Hi! We had to migrate from Appian on cloud to on premise. Is it normal to successfully connect when using a Web API with a get (hello world) but not when using a post (upload a document)? On this case I've got a 403 - Forbidden error.

No - not normal.
I would guess it's a permission issue. Are you sure the service account was put in the right groups?
Yes, actually I duplicated what I did with the get method to be sure about that. I understand that it might happend for firewall issues or other permissions, but if that were the case, both the get and post methods should have fail.
I just realized that even though I added the service account on the web api, I didn´t added on the admin group of the application. I changed it and it worked. Thanks!
That makes totally sense as in Appian, a GET and a POST are two different web API objects which can differ in permissions.
