I often see a question in the community - "I use basic authentication with fresh Web Service Access Key to connect NAV API - and I'm getting unauthorized request, why?"
Here we will talk about on-premise installations (both - NAV2018 and BC)
To check your situation - Open your Administration environment and check Credentials type:
If it's "NavUserPassword" - everything should be ok. You need to take your Web Service Access Key (or generate if it doesn't exists) from user card:
And now you can test it with Postman for example:
But what if you see Windows credential type?
The only way I found - is to use NTLM authentication. Set this mark on the General tab:
And you also need to use it in Postman. And not with Web Access Key - you need your Password here:
