Im following this documentation about report filters via URL: https://help.salesforce.com/articleView?id=reports_filter_url.htm&type=5
But treat this only as use case example. I want to clarify this in general terms.
In the link above, it says:
To see the order of filters in your report, refer to their order in the report builder. Alternatively, make a GET call to /services/data/v39.0/analytics/reports//describe and note their order in the JSON response.
Now I have tried to make the GET request directly via browser by pasting the given URL above and replacing the id placeholder with a valid report Id.
https://MYDOMAIN.my.salesforce.com/services/data/v39.0/analytics/reports/MY-VALID-ID/describe/
I only get
<Errors>
<Error>
<errorCode>INVALID_SESSION_ID</errorCode>
<message>Session expired or invalid</message>
</Error>
</Errors>
I have a good idea on how to make a "real" REST-call, but I would be interested if there might be some quick&dirty approach to get it via the browser?
