# Native OTP




### Step 1.1. Substep


Native OTP is a feature, enabling merchants to accept a one-time password (OTP) on the app without redirecting users to a bank page. In addition, the OTP shall be auto-detected and auto-populated thereby improving conversion rates.

*User Experience for Native OTP Flow*






### Step 1.1. Key integration changes for integrating Native OTP via Hyper SDK


**Step 1 - Order creation** 

[Create Order](https://docs.juspay.in/ec-headless/android/base-sdk-integration/create-order-api) on Juspay Servers.

**Step 2 - Check card eligibility** 

Perform the Eligibility SDK call to verify eligibility of the card details entered by the user for Native OTP transactions. Refer Code Snippet on the right for more details.

* If the card is eligible, continue with Step 3
* If the card is not eligible for Native OTP, please perform a cardTxn for 3DS flow (i.e. without including Native OTP specific parameters)

**Step 3 - Initiate card transaction with Native OTP experience** 

If the card is eligible for Native OTP transactions, perform cardTxn SDK call, ensuring below additional parameters.

* authType :: OTP
* amount :: 100 (pass the amount to be displayed on the Native OTP screen)
* cardBin :: 552365 (pass the cardBin used for the transaction)
