If the API responses seem to contain data that do not comply with the parameters used in the endpoint URL, you may try checking the following:
URL parameters are case sensitive
- All URL parameters you are using should be in lower case. For example, think of timespan vs Timespan - the API call would ignore Timespan due to the use of the capital T.
Timespan denotes duration
- The Timespan parameter represents time intervals, not dates or timestamps. For example, if you wanted to get responses for the last 10 minutes, you should use the timespan:10 parameter (provided that the subject API Service supports timespan in minutes - please check the Documentation page of the respective API Service for valid values).
