USDT invoices
Create a customer invoice through the v2 API and store its identifier with your order. USDT funding uses the TRON network. Confirm the required network before sending.
Wallet payments
Request payment from a WATADCASH wallet using the documented wallet-payments resource. This is separate from accepting Visa or Mastercard payments.
Confirm settlement
Verify the webhook signature against the exact raw body. Process each event once, confirm the resource, amount and currency, and acknowledge only after durable processing.
Business onboarding
Service activation and operating funds are separate. Available capabilities depend on the activated plan, key permissions and current account eligibility.
