nativecheckout/v2/transactions using preauth fails with 502

[Stratubas]

Hello!

In the "demo" environment using Postman, nativecheckout/v2/transactions works (returns an object containing a "transactionId") only if "preauth" is set to "false" in the request.

Setting "preauth" to "true" returns the following:

{
    "status": 502,
    "message": "Transaction failed",
    "eventId": "10051"
}

In the documentation (https://developer.vivawallet.com/online-checkouts/native-checkout-v2/#create-transaction) there are no explicit instructions on requesting a pre-auth. I assumed the only difference is setting "preauth" to "true". Is that wrong? Or is a problem from your side? If so, can we expect it to be fixed soon?

Thanks in advance

I was using these instructions (https://developer.vivawallet.com/api-reference-guide/payment-api/card-tokenization/#step-1-generate-charge-token-using-card-details) to create charge tokens.

After following these instructions instead (https://developer.vivawallet.com/online-checkouts/native-checkout-v2/#create-a-charge-token) and requesting a "preauth", the "SALES TRANSACTIONS" page in the demo environment dashboard crashes:

Unfortunately there are known issues with the demo environment that occur intermittently. Please try again from the beginning of the process and let me know if the problem recurrs.

@matthewrgourd The steps seem to be working. However, the v2 charge token generation requires a specified "amount". What is that amount? Is it somehow related to preauth? The nativecheckout/v2/transactions request works even if its "amount" is greater than that specified during charge token generation. With https://demo.vivapayments.com/selfcare/el/sales/mysales crashing it's not easy to see what really happens.

I have the exact same issue with preauth in the demo environment, everything works fine when I set it to false, but when it's set to true, I get the error @Stratubas mentions above.

{ "status": 502, "message": "Transaction failed", "eventId": "10051" }

Are there any news regarding its fix? Thanks for your time.
