Posted on by Community Member

Hi,

I am using the username and web service access key for authenticate in the postman but i was getting the 401 error.

I also tried both the authentication type i.e Basic and NTLM.

Could you please help me how to try this in postman because it worked for me in chrome fine but in postman it's not working.

Thanks,

Vaibhav

    It depends on which Credential Type you are using on your NAV Service , if you are using NavUserPassword Authentication, you need to use Basic authentication , with format Basic username:password ( where password is the web service key and username:password need to be  in Base64 Encode) .

    If your NAV Service using Windows Authentication , you need to use NTLM authentication  , where username is your Windows Login username and password is your Windows Login Password
