Hi I'm currently working on an REST API integration, however, I can not seem to do this in OutSystems. The REST API call I make: A post with the following structure: header: content type: application / x-www-form-urlencoded; body: grant_type: client_credentials; Basic authentication completed (user and password). I am having the following error HTTP / 1.1 400 BadRequest Content-Type: application / json; charset = UTF-8 Pragma: no-cache Content-Length: 34 Cache-Control: no-cache Date: Tue, 09 Oct 2018 16:41:50 GMT Expires: -1 Server: Microsoft-IIS / 7.5 X-Powered-By: ASP.NET { "error": "unsupported_grant_type" }
Has anyone had this problem before?
Good night the problem was solved by passing the url in the form of a query String.
thank you

Hi Daianne,
I notice in write application / x-www-form-urlencoded rather than application/x-www-form-urlencoded (no spaces before and after the /). Not sure if that causes an issue, i think it should be passed on the call all without spaces.
Are you sure you need grant_type: client_credentials and not grant_type: password ?
Did you try to test your API using a program like Postman, and if does, it give the same error as your OutSystems implementation, or does it then work?
Regards,

Both Postman and OutSystems return the same error.
And did you try grant_type: password ?
If this is a rest API that you consume please check the documentation on how to use it and which grant_types are supported.
With the information you give it is not easy to understand why it shouldn't work.
