Read Last Entry including Location in XML Format

When you include the offset parameter, ThingSpeak returns the time data with the specified offset from GMT. Append the first parameter after a question mark ?. This request returns the results in XML format.

Read Last Entry Including Status From a Private Channel in CSV Format

When you request the output in csv format, the file returned is a comma-separated variable format. Depending on your computer configuration, your browser can start additional software to display this format. Reading from a private channel requires the read API Key. Use the query string parameter api_key to specify the API Key. Each entry also has a status field. In this example, status=true returns the channel status entry for the last field along with the feed data. Append the second parameter after the ampersand &.
