Overview

The signature generation process involves creating a unique cryptographic hash value based on payout parameters and your merchant private key to ensure data integrity and authenticity.

Process

Generate signature when you are creating a new payout.

Construct String: Concatenate the necessary parameters into a single string before applying the hash function. The parameters typically include:

Items	Description
order_id	Your internally created order_id
order_amount	The order_amount you passed for this payment
is_order_usd	The is_order_usd value you passed for this payment
token_id	Token ID you passed for this payment
receiver	Receiver wallet address
merchant_private	Your private key.

Apply Hash Function: Use a secure hashing algorithm such as SHA-256 to calculate the hash value of the before-hash string.
Pass the signature variable along with other parameters to the 'New Payout' endpoint.

//Request Body 
const payout = {
   //Your payout request body
};

//YOUR MERCHANT KEY
const merchantPrivate = process.env.PRIVATE_KEY;

//Concat payout parameters
const payload = payout.order_id + Number(payout.order_amount) + payout.is_order_usd + payout.token_id + payout.receiver + merchantPrivate;

// Generate SHA-256 hash of the JSON body
const signature = createHash('sha256').update(payload).digest('hex'); //hex digest

// Add signature to payout  object
payout.signature = signature;

//Perform Create new payout API call with payout object
