Scheduling sms sending via webservice

I am trying to schedule sms sending but its failing .It is sending the message right away.I would like it to wait until sceduled time.Below is the url i am writing to the browser.

i guess you have at least to escape spaces.

Even if i escape spaces .Its still sending right away

i have nearly no knowledge about json, but in anton’s exmaples space is written with ‘+’. maybe you can try schedule=2016-03-29+08:50:00

Thanks Andre .I tried you suggestion but the message is sending right away

can you provide logfiles?
