Is it any way to integrate one span sign with react-native platform?

Hi Sudalaimuthu,

I believe the "ability of the user to draw his signature Anywhere on pdf" refers to the "Capture" type signature where the user can draw his/her handdrawn during the signing ceremony - so you'd make sure when created the package, to set signature type as Capture. 

For the other question, there are two main directions you can follow and integrate a react native project to OneSpan Sign:
#1 To leverage the RESTful API

These documentations you may find useful when get started with OneSpan Sign APIs:

-Quick Start Guide: Create and Send a Transaction

-Interactive API page

-Sample Code: Node.js Web Form Application

And a potential workflow could look like:
step1: create and send a package from your backend (don't directly invoke OneSpan Sign API from react code)

step2: create a signer authentication token and build below link:
https://sandbox.esignlive.com/access?sessionToken={signerAuthToken}

step3: make sure your account has turned on New Signer Experience (it offers better cross-device experience)

step4: embed this link in an iFrame

step5(optional): fire Javascript Notifier and monitor events of interest during signing ceremony, for example "ESL:MESSAGE:STARTED:SIGNER_COMPLETE".

#2 To leverage the iOS and Android SDKs

Alternatively, OneSpan Sign also offers native iOS and Android SDKs.
