Web API On Premise

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.

    That makes totally sense as in Appian, a GET and a POST are two different web API objects which can differ in permissions.
