Hi, I tried to delete a channel data using POSTMAN as described here https://www.mathworks.com/help/thingspeak/clearchannel.html in Examples section: Use POSTMAN to Clear Channel The channel ID is correct, the write API key is correct, and the answer of postman after sending request is: { "status": "401", "error": { "error_code": "error_auth_required", "message": "Authorization Required", "details": "Please provide proper authentication details." } } I already tried to authorize me in Authorization tab using Basic Auth (username and password), but the result is the same. I already tried to use api_key in the request command directly: https://api.thingspeak.com/channels/1234567/feeds.json?api_key=XXXXXXXXXXXXXXXX The result is the same. 🙁 Does this channel deletion method work at all on ThingSpeak?

Hello everybody. Ich have built my own logging device for temperature and air-humidity. Everything worked fine. Now I moved the device to another room and I wanted to clear all the channel data. So I went into the channel settings and pressed the "Clear Channel"-Button. I was asked if I am sure and clicked OK. Then a message showed up telling me the channel is being cleared but unforzunately nothing happens. What am I doing wrong. Do you have any advice for me? Best wishes, Bernd
