Initiate Payment

Once user selects one of the payment option and click on pay, Hit the Create Order API from your backend and get the token and merchant order id.

Call PhonePeKt.startTransaction to start the transaction flow.

import com.phonepe.intent.sdk.api.PhonePeInitException
import com.phonepe.intent.sdk.api.PhonePeKt
import com.phonepe.intent.sdk.api.models.transaction.TransactionRequest

try{
 PhonePeKt.startTransaction(
  activity = this,
   request = TransactionRequest(
   orderId = "DOC", // todo: get this from your backend
   token = "DOC", // todo: get this from your backend
   paymentMode = // more on this below
   ),
 requestCode = 725 // todo: pass your own request code
 that you would like to handle in onActivityResult
 method
 )
)
} 
catch(ex: PhonePeInitException){
 // Transaction could not be started.
 // either re-init the SDK and call startTransaction
 again
 // or use other ways to complete your transaction
}

paymentMode parameter can be of two different Types, you need to pass the correct payment mode based on the instrument selected by the user:

• If UPI Account is selected by user

import com.phonepe.intent.sdk.api.models.transaction.paymentMode.PpeIntentPaymentMode
import com.phonepe.intent.sdk.api.models.transaction.selectedOption.SelectedOption
 paymentMode = PpeIntentPaymentMode(
   selectedOption = SelectedOption.Account(accountId =
   "ACC_ID") //todo: send account id here
)

• If One Click pay/ Flash Pay is selected by user

import com.phonepe.intent.sdk.api.models.transaction.paymentMode.PpeIntentPaymentMode
import com.phonepe.intent.sdk.api.models.transaction.selectedOption.SelectedOption
 paymentMode = PpeIntentPaymentMode(
  selectedOption = SelectedOption.OneClickPay
 )

Get Payment completion result by overriding onActivityResult in your activity.

override fun onActivityResult(requestCode: Int,
resultCode: Int, data: Intent?) 
 {
  super.onActivityResult(requestCode, resultCode, data)
  when (requestCode) {
   725 -> { // todo: the request code that you passed to
  phonepe SDK
  // once you get callback from sdk, hit phonepe
  transaction status API
          }
      }
 }
