Does weblog expert have support for API, one example is that we would like to export (dashboard only) with giving time range as pdf/csv and somehow automate this?
The program doesn't support API, but it allows you to use command line to analyze profiles and allows you to specify some parameters (e.g. time range) here. However, there is an issue with such analysis - if custom parameters are specified here, the program reanalyzes all data for this profile/time range before creating a report, it cannot just extract data from the analysis database. So if you have large amounts of data, such function probably won't be helpful.
