R package for accessing data from Piwik PRO via API.
This R-Package uses the API to fetch the data from PIWIK PRO using R-code. You get the data as tibble (or as a data.frame). So it’s easy to analyze the data with the whole power of R.
The package is now available on CRAN. So you can install it by running
devtools it’s easy to install piwikproR:
First you need to setup an access to the API. See here: [https://developers.piwik.pro/en/latest/platform/getting_started.html#create-api-credentials-and-an-access-token]
Let’s say you put them into a list:
piwik_pro_credentials <- list( client_id = "my_client_id", client_secret = "my_client_secret", url = "https://my_site.piwik.pro" )
Using these credential you can fetch a token
token <- get_login_token(piwik_pro_credentials)
## Website id Set the website_id and the date range.
website_id <- 'my_website_id' start.date <- "2021-04-01" end.date <- "2021-04-30"
Now we define the columns we want to fetch. Here’s an example:
We want to fetch the date, the url (only the path without the hostname) and the page_views:
columns <- tibble::tribble( ~column, ~transformation, "timestamp", "", "event_url", "to_path", "page_views", "", )
## Filters We’re only interested in – let’s say – Desktop requests. So let’s set a filter:
filters <- tibble::tribble( ~column, ~operator, ~value, "device_type", "eq", 0 ) filters <- build_filter(filters, "and")
## Fetching the data
query <- build_query(lubridate::ymd(start.date), lubridate::ymd(end.date), website_id, filters = filters, columns, max_lines = 0 ) data <- send_query(query, token, caching = TRUE, fetch_by_day = FALSE)
PIWIK PRO offers a great documentation of all metrics and dimensions starting here [https://developers.piwik.pro/en/latest/custom_reports/index.html]
I’m using unit tests to test my code. But these tests run against a special website_id whose data is not publicly available. So I put all those sensitive data into a private package
piwikproRTests. If this package is not available all tests are skipped.
If you find a bug or if you have a feature request feel free and open an issue
