# Create Invoice

> Create a payment invoice for energy delegation

## Create Invoice

Creates a payment invoice that generates a unique deposit address. When payment (TRX or USDT) is received, energy is automatically delegated to the target address.

**Useful for integrations where end-users pay directly** — no account balance needed.

### Request body

<ParamField body="address" type="string" required>
  Target TRON address to receive energy
</ParamField>

<ParamField body="energy_amount" type="number">
  Energy amount (32,000 – 5,000,000). Use this OR `transfer_count`.
</ParamField>

<ParamField body="transfer_count" type="number">
  Number of USDT transfers (1 – 100). Each transfer = 65,000 energy.
</ParamField>

<ParamField body="duration_hours" type="number" required>
  Rental duration (1 or 24 hours)
</ParamField>
