Objective

This document outlines the step-by-step process for companies to initiate and complete the HDFC Bank Connected Banking integration through the Open Money Platform, leveraging HDFC Bank’s secure API framework.


Step-by-Step Onboarding Process

Step 1: Initiate Request with HDFC Bank

  • Contact your HDFC Bank Relationship Manager (RM) and inform them of your intent to integrate with Open Money via HDFC Bank’s APIs.
  • The RM will coordinate the onboarding process with HDFC Bank’s internal teams to initiate setup.

Step 2: Register on HDFC Bank Developer Portal (UAT)

  • You will be directed to the HDFC Bank UAT Developer Portal for registration:

Step 3: Registration Approval

  • Follow up with your RM to ensure timely approval of the UAT registration.

Step 4: Access the Developer Portal

After registration approval:

  • Log in to the UAT Developer Portal using the credentials you created.
  • Enter your username, password, and OTP (sent to your registered mobile number) to access the portal.

Step 5: App Creation in Developer Portal

  • Generate a new SSL certificate.
  • Upload the leaf, intermediate, and root certificates during app creation.
  • Ensure all certificates are valid, correctly chained, and not expired.

Step 7: Bank Approval for App

  • After app creation, your request will go for approval with HDFC Bank’s internal team.

  • Private key associated with the SSL certificate

The Open Money team will configure these details in their backend and activate HDFC Connected Banking for your organization.
