A small API that does one job well.

# 1. Trade your credentials for a token
curl -X POST https://api.tranzaq.com/oauth/token \
  -d grant_type=client_credentials \
  -d client_id=tqz_test_… -d client_secret=…

# 2. Create a batch (safe to retry)
curl -X POST https://api.tranzaq.com/api/v1/payout-batches \
  -H "Authorization: Bearer $TOKEN" \
  -H "Idempotency-Key: payroll-2026-10" \
  -H "Content-Type: application/json" \
  -d '{ "name": "October salaries",
        "items": [{ "beneficiaryId": "…", "amount": 1850.00 }] }'
