Request Body

Name
Type
Description

merchant_id*

string

Merchant ID

transaction_monitoring_bypass

boolean

Optional flag to explicitly skip transaction monitoring rules.

data.transaction_amount*

string

Max Length=12 Allowed characters: 0-9 and .(dot) Note: this value always reflects the total dollar amount for example 1.00 and 1 both will be considered $1.00 and 0.10 will be 10 cents.

data.pre_settlement_fee_charge

string

An optional fee amount to be deducted from the transaction before settlement. This fee is processed at the processor level and reduces the net amount settled to the merchant. The value must be a positive number and cannot exceed the total transaction amount. Applicable in scenarios where the merchant needs to collect fees separately or adjust the settlement amount.

Constraints:

  • Must be a positive decimal number.

  • Cannot be greater than the transaction_amount.

  • If set to zero or omitted, no pre-settlement fee will be deducted.

Example:

  • Transaction Amount: $100.00

  • pre_settlement_fee_charge: $5.00

  • Net Settlement to Merchant: $95.00 (after deducting the $5.00 fee)

Note: The customer will still be charged the full transaction amount of $100.00, but the merchant will receive $95.00 due to the $5.00 pre-settlement fee deduction.

data.post_settlement_fee_charge

string

An optional fee amount to be deducted after the transaction has been settled at the processor level but before the net amount is paid out to the merchant. This fee adjusts the final payout to the merchant while maintaining the full transaction amount charged to the customer. Note:

  • Use this parameter for fees such as processing charges, administrative fees, or adjustments that need to be applied after settlement but before the payout to the merchant.

  • Applicable for scenarios where deductions are required post-transaction processing.

Constraints:

  • Must be a positive decimal number.

  • Cannot exceed the total transaction_amount.

  • If omitted or set to zero, no post-settlement fee will be deducted.

Example:

  • Transaction Amount: $100.00

  • Settlement Amount: $100.00 (full amount settled)

  • post_settlement_fee_charge: $7.50

  • Net Payout to Merchant: $92.50 (after deducting the $7.50 fee)

Note: The customer will still see a charge of $100.00 for the transaction. The deduction is applied only to the merchant's payout after the settlement.
