Thingspeak, Delete channel with HTTP DELETE, webwrite

Hey there,

I want to delete a thingspeak channel using the webwrite function. This is what it looks like:

url = ['https://api.thingspeak.com/channels/' channelID '.json']
options = weboptions('RequestMethod','delete', 'MediaType','application/x-www-form-urlencoded');
response = webwrite(url,'api_key',userAPIkey,options)

This returns status 401 Unauthorized. But if I only change the RequestMethod to 'put', I don't get any errors. But using 'put' only allows me to change the channel settings. How do I delete the channel using webwrite?

Make the api_key a querry string parameter.

url = ['https://api.thingspeak.com/channels/' channelID '.json?api_key=<userAPIKey>']

options = weboptions('RequestMethod','delete');

response = webwrite(url);

Still returning status 401

HELP!! D:

My code:

channelID = "..."
userAPIkey = "..."
url = ['https://api.thingspeak.com/channels/' channelID '.json?api_key=<userAPIkey>']
options = weboptions('RequestMethod','delete', 'MediaType','application/x-www-form-urlencoded');
response = webwrite(url,'api_key',userAPIkey,options)

I was just using this code and I think this is more robust. I got extra characters when I used the above.

url = sprintf('https://dev1-web.thingspeak.com/channels/%d.json?api_key=%s',channelID,userAPI);
options = weboptions('RequestMethod','delete', 'MediaType','application/x-www-form-urlencoded');
response = webwrite(url,options)

but make sure channelID is a number, not a string. (no quotes)
