Hi everyone, not sure if this is the right forum to post,
I've spent a lot of time on this topic and I must have missed something since I can't make any progress.
We plan on creating custom APIs for Business Central in order to replace our SOAP web services. I just tried to configure a simple custom items API to test but I just can't make the OAuth work.
I was able to configure the OAuth on a test SAAS base - it works just fine - but I'm blocked when trying on my on premise base.
I can generate a token but when I use it, I still obtain the "The credentials provided are incorrect" error message on Postman.
I followed this guide https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/automation-apis-using-s2s-authentication but it hasn't solved my problem. I tried different ways to connect my Business Central base to Azure but nothing seems to be doing the trick.
Here are my Postman parameters for reference : 
Is there something i'm doing wrong ?
