According to the TRKD API documentation the URL for street events service is:
Before calling this service we need to get an authentication token via
It seems a bit strange to call the token-service via httpS and then call the data service via http.
Street Events webservice is also available via httpS ... is it officially supported to call it at the httpS endpoint and on port 443? (works just fine)
In TRKD API tokenmanagement service is the only available via https due to the Client information like username and password etc.
Other Services are perfectly fine with the http or https calls.
but my recommendation to use https as that is likely to be more future proof and required in future apis.
https is more secure ... no-one can spy on the request/response
Still, "which is the best" depends on your point of view
