About the Data Extraction API
The Data Extraction API enables you to retrieve Webtrends Analytics 9 profile and report data, and monitor key metrics for profiles. The Data Extraction API conforms to the REST (Representational State Transfer) architectural style, using the HTTP protocol and a URI to access resources.
- Integrates with Excel without coding, client software, or installed driver--you need only your Webtrends credentials to get data
- Returns the entire data set for a trend in response to a single URI (for example, trending a month by days)
- Is profile and account independent, so you can list multiple profiles by changing the profile name in the URI
- Provides macros that enable you to request data for “yesterday” or “this month”
- Enables creation of AJAX applications (or any other web interface for Webtrends data)
- Caches data for better performance
Data Extraction API vs. Analytics User Interface
The Data Extraction API exchanges and transfers stored data only, so the report data from it will not always match the data seen at the Analytics user interface, because some reports in Webtrends Analytics 9 may contain numbers resulting from rounding, limiting decimals, or averaging subtotals. Data Extraction API report data does not include averages (unless they are a measure of actual analyzed data - see Note below), subtotals or other values sometimes shown in the Analytics user interface, specifically:
- Averages and percentages for measures in drill-down reports -- these are shown in the user interface so measures are not blank when the drill-down is collapsed. These are excluded from Data Extraction API responses.
- Sortable "Measures" column -- this contains a calculation designated as an average that is not valid for comparison. This measure average is not equivalent to the actual measure (which may itself be designated as an average, for example, "Average Visits").
Note: An example of an average that is actual analyzed data returned by the Data Extraction API is a customer-created measure called “Average RSS Feed Subscriptions”. It is based on a parameter, and stored in the report table, as opposed to derived at display time.
How does it work?
You compose a URI to describe the data you want:
