Login error using sample ERP .net web service

edited Dec 2, 2019 3:12PM in SuiteCloud / Customization 1 comment

Hi, I downloaded and installed sample ERP web service (.Net) application and tried logging in to a sandbox account. However, I kept on getting the error below:

***SOAP FAULT: fault type=invalidCredentialsFault with code=USER_ERROR.Invalid application id: 100200.

Prior to this, I did the ff:

1. Enable Web Services feature.
2. Setup Web Services Preferences.
3. Download and install ERP web service .Net sample.
4. Configure the NSClient.exe.config file. For the login.acct, I used the value found in the Account ID textbox (Setup>Integration>Web Services Preferences) and I made sure that I have the Administrator role.
5. Run NSClientERP.exe

Howdy, Stranger!
