api calls to be made between EFT POS (card terminal) devices and ECR systems

[danielflorearadu]

Hi,

we have serious problems regarding EFT POS - our ERP.

the problems are different, either on a unique session-id we get a response like transaction failed, but in the viva portal as well as on the receipt it is successful,

either it appears to us that it is successful but in the portal it appears as having failed.

we don't use webhooks, we just initiate a sale and periodically query its status every few seconds: Initiate a Sales Request + Retrieve Session by Id.

we watch that Sales Request response is 200, Successful Response then we search for Retrieve Session by Id json for value success=true or false

Specifically, we have session id JzzoyGeg46, unique transaction 5e787e4c-5f51-4598-94bd-0cc0d2946c2d

And now if I query the status, it displays Transaction canceled by user

But in the Viva Portal the transaction is successful

another transaction

session id 16304888_11369 ... even now we receive succes = false, and in Viva portal is it with success.

Suma: 160.74
abortAckTime: null
abortOperation: false
abortSuccess: false
amount: 16074
authorizationId: null
cashRegisterId: "SH00001455"
message: "Invalid card"
orderCode: "0"
referenceNumber: 0
retrievalReferenceNumber: null
sessionId: "16304888_11369"
shortOrderCode: "0"
success: false
terminalId: "16304888"
tid: "16304888"
transactionDateTime: null
transactionId: null
transactionTypeId: null

once again, we rely on the fact that there is a unique session id, managed by us, to which we want an answer: success true/false

maybe the pos_ul automatically generates another transaction in addition to the first one
how do we know to identify it as being in conjunction with ours?

if we get success=true ... and yet it is false, how do we know to consider the transaction completed?

please, we are waiting for a solution from you. Maybe you have another logic of what should be interpreted in the answer, or regarding the uniqueness of the session_id, or another documentation. In the meantime we were waiting.

after 9 days I don't see any concrete steps from the Viva team.

I'm calling on colleagues and the forum, who have encountered these problems before - how was it solved?

when and how do you consider a transaction to be successful? the money was collected?

I found in the older topics only that the "success" parameter only indicates if a transaction is completed (when the value of success parameter is true) or failed (when the value of success parameter is false).

how and when do we consider the transaction to be completed? only through "message": "Transaction successful" ?

have you met, and if so how do you solve the cases where a failed transaction appears on a unique sessionid and still the money is collected?

we are talking about r EFT POS solution, which allows calls to be made between EFT POS (card terminal) devices and ECR systems.
what does webhooks have to do with this?

specifically, what exactly is taking so long? someone from you debug those unique session ids to see why I'm getting the wrong answer.

I really can't wait, we are talking about a production environment and almost 2 weeks have passed!!!

Hello @danielflorearadu,

Thank you for your additional information. Kindly note that via Transaction Payment Created Webhook and Transaction failed Webhook you will get notified about all the transactions that are completed or failed in your Viva Wallet account. We kindly suggest you use that solution until the issue is resolved.

what is the unique key to identify the transaction to which I receive an answer? between your webhook's and my sale made through ecr pos api (sessionID)?

[VivaWalletCustomerSupport]

Hello @danielflorearadu,

Thank you for your answer, you can check the "TransactionId" or "OrderCode" parameter to identify the transaction and match it with the "Retrieve Session by ID" response you are getting.

Kind regards,
