Request Body

Field Name

Type

Description

isBuyTrade

number

Must be set to 1 for a Pay-In transaction.

userDetails

JSON Object

Custom fields associated with the user, supplied by the merchant. These fields are included in web-hook notifications and other API responses for easy reference and tracking. An empty object can be sent.

merchantOrderId

A UUID used by the merchant to reference this instance or any transaction related to it.

callBackUrl

string

The URL to which payment status updates are sent.

redirectUrl

string

The URL to redirect the user after completing the payment.

amount

number

Mandatory. This is the amount the user wants to deposit in USDT or BRL equivalent.

currencySymbol

string

Supported Currency is "USDT" or "BRL" only.

network

string

Only for Instant Channel: The network of the self-hosted wallet where the crypto will be settled. Accepted values: "ETH", "TRX", "AVAX", "TON", "SOL"

walletAddress

string

Only for Instant Channel: Please provide the public address of your self-hosted wallet where the crypto will be settled.

API Keys and Wallet / Network Configuration — Instant Channel Settlement: Please use the API Key associated with the designated wallet — PIX Instant Payin.

Before initiating settlements, kindly share the network and wallet address details in advance with the technical service team for whitelisting and template creation. This process typically takes 4–6 hours to complete. Network Fees & MDR — Instant Channel Settlement On Instant Settlement transactions, both MDR fees and network fees are automatically deducted from your PIX Instant Payin (Cross-Ramp) wallet balance, while the payment amount is transferred on-chain.

Example

If a payment of 165 BRL (≈ 30 USDT) is initiated:

On successful payment, 30 USDT is sent on-chain to the recipient.
The network fee (e.g., 1 USDT) and the MDR fee (e.g., 0.45 USDT) are debited from your wallet balance.
In this case, your wallet must hold enough balance to cover both the 1 USDT network fee and 0.45 USDT MDR fee at the time of creation.

Wallet Balance Requirement

A minimum balance of 50 USDT must be maintained in your PIX Instant Payin (Cross-Ramp) wallet to create a new payment link or transaction. Please ensure that the wallet remains sufficiently funded to cover on-chain gas costs and MDR fees, as these are deducted directly from your wallet balance for each transaction.
