Cloud Terminal API problem

[hpeykov]

Hello,

I am developing a new program for my company to integrate a physical POS terminals from VIVA Wallet in our systems. I have configured demo account, physical POS device (Ciontek CS50 if that matters) connected to this account. Using the APIs from https://developer.vivawallet.com/apis-for-point-of-sale/card-terminals-devices/rest-api/eft-pos-api-documentation/ I can succesfully do all the things - request tokens, search for terminals, initiate sales (both payments and preauths), make refunds. We need to work with preauthorizations, I have requested and have needed access for that.

Unfortunately when I try to use https://demo-api.vivapayments.com/ecr/v1/transactions:preauth-completion API I receive error 404. Exactly the same happens if I send wrong entry (like transactions:preauth-completionXXX). Is it possible that the URL in documentation is wrong ? Or perhaps there is something else I am doing wrong ?

Thank you in advance for your answer.

P.S. I have asked the same question via online chat from the real account, sorry if this doubles it.

Sure. This was the request:

{ "sessionId": "25b60a42-b635-4881-9b88-2298e3b3b36e", "terminalId": "16004772", "cashRegisterId": "1", "amount": 195583, "currencyCode": "975", "merchantReference": "rs## ra#651416007#", "customerTrns": "RA#651416007\r\nTEST ", "preauth": true, "tipAmount": 0, "showTransactionResult": true, "showReceipt": true }

And after some pooling the session info is as follows:

{ "sessionId": "25b60a42-b635-4881-9b88-2298e3b3b36e", "terminalId": "16004772", "cashRegisterId": "1", "amount": 195583, "currencyCode": "975", "merchantReference": "rs## ra#651416007#", "customerTrns": "RA#651416007\r\nTEST ", "showReceipt": null, "showTransactionResult": null, "tipAmount": 0, "success": true, "eventId": 0, "authorizationId": "037933", "transactionId": "1c2787b2-9afa-47e5-826c-139b49d89960", "transactionTypeId": 1, "retrievalReferenceNumber": 411709037933, "panEntryMode": "07", "applicationLabel": "Visa Debit", "aid": "A0000000031010", "primaryAccountNumberMasked": "474503**4237", "transactionDateTime": "2024-04-26T09:41:55.303000Z", "abortOperation": false, "abortAckTime": null, "abortSuccess": false, "loyaltyInfo": null, "verificationMethod": "CONTACTLESS - ONLINE PIN", "tid": "16004772", "shortOrderCode": "4117124435", "installments": 0, "message": "Transaction successful", "preauth": true, "referenceNumber": 37933, "orderCode": "4117124435004772", "aadeTransactionId": "" }

Hello again,

Perhaps the changes to my demo account needed some time to apply, but today the situation is different. Now when I call https://demo-api.vivapayments.com/ecr/v1/transactions:preauth-completion I receive error code 200, as it should be, but unfortunately there is another problem - nothing happens on POS terminal device although I keep it with screen on. If I pool the session like https://demo-api.vivapayments.com/ecr/v1/sessions/dbe48a78-ff50-47ee-88d1-a86af925d16e it returns code 202 and following payload { "detail": "The session is being processed" }.

This continues more than three hours and still returns the same. I have installed webhooks, but they also are not called for this session.

I should also note, that if I do the procedure of capture (or cancel) preauthorization directly from the POS terminal it works as expected.

Thank you in advance for your help. Best regards, Hristo Peykov
