Request Body

Body

Field Name	Type	Description
userDetails	JSON Object	Custom fields associated with the user, supplied by the merchant. These fields are included in webhook notifications and other API responses for easy reference and tracking. An empty object can be sent.
merchantOrderId	string	Mandatory.A UUID used by the merchant to reference this instance or any transaction related to it.
callBackUrl	string	Mandatory.The URL to which payment status updates are sent.
amount	number	Mandatory. This is the amount the user wants to deposit in USDT or INR equivalent. If this field is empty user can enter the value in the payment flow.
currencySymbol	string	Mandatory. Supported Currency is "USDT" or "INR" only.
userEmail	string	Mandatory. The emailId of the end user.
isKYCNeeded	number	1 or 0. If set to 0 the user will not be required to complete KYC or provide KYC. If field is in passed, default behaviour is KYC is required. This bypass needs to be approved by the admin for the Merchant.
isUTRNeeded	number	1 or 0. If set to 1, the user will be required to provide the UTR (Unique Transaction Reference) number after making the payment. This is a recommended setting as it significantly reduces payment failures, disputes, and chargebacks while also enabling seamless processing through our automated Lightning Bridge.

Flow Modularity

1. KYC Bypass:

   • In certain use cases, KYC verification may not be required for the end user.

   • To bypass KYC, set isKYCNeeded to 0.

   • When enabled, the user will not be required to complete KYC, and any existing KYC records will not be checked.

   • Important: Merchants must have admin pre-authorisation to use the KYC bypass feature.

// Generate signature
const signature = createSignature(apiSecret, raw);

// Define headers
