Issue:
When testing an API from API Explorer it is noticed that an additional query parameter is being added to the URI
ie:

https://gateway_host/v1/api?_=1525626141103 

 
Environment:
CA Developer Portal 4.2
 
Resolution:
The timestamp being added is a common practice to avoid the caching issue when communicating to the server. This is done to provide a unique URL to the browser so it will fetch a new copy from the server rather than retrieve from cache. This should not cause issues with the API.

If for some reason this does cause a problem you can use a simple regular expression to remove the offending parameter. Ultimately though the API should be reviewed to determine why it cannot handle this value.
