VISA API TWO-WAY SSL

[Sukakayaraznica]

Please, someone explain me, why I'm getting this response trying to check my connectivity to sandbox? I've check everythink by documantation tutorials several times. In postman certificates, I added certificate from credentials and my privatekey that was given me by visa when creating credentials, but everytime I get this response.
P.S. Also, trying to connect by java code, giving me connection timeout exception, what is the reason

Hi @Sukakayaraznica,

The error code "9123" usually occurs when Basic Authentication is not sent in the request header with username and password base64 encoded and ‘Basic ‘ prefix. Please double check that you entered username and password correctly.

Please follow the Two-Way SSL (Mutual Authentication) guide below:

https://developer.visa.com/pages/working-with-visa-apis/two-way-ssl#section4

If you continue to get this error, please provide us the correlation ID and we can further investigate the issue.

Below are the steps to get the Correlation ID using a Google Chrome browser.

1>Open Chrome menu.

2>Click on More tools then Developer tools.

3>Check the box to Preserve Log for the Network Tab.

4>Click on the error and go to the Headers.

5>You can find the Correlation ID in the network log.

I have exactly similar issue my corleation id is 1641963677_390_2135074239_l73c015_VDP_WS.

I have configured as it says in the document, but if run this in my corporate environment it is not working, if I try outside of the corporate environment it is working well. any reasons you think of?

Hi @JB1,

Your corporate environment might be blocking the domain name. If you're using VPN, you can try to disconnect from your VPN and then run the test. 

For Visa Inbound calls to our environments, we generally recommend the clients to whitelist the domain name. Here’s the domain names for the sandbox, certification and production environment. 
 
Sandbox environment - sandbox.api.visa.com
Certification environment - cert.api.visa.com
Production environment - api.visa.com

Please try that out and share your results with us.
