Frequently Asked Questions

Will a user be asked to login once All-in-one SDK is invoked?

If the user is logged in on his Paytm App, then this flow will utilise user’s session of Paytm app i.e the device on which user is using merchant App.If user is not logged in on the Paytm App, then Paytm App login page will be invoked first. After login, All-in-One SDK will be invoked.

On iOS if user has a Paytm App on his device and is logged in, then Paytm App will get invoked. On android devices it will open as a half screen slider.

How to handle UPI based txns on All-in-One SDK?

UPI Journey will support the below UPI channels:

i. UPI Collect flow

ii. UPI Push flow i.e intent flow

iii. UPI Push express flow I.e users will be able to see their saved VPA (UPI Handles) that they maintain with Paytm which is~75 million VPA. This helps support faster checkout.

UPI Pin is accepted on this same flow avoiding the need to toggle between the Apps

By Mid April we will start supporting UPI Onboarding flow as well i.e if a user does not have a UPI Handle setup , we will allow user to setup a @paytm UPI Handle by fetching the list of his bank accounts and complete seamless onboarding

This flow also allows you to restrict the Payment method to UPI only as per your requirement and not show other payment methods

i. If you want to enable UPI as the only pay mode, then pass the below parameters within Initiate Transaction API "enablePaymentMode" : [ { "mode":"UPI", }]

UPI Intent capability is supported in Andriod device, OR if Paytm is opened in web view. It is NOT supported with IOS Operating system both in case of App /m-web

Is the UI customisable?

UI for All-in-One SDK is not customisable. Paytm App is getting invoked so experience cannot be customised.

If merchant integrates All in One SDK in the android app ,but the payment page/ cashier page is opened in web view . Will the All in One SDK be supported?

Yes, All-in-one SDK can be invoked from a merchant app web-view. Merchant can pass the control from m-web to his App using Javascript and then invoke All-in-one SDK. I have confirmed this.

If Paytm App is not available in a user device, then the user is redirected to web view. Would UPI intent be support in that case?

Yes, In case merchant is integrated with Paytm All in one SDK and the consumer does not have Paytm app, on redirection to web flow as well, UPI intent will be there.

Can All-in-One SDK be supported through m-web?

All in one SDK integration will be supported with merchants' Andriod and IOS app . Not with Mobile site.

Is Merchant Gift voucher (MGV) supported in All-in-One SDK?

Yes, All-in-One SDK supports MGV.

MGV is loyalty program for merchants via which customer buys merchant specific gift vouchers and they can pay to that merchant via that GV. Merchant Gift Vouchers will enable Paytm customers to transact seamlessly on the Paytm platform across merchants by purchasing these MGV for themselves.

If the user has a balance>0 for any merchant, MGV will be the first payment option shown to the user on the checkout page. In case of sufficient balance, MGV will be selected by default, and in case of insufficient balance, MGV will be greyed out to show the user any available balance in it. User will not be able to club MGV as a pay mode in Add and Pay, or Hybrid payment mode.

How will Paytm Assist work on All-in-One SDK?

Paytm Assist is already integrated within the All-in-One SDK. For Cards and NB transactions, when bank will send an OTP for verification, Paytm Assist will Auto-read that OTP and allow user to submit with one tap (or Auto Submit) on the screen.
