Hi @Jan_Subrt ,
I understand you want to send data to a URL that will fetch the data in Make, right? If yes, if you already have the URL, you can make use of the HTTP module and have it use GET method to fetch the data that is sent to the URL. This data then can be parsed and used in any module or app that you wish to use.
Link to the documentation: https://www.make.com/en/help/tools/http
You need to use the Make a Request module of HTTP.
I hope this helps.
