Why does the Google Analytics API method return less data than web ui

Question

Do the Google Analytics API methods allow to get the same amount of data, that is accessible through the web UI?

The problem is, for example, that in browser I can see more that 3000 lines in a report, but the API method returs only several hundreds.

Here is a URL for API method that I use: https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A73XXXXXX&dimensions=ga%3ApagePath%2Cga%3Akeyword&metrics=ga%3Avisits%2Cga%3AvisitBounceRate&sort=-ga%3Avisits&start-date=2015-09-01&end-date=2015-09-30&start-index=1&max-results=3000

Answer 1

The API method you are using has queries appended on it. (Everything after the '?' and seperated by the '&') These are not part of the URL but actually information that is used by the server to customize your result. By changing the URL to say: https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A73XXXXXX&dimensions=ga%3ApagePath%2Cga%3Akeyword&metrics=ga%3Avisits%2Cga%3AvisitBounceRate&sort=-ga%3Avisits&start-date=2015-09-01&end-date=2015-09-30&start-index=1&max-results=10000 , you should get more results in your response. You may also want to change the start and end date, just make sure to keep the YYYY-MM-DD format.
