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?

Dear all, I have created an HTTP post with the corresponding REACT to send various measurement data of a bee hive to beep.nl. Unfortunately, the data does not arrive there although I was able to successfully transmit data with Postman which was then also written to the database (JSON an also with X-WWW-FORM). I can't explain what content error I have in the body? Unfortunately, my knowledge of MATHLAB is not sufficient to create a post from this. Thanks a lot in advance regards Peter -------------------------------------------------- Name:Beute 2 API Key:52G8X93X1UTSHH6K URL:https://api.beep.nl/api/sensors?key=kptnnz7wrz3qy90c HTTP Auth Username: HTTP Auth Password: Method:POST Content Type:application/json HTTP Version:1.1 Host:api.beep.nl Headers: Body:{"weight_kg"=%%channel_1293353_field_6%%, "h"=%%channel_1293353_field_3%%, "t"=%%channel_1293353_field_1%%, "p"=%%channel_1293353_field_4%%, "t"=%%channel_1293353_field_2%%, t_i=%%channel_1293353_field_5%%} Parse String: Created:2021-10-16 4:50 am --------------------------------------------------------

I have an Arduino project which collect sound data and send data to the ThingSpeak channel. I want to tweet with POSTMAN. When I click SEND button it works, however I have to create a regular tweeting function. For example, it should tweet the sound value every 2 hours. How can I do this, is there any KEY to complete this task?
