Code snippets

// Package : ^2.0.6 :   

new API({
      hostUrl: 'https://api.razorpay.com/v1/',
      ua: 'razorpay-node@' + Razorpay.VERSION,
      key_id: key_id,
      key_secret: key_secret,
      headers: headers
    });

// Package : ^2.9.2:   
    this.api = new API({
      hostUrl: 'https://api.razorpay.com',
      ua: 'razorpay-node@' + Razorpay.VERSION,
      key_id: key_id,
      key_secret: key_secret,
      headers: headers
    });

Node version

v18.13.0

Library version

^2.9.2

Additional Information

It is working in old package version (2.0.6) of Razorpay

I found API URL is different , may be its issue in API

https://api.razorpay.com/v1

but in new Updated package API is

https://api.razorpay.com

Start by reproducing customer creation with fail_existing set to 0 on Node.js package versions 2.0.6 and 2.9.2, comparing the API URLs shown in the issue. Check whether the changed base URL affects the duplicate-customer response, and confirm that the newer version returns the existing customer ID as expected.
