The examples can also be used to confirm if valid credentials are used in a custom code. For example, if a java or c# code returns 401, a quick WS API request using curl or a browser REST client may confirm if the issue is related to credentials or the code.
The article assumes that a user generated an API Key following steps outlined in CA Agile Central Application Manager documentation.
The article considers both APIKey and username/password authentication scenarios.
1. Use curl to see if you are able to reach Rally from the command line. Possible proxy issues or firewall issues.
I will post a curl using the APIkey and a curl using username/password. Please use whichever command is easiest for you. If you are using Windows and do not currently have curl installed, here is a link for curl: https://curl.haxx.se/download.html. It will be necessary to replace the example Workspace OID (<WORKSPACE_OID>) in the curl command to the workspace OID the application is using. Here is an article on how to find your workspace OID: https://ca-broadcom.wolkenservicedesk.com/external/article?articleId=47763
GET request with curl using ApiKey
Use ApiKey to set zsessionid as shown below. the "zsessionid:<API Key - include the underscore before the key>" will be replaced with the apikey being used in the application receiving the error:
curl --header "zsessionid:<API Key - include the underscore before the key>" -H "Content-Type: application/json" https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=workspace/<WORKSPACE_OID>
A GET request with curl using basic authentication (username:password)
curl -u <User>@<Company.com>:zsessionid:<API Key - include the underscore before the key>' -H "Content-Type: application/json" https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=workspace/<WORKSPACE_OID>
2. Ping Rally - run the following command in a command-line window on the machine that runs the app having the issue. Issues here may point to a DNS issue.
