Authentication Failed when send API to sandbox

prots — Fri, 01 Nov 2024 09:05:25 GMT

Hello,

I'm trying to check how the API works. I registered and try to send a request. So, I'm trying to send for example POST https://apitest.cybersource.com/pts/v2/payments

First I test API on the page https://developer.cybersource.com/api-reference-assets/index.html#payments_payments_process-a-payment_samplerequests-dropdown_simple-authorization-internet_liveconsole-tab-request-headers

1. Updated keys /credentials on the page
2. Sent the request using my account
Worked fine.

Then, I tried to do the same using Postman:
1. Copied headers from the page above
* hostapitest.cybersource.com
* signature keyid="30863dfc-54a2-49a3-***-7db45f770013", algorithm="HmacSHA256", headers="host v-c-date request-target * digest v-c-merchant-id", signature="Ed9XMG2GmfvhfFeel9II+jfdb2x6zBwOqUOx***89A="
* digest SHA-256=cwjLNSMNo0IFp7hbUtTNu+7KxaF9O67******nQ7J5g=
* v-c-merchant-id prots_****1730368156
* v-c-date Fri, 01 Nov 2024 07:07:59 GMT
* Content-Type application/json
2. Pasted into postman request (also I used the collection https://documenter.getpostman.com/view/2960117/S17m1riA provided by cybersource)
Got Result 'Authentication Failed'

As Alternative way, I wrote a simple .NET Console app and tried to send a request in the code (got from example https://github.com/CyberSource/cybersource-rest-samples-csharp/blob/master/Source/Samples/Authentication/StandAloneHttpSignature.cs )

The result is the same 'Authentication Failed'.

What am I doing wrong ? Is there any additional configuration required ?

I am working on integrating the SubscriptionsApi using .net core. Below is the example code.

I am using Sandbox - apitest.cybersource.com. I verified the date and it is following the standard described in the developer guide.

SubscriptionsApi instance = new SubscriptionsApi(clientConfig);
var subresponse = await instance.CreateSubscriptionAsync(requestObj);
if (response != null)
{
status = subresponse.SubscriptionInformation.Status;
}

Exception: CyberSource.Client.ApiException: 'Error calling CreateSubscription: {"response":{"rmsg":"Authentication Failed"}}'
