Migration to latest Version V4

Migration from Version V3

If you're migrating from the last version i.e. 2022-09-01 (V3), following are the key changes made in this latest version 2023-08-01 (V4).

  1. Cashfree IDs type change [BREAKING]
    All cashfree IDs like cf_order_id, cf_payment_id, cf_refund_id etc are now in string format instead of integer (in older versions).

  2. Order Entity Changes

    1. We have removed payments, refunds, settlements urls from order entity.
    2. customer_uid part of customer_details in order entity. This is the unique identifier of the customer created at Cashfree. You can create customer at cashfree using Create Customer API
    3. order_status can have two more values - "TERMINATED" and "TERMINATION_REQUESTED". Find the complete list of order statuses here
  3. New Order Termination API
    We have released a new API to terminate an Order. Find API details - Order Termination API.

  4. New Customer APIs
    We have released Customer APIs to let merchants create and manager their customers. Find more about this here - Customer Management

  5. CF Refund IDs
    Earlier cfrefund_id used to start with a prefix "refund" . In this version, you will not get that prefix and cf_refund_id will be directly be the id without any prefix. Example - OLD cf_refund_id = "refund_41805719" , NEW cf_refund_id = "41805719"

Migration from Version V1 or V2

In the this latest version, we have revamped the integration method for using our pre-built checkout and made some changes in our SDKs.

Following are the key changes made in the latest version. Please check respective pages for detailed changes.

  1. Create Order API Change
    Deprecated use of order_token and payment_link from our APIs and instead introduced payment_session_id in response of Create Order APIs. Hence, you can not redirect the customer to the checkout page just by using the API. You'll need to use our JS SDK for starting checkout.
  2. New Javascript SDK
    Released new improvised JS SDK which will take in payment_session_id to redirect to checkout. This is a single SDK which can be used to either redirect the customer to checkout or render components check JS Component Integration.
  3. New Order Pay API
    New endpoint for order pay API is released. This will take payment_session_id as body parameter instead of order_token
  4. New SDKs
    Going forward, all SDKs will use payment_session_id instead of order_token to complete the payment.
  5. Whitelisting of domain name/package name
    All new integrations require whitelisting of domain or app package from where the checkout page is being opened. If you're using web integration, please whitelist your website domain name. If you're using a mobile app, please whitelist the app package name
    You can check step-by-step process of making whitelisting request here.
  6. Cashfree IDs type change
    All cashfree IDs like cf_order_id, cf_payment_id, cf_refund_id etc are now in string format instead of integer (in older versions).
