Reproducing the Issue

Run the Integration center and observe the logs in the REST destination with HTTP 400.


Post recent preview release you observed the behavior of adding extra query parameters. These additional parameters got added as part of the query string. 

Additional query parameters in the url got generated due to a library upgrade which was done as part of a security initiative to make the application more secure.

In general the extra query parameters should be ignored by the REST endpoint while handling the incoming request.


This is not a bug and is expected behavior. Please ask the vendors responsible of the REST endpoint implementation to change the logic to ignore the query parameters (query strings).

The changes would be needed in the REST endpoint to ignore these additional parameters and process the request.
