Hi @KarenViviana,

Thank you for sharing with questions with the community.

Please refer to the library to learn how to build the request containing more than one variable. Then, you will have to modify the following command to include a data traffic rate that is greater than one variable.

    sprintf(command, "init#");
    sprintf(command, "%s%s/%s|%s|%s|", command, USER_AGENT, VERSION, METHOD, TOKEN);
    sprintf(command, "%s%s=>", command, DEVICE_LABEL);
    sprintf(command, "%s%s:%s", command, VARIABLE_LABEL, str_sensor1);
    sprintf(command, "%s|end#final", command);

All the best,
-Isabel
