[FEATURE]: [Iatapay] Use connector_response_reference_id as reference to merchant

[Sakilmostak]

📝 Feature Description

• Reference id are used to map transactions in the connector’s dashboard.
• Hyperswitch manages several reference ids, such as payment_id, attempt_id, and connector_transaction_id for a single transaction.
• However, merchants may encounter uncertainty when determining which ID to utilize in the connector dashboard to identify the payment.

🔨 Possible Implementation

• When we receive a response from the connector for the payment, we deserialize it and populate the response field in RouterData.
• For the TransactionResponse type, we must fill the connector_response_reference_id with a corresponding reference id for the merchant to identify the transaction.
• One might need to have exposure to api docs of the connector for which it is being implemented to decide what to fill in connector_response_reference_id.
• You can check this PR for further reference feat(connector): [Stripe, Adyen, Checkout] Add reference ID support for retries #1735

🔖 Note: All the changes needed should be contained within hyperswitch/crates/router/src/connector/

@SanchithHegde I am blank on this. Can you please help me with this as to how to proceed?

[AkshayaFoiger]

Hello @ALLENGJOSE ,
Thank you for getting in touch.
We would kindly recommend proceeding by configuring Hyperswitch on your local machine.

To give you a better idea on how to resolve this issue, I would like to elucidate how it has been handled in the context of Adyen. On examining the Adyen documentation regarding payment requests, it is evident that they accept a field known as reference within their API requests for creating a transaction. This reference serves as a means to specifically identify and reference individual payments, and thus, it can been aptly designated as a connector_response_reference_id. We have accordingly made the necessary modifications to the connector/adyen/transformer.rs file, to include reference field in payment responses. I recommend reviewing the details of these changes in this associated Pull Request.

We are hoping to do similar implementation for Iatapay.

I hope this information proves helpful. In case you have any further queries, you can ask them on this issue thread, or on our discord server, or on slack whichever you are comfortable with
