Issue with URL encoding
You have to encode all whitespaces in you URL. So the URL should be /v4_6_release/apis/3.0/service/tickets?customFieldConditions=caption="Escalated%20To"%20AND%20value="Cloud%20Operations"
I have a query string that will return data successfully if I run it in Postman but if I pull the data via Python3 (http.client.HTTPSConnection), the target returns 'bad request'.
The problem:
/v4_6_release/apis/3.0/service/tickets?customFieldConditions=caption="Escalated To" AND value ="Cloud Operations"
I have tried putting +AND+ or %20and%20 or %20AND%20 instead of AND but no success. For example:
/v4_6_release/apis/3.0/service/tickets?customFieldConditions=caption="Escalated To"%20AND%20value="Cloud Operations"
^ This works fine in postman but returns <hr><p>HTTP Error 400. The request is badly formed.</p> when via Python3. 
Is there anything else wrong with the url encoding here?
