I am attempting to bulk write some JSON data to a ThingSpeak channel using the API. An example payload is: % Payload is data = { 'write_api_key': <my_api_write_key>, 'updates': [ {'field5': 833.205, 'field4': 6, 'field3': 775.648, 'field2': 24.2523, 'delta_t': 1, 'field1': 59.1391}, {'field5': 833.199, 'field4': 6, 'field3': 771.03, 'field2': 24.2844, 'delta_t': 2, 'field1': 59.1331}, {'field5': 833.208, 'field4': 6, 'field3': 750.343, 'field2': 24.3008, 'delta_t': 3, 'field1': 59.1405}, {'field5': 833.208, 'field4': 7, 'field3': None, 'field2': 24.2903, 'delta_t': 5, 'field1': 59.1479}, {'field5': 833.216, 'field4': 7, 'field3': 748.45, 'field2': 24.2965, 'delta_t': 6, 'field1': 59.1686}, {'field5': 833.21, 'field4': 8, 'field3': None, 'field2': 24.2914, 'delta_t': 7, 'field1': 59.1756}, {'field5': 833.204, 'field4': 8, 'field3': 738.847, 'field2': 24.2867, 'delta_t': 8, 'field1': 59.1943}, {'field5': 833.208, 'field4': 8, 'field3': 732.472, 'field2': 24.2814, 'delta_t': 10, 'field1': 59.1964}, {'field5': 833.212, 'field4': 8, 'field3': None, 'field2': 24.2599, 'delta_t': 11, 'field1': 59.1971}, {'field5': 833.207, 'field4': 8, 'field3': 737.475, 'field2': 24.2658, 'delta_t': 12, 'field1': 59.2122}, {'field5': 833.212, 'field4': 8, 'field3': None, 'field2': 24.2498, 'delta_t': 14, 'field1': 59.2161}, {'field5': 833.209, 'field4': 7, 'field3': 749.432, 'field2': 24.2503, 'delta_t': 15, 'field1': 59.2298}, {'field5': 833.208, 'field4': 7, 'field3': 760.224, 'field2': 24.2396, 'delta_t': 16, 'field1': 59.2308} ] } I am sending this payload programatically, in Python, with the requests library using the following command: response = requests.post(url='https://api.thingspeak.com/channels/<my_channel_id>/bulk_update.json', ... data=json.dumps(data)) This results in the response below: % Response { "status": "401", "error": { "error_code":"error_auth_required", "message":"Authorization Required", "details":"Please provide proper authentication details." } } I am certain that the API write key and channel_id are correct. I have used both for single writes successfully. I am using a free ThingSpeak account. I have also tried adding headers to the requests.post() call to indicate explicitly that this is json data. I'm not sure why this is occuring and would sincerely appreciate any pointers.

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?

I explain, under an alternative internet, I can send information without any problem from the Arduino to ThingSpeak, but when I connect to the network of my work (Ministry of Housing and Urbanization of Chile), it fails to send the applications, or I think it sends them but it is not able to receive answers .. In some occasions it does not solve the DNS, or in others, it resolves them, but it throws error 401 Unauthorized. So, I need to know what exactly the problem is, in order to send a ticket to those who are responsible for modifying the network here. To be more exact, I use an ENC28J60 module I would appreciate any help, if more information is missing just ask me, thank you and have a good day.
