Wrong URL ????

Wrong URL ????

hello,

I have built the interface to the "Calendar".

See attachment 1.

The updating of the token when the time has expired is also successfully implemented. (will be automated later in the query)

Only here I have a problem.
https://www.zoho.com/calendar/help/api/get-calendar-list.html

I have attached my PHP code once as a TXT attachment.
As well as its response as an image. Attachment 2:

"Invalid URL

Unable to process your request as the URL /calendar/api/v1/calendars?category=all&showhiddencal=true is invalid."


What am I doing wrong or is the documentation no longer correct?

Many thanks for your help.
