You can integrate TPV with Core SDK in below steps:

• ​Hash Calculation​

• ​Make payment​‌​

Hash Calculation

‌For TPV transaction, hash calculation formula is different from normal type of payment:

For multiple account number, account number should be pipe separated and max 4 account numbers are allowed.‌

Hash Formula:

// For single account number
beneficiarydetail = "{'beneficiaryAccountNumber':'123456789'}"
​
// For multiple account number
beneficiarydetail = "{'beneficiaryAccountNumber':'123456789|54321234|98765673|34767988'}"
​
// Hash calculation
Hash = sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||beneficiarydetail|SALT)
