Hash Generation Logic

In completionBlockForHashGeneration, you will get hash string without salt so you need to append the salt at the end of this hash string and convert using sha512 and pass that value in hash completion as passing below in the code.

For more information, refer to Generate Static Hash.

Integration

  1. Set amount and userToken inside your payment parameters for instance
        paymentParamForPassing.amount = "amount"
        paymentParamForPassing.offerParams = PayUModelOfferParams()
        paymentParamForPassing.offerParams?.userToken = "Any default Value"
  1. Call the getAllOfferDetails() method to integrate this API as described in the following code block
 webServiceResponse?.getAllOfferDetails(paymentParamForPassing, completionBlockForHashGeneration: { json, hashcompletion in
                if let hashDict = json as? [String: String] {
                let hashName = hashDict["hashName"] ?? ""
                let hashStringWithoutSalt = hashDict["hashString"] ?? ""
                    let hashWithSalt = hashStringWithoutSalt.appending(kSalt)
                    let hash = hashWithSalt.sha512()
                    hashcompletion!([hashName : hash])
                }
            },
            completionBlockForAPIResponse: { [weak self] offerDetails, errorMsg, _ in
                print("offerDetails......\(offerDetails)")
            })
