Custom Programatic http request

[eagleboy]

is it possible to create custom http request programmatically
https://api.thingspeak.com/channels/xxxxxxxx/fields/4.json?end=[year]-[month]-[day] 00:00:00&results=1
for example 
[url=https://api.thingspeak.com/channels/1615881/fields/4.json?end=2022-01-21%2000:00:00&results=1][/url]
https://api.thingspeak.com/channels/1303...&results=1

Hello alperian,
