Write Data to Channel
Use the REST and MQTT APIs to update channels with software or devices
ThingSpeak™ is an IoT platform that uses channels to store data sent from apps or devices.
You can write data to your ThingSpeak channels in several ways: HTTP calls from the REST API, MQTT Publish method, and
the thingSpeakWrite
function from MATLAB. Learn more
about how to Choose Between REST API and MQTT API to update a
channel.
