RE: Postman API connection fail

Thanks this helped and got it working, I had to ensure two things

1. key not copying correctly as mentioned by Suresh

2.License allocated to user . CSP login may not work but I'm not sure about this

Make sure you use the webservice access key and to copy the web service access key try to expand the page because by default when you copy it will not show the full key.

RE: Postman API connection fail

I just tried to connect to SaaS here, also on 17.5. At first I also couild not connect. I think since last time, both BC and Postman have had updates. But I got it to work. This is my URL:

api.businesscentral.dynamics.com/.../companies

And my connection details:

I know it does not help you that it works for me, but it should work. Please tripplecheck and try again. And also try the URL in a browser and see if that gives you different details.

OK good point about SaaS, then indeed you cannot enable NTLM. Do you know if the same connection used to work OK in the past / earlier builds?

I'm using BC SaaS so "Use NTLM Authentication" is not available or I don't know where to find :)

RE: Postman API connection fail

Hello,

I think it can have a lot of reasons. First of all, I know it is obvious but do check: In Postman that the request is set up for Basic. Or to inherit from parent and then the parent is set up for Basic. And the User Name is as it shows in the BC client, and then copy in the web service key:

I know that this is wha you say you do already, but sooo many times, problems in Postman is down to tripllechecking details.

Then see if the BC Service Tier is set up to allow "Use NTLM Authentication":

This tick oftem makes soap and odata connections start working.

If still no luck, then install Telerik Fiddler, and run a trace and see if that catches some more details.

Also looking forward to hearing from others if they have seen other reasons for this.
