In order to complete your integration for the Standard Checkout, you will need to develop code on your server as well as on the client-side. Nimbbl provides server side kits (PHP, .NET) and APIs and client-side SDKs to ease your development effort.

Client & Server Interaction

It is very important to understand the flow of the integration. There are certain steps that need to be carried out only on the server side and these need to be strictly followed to ensure your transactions are secure.

Client-server

  1. Your server makes a request with the order information to the Nimbbl server to create an order.
  2. Nimbbl servers will return an order_id as a part of the response.
  3. Pass the order_id and access_key from your server to your client, and launch the Nimbbl Standard Checkout from your client using the Nimbbl client-side SDK.
  4. Your customer can choose the desired payment method on the Standard Checkout and the Nimbbl client-side SDK will communicate with the Nimbbl servers to initiate the payment request.
  5. Nimbbl Server will respond to the payment request to the Nimbbl client-side SDK. The client-SDK will provide the response to your client system. This response will contain a nimbbl_signature that will need to be validated to check that the response has come from the Nimbbl server.
  6. Pass the response (including the nimbbl_signature received) from your client to your server. You will need to validate the signature on your server using the secret_key.

Integration Steps

The above steps are provided in detail in the following pages so you can build the perfect integration.

  1. Set up your Server - this will help you create the order
  2. Set up your Client - this will help you launch the checkout and receive the response
  3. Completing your Integration - this will help you handle the transaction status and all edge cases
  4. Test your Integration - this will help you get ready for Production
