Hi, 
I am using ThingSpeak with Raspberry Pi Pico W, by using python langage. 
I am sending some pressure data from the raspberry with this method : 
request = urequests.post('http://api.thingspeak.com/update?api_key=' + THINGSPEAK_WRITE_API_KEY, json=dht_readings, headers=HTTP_HEADERS) 
And it works pretty good, i have fields with the new data every 15sec. 
But now i am trying send a CLEAR request by using the following method : 
url = 'http://api.thingspeak.com/channels/{}/fields/{}.json?api_key={}&days={}'.format(CHANNEL_ID, FIELD_NUMBER , THINGSPEAK_WRITE_API_KEY, NUM_DAYS ) 
clear_request = urequests.delete(url) 
Nothing to be done.
I also tried to clean or delete directly all info in the channel and not only the fields' data by this method : 
delete_url = 'https://api.thingspeak.com/channels/{}/feeds?api_key={}'.format(CHANNEL_ID,THINGSPEAK_WRITE_API_KEY)
clear_request = urequests.delete(delete_url)
 Still not working. 
I tired several ways, clearing the channel, deleting the channel, sending some empty update... none of them works. 
Clear Channel is working only from the website when clicking on the button, i would like to do it with a request.
So to make a little summary of what i am looking for : I want to automatically send a clear request from my microcontroller to thingspeak channel 1 each X times.
Is there any way to make it possible  ? 
Thank you for your answer. 
Sincerly Arthur
