I have a small project in my university. I have created channel and it is collecting data from my sensor with rate of 1 data point/minute. I want my public user to access my data for one day data collection which is around 1440 datapoints. The current setup only allow the public user to get 100 datapoints only. Is it possible for the public user to get more datapoints from my channel? If it is possible, could you please tell me the detail procedure. Thank you

Hi @Regidestyoko
You can use thingSpeakRead function in matlab or by making HTTP GET requests to the ThingSpeak API. By default, the maximum number of datapoints returned in a single request is 8000. To retrieve more than 100 datapoints, you can use pagination to make multiple requests and concatenate the results.

Also here is the API call for read data documentation.
use the parameters for results or days or minutes, daterange to control the number of points returned.
For thingSpeakRead, use numdays, numminutes, numpoints, etc.
Appreciate the answer @Anuj. We are always looking for more knowledgeable community participants on the thingSpeak forum, please visit sometime if you can.
