

curl -X POST https://sandbox.fiatsend.com/v1/withdrawals \
  -H "Authorization: Bearer $FIATSEND_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "amount": "50.00",
    "currency": "USDT",
    "recipient_phone": "+233501234567",
    "mobile_network": "MTN",
    "reference_id": "payout-001"
  }'

4. Track status

Poll GET /v1/withdrawals/{withdrawal_id} or register webhooks. In sandbox, status auto-progresses: pending → processing → completed (about 15 seconds).
