If the customer is checking out as a guest, you can pass an alternative ID that helps track the payment session lifecycle. For example, this could be an Order ID or Cart ID. > **Warning** > This ID is associated with the customer. It plays a key role in ensuring consistency and maintaining connections across different systems. If you fail to pass the same x-routing-id for the same customer in all related API calls, it could lead to issues with API functionality. Therefore, it’s crucial that you use the same x-routing-id for all requests tied to the same customer. - Value: customer_1122 - Tags: String, Required ## Sample Code Snippets: ### Sample Request: #### Request Code Snippet: ```request curl -X POST https://api.juspay.in/v2/txns/txn_36dc6eada1d0463da91dc56c8262a8c3/authenticate/ch_xyz/resend \ -u your_api_key: \ -H 'x-routing-id: customer_1122' ``` ### Sample Response: #### Response: ```json { "gateway": "CYBERSOURCE", "payment": { "authentication": { "method": "GET", "url": "https://smartgateway.hdfcuat.bank.in/v2/txns/:txn_uuid/authenticate", "params": { "card_issuer_bank_name": "Axis Bank", "id": "txn_uuid", "fallback_url": "https://smartgateway.hdfcuat.bank.in/v2/pay/start/testhdfc1/moz3C1sYSVgAxme31pL?cardIssuerBankName%3DAxis%20Bank%26cardType%3DCREDIT%26paymentMethod%3DVISA%26paymentMethodType%3DCARD", "challenge_id": "ch_xyz", "resend_otp_allowed": true, "auth_type": "OTP", "submit_otp_allowed": true, "card_isin": "44**06", "card_brand": "VISA" } } }, "status": "PENDING_VBV", "id": "moz3C1sYSVgAxme31pL", "payment_info": { "card": { "extended_card_type": "CREDIT", "token_type": "ALT_ID", "tokens": [], "last_four_digits": "2986", "card_reference": "", "payment_account_reference": "V00100****0002347651786", "card_type": "CREDIT", "card_issuer": "Axis Bank", "expiry_month": "03", "card_fingerprint": "2j965k6pta***5ppvqnoeki", "saved_to_locker": false, "using_token": false, "using_saved_card": false, "name_on_card": "PRATHAMESH", "card_isin": "44***6", "expiry_year": "2027", "card_brand": "VISA", "card_issuer_country": "INDIA" }, "payment_method": "VISA", "payment_method_type": "CARD" }, "resp_message": "", "created": "2026-01-09T05:54:10Z", "resp_code": "", "order_id": "DOTP312312", "txn_id": "testhdfc1-DOTP1234-1" } ``` ## Path Parameters: #### id: Transaction Id - Value: Example:- txn_36dc6eada1d0463da91dc56c8262a8c3 - Tags: String, Mandatory #### challenge_id: Challenge Id - Value: Example:- ch_xyz - Tags: String, Mandatory ## API Responses: ### 200: #### order_id: - Description: OrderID for which the payment is being started. - Tags: String #### txn_id: - Description: Transaction ID for the payment attempt. - Tags: String #### status: - Description: Status of the transaction.
