There are the following methods to ask CMX to do this translation bothall of which will be discussed below (or in a sub-page). The two methods are:
#Processing files through the running instance of CumulusMX
#Getting the value by using the local interface [[Cumulus_MX_Local_API#General_API_-_HTTP_GET|GET method]].
#Getting the values through the local interface [[Cumulus_MX_Local_API#General_API_-_HTTP_POST|POST method]]
 
The first method is used in files used as input for the Extra Web Files in CMX which are then processed by CMX if you tick ''process''. The output file then contains the value.<br/>
The second and third method's principal use is to be used programmatically from anywhere you can reach the CumulusMX machine.
 
'''NOTE''': it is not possible to give Webtag modifiers by using the getGET method, but it is in the POST method. Check out the differences in the above links.
 
There are three bonus methods for getting values out of the CMX database:
#Getting [[Cumulus_MX_Local_API#Predetermined_Data|predetermined data]] (not really with Webtags but useful in this context)
#Using MySQL through the Custom Upload feature
#Using the ''Custom Logs'' feature of CMX (from 3.22 and up) through which you get a timeseries of one or more Webtag(s)
 
== Processing files ==
The oldest, most common and possiblyprobably the easiest method for using webtags is processing a file (e.g. a HTML web page or a PHP script) which contains a webtag description like <#temp rc=y>. After processing the output file then contains the value (e.g. 17.1) for that webtag and the complete description, including the brackets have then disappeared.
 
The configuration should look like the screenshot below:
 
== MySQL ==
In the MySQL settings of the Interface there exists the possibility to create Custom Upload queries. This is n otnot the place to treat the use of MySQL extensively and the custom queries, but CumulusMX offers the possibility to use Webtags in such a Custom Upload query definition. The example below should clarify:
