Is there a tag I can add to my url query that filters the output to specfic channels ID of a probe.

/api/table.json?content=channels&output=json&columns=name,lastvalue_&id=54907&

...this gives several channels number 1-6. I only wish to display channel ID 4.

Hi there,

you can use the "&count=1" option to limit the output. However, in this way you can only exclude channels which are at the end of the output.

Thank you Moritz!

Is it possible to format the PTRG JSON with HTML?

Hi callaghana,

You can change the output format of the API call:

"xml": default format (recommended)
"xmltable": a HTML table in XML format
"csvtable": comma separated format
"html": HTML table

More information can be found here

Thank you Moritz - I can't get xmltable to work. this and the other XML examples don't display data but trigger a XML file download but I need the data to be live.

Hi Callaghana,

Please note that this is the only way to use XML as output.

I might be going about this the wrong way. Do you know of a way to format ahtml page that sits on the the xml/json?
