Run this command in your terminal to save the TDengine cloud token and URL as variables:

export TDENGINE_CLOUD_TOKEN="<token>"
export TDENGINE_CLOUD_URL="<url>"

Replace <token> and <url> with cloud token and URL. To obtain the value of cloud token and URL, please log in TDengine Cloud and click "Programming" on the left menu, then select "REST API".


The TDengine REST API is based on standard HTTP protocol and provides an easy way to access TDengine. As an example, the code below is to construct an HTTP request with the URL, the token and an SQL command and run it with the command line utility curl.

curl -L \
-d "select name, ntables, status from information_schema.ins_databases;" \
