OpenAPI spec for API documentation?

Is there an OpenAPI spec for the API documentation, we are using the restfulcommunication sample.

When trying to authenticate to get a token. By sending the following, it returns a 404 error.

curl -X “POST” “https://video6.datasystems.com/API/IDP/connect/token” \
-H ‘Content-Type: application/x-www-form-urlencoded’ \
–data-urlencode “grant_type=password” \
–data-urlencode “client_id=GrantValidatorClient” \
–data-urlencode “username={username}” \
–data-urlencode “password={password}”

I have also tried the grant_type “windows_credentials” with basic auth, and that returns an “invalid_client” error.

What you describe appears to match the “getting started” scenario, which assumes that you’ve created a basic user in the Management Client and assigned that user to a role.

If you’re not using a basic user but instead a Windows AD user, I found an earlier post that might provide the best guidance: Get OAuth token through POSTMan. Keep in mind that a Windows AD user must also be assigned to a role in order to log in.
