Get emi payment details for request
Use this endpoint to fetch the exact bank account details (bank name, address, account holder, IBAN, SWIFT), along with the amount, currency, and the orderId associated with the widget session. Partners call it right after receiving the iframe event (emi-payment-created) to obtain the bank requisites the customer must use for the transfer.  
Method and URL:
GET /v2/request/{requestId}/payment-details/emi- Sandbox: https://widget-api.sandbox.paybis.com/v2/request/{requestId}/payment-details/emi
- Returns “EMI payment details successfully retrieved” on 200 with the fields shown below.  
When to call: After your front end captures the orderId from the widget event and you have the corresponding requestId. The response data is the source of truth for the transfer and must later be echoed back in your webhook. 
What you get: orderId, amount, currency, and bankRequisites
These values are required to instruct the customer and to validate your POST /v2/webhook/emi later.
