1. Payment Gateway Integration : Currently we have existing Razorpay Payment Gateway Integration. We want to add 1 more additional Integration with PayU/Stripe providing a configurable option to choose which gateway provider to be used. So scope to create APIs and Db level changes to cover : - Configuration to choose the payment gateway, and setup their secret keys - Modify our existing platform API to call specific Payment Gateway APIs for payment processing, refunds, cancellations etc. Primary scope of integration would be for Checkout Process Integration and it would cover Authentication, Invoking the Payment Gateway Providers Payment Page with the order value passed on when online payment option is invoked and showing success page / failure based on receipt of Payment Gateway API Success or Failure response. Refund Integration would cover Authentication, Invoking the Payment Gateway Refund API to pass on the Refund value and showing success page / failure based on based on receipt of Payment Gateway API Success or Failure response. 2. SMS Integration : We already have an existing SMS gateway providers API integrated. So we want to add one more additional gateway provider and the existing API has to be modified to call the optional provider based on input parameters. SMS integration would be invoked for Registration SignUp - OTP Verification and Password Resets. 3. Shipping/Logistics Gateway Integration - Shiprocket, Dunzo, Shadowfax, NimbusPost, XpressBee, Wefast, +1 more. Scope : 1. Create APIs and Database Structure to extend our Order Management process as currently we do not have 3rd party shipping integration 2. Configuration API to setup which Logistics Partner is selected by Seller and the Sellers Secret Key configuration storage of their account with the logistic provider 3. Integration - Authentication, Create/Update Order, Show Shipping Rates, Returns, Tracking, Fetch Labels/Manifest Database is on PostgreSQL and scope includes any table/query/indexation/optimized query. All API calls to DB will be using Stored Procedure Function Calls using PgPromise
