ga:daysSinceLastSession >= 20

says. 400 : Invalid value 'ga:daysSinceLastSession >= 20' for filters parameter.

But according to the manual that's way you should do it. So what am I doing wrong here?

Answer 1

ga:daysSinceLastSession is a dimension. Dimensons can only be filtered on

• == Exact match
• != Does not match
• =@ Contains substring
• !@ Does not contain substring
• =~ Contains a match for the regular expression
• !~ Does not match regular expression !~

Answer: 'ga:daysSinceLastSession >= 20' is an invalid use of a filter because you cant do >= on a dimension.

Link to filters with the Core reporting api: Filteres

Edit: The only option I can think of would be a very scary filter something like ga:daysSinceLastSession==10,ga:daysSinceLastSession==11,ga:daysSinceLastSession==12

Note: I'm not sure how long a filter can be documentation says 128 characters for regular expression filters but I'm not sure if that limit will apply here. But the max length of a URL is 2000 characters so you will have to test the max length of your request string as you build it.

Answer 2

Data Type for daysSinceLastSession is String, so I guess a mathematical operator won't work (equality operator works fine in the query explorer). I think you'd have to go for an regular expression (at least two numbers, first numbers 2 or larger).
