# Pirsch API Ruby Gem
This is a simple wrapper to read the Pirsch Analytics API with Ruby.
It's based on the [API guide](https://docs.pirsch.io/api-sdks/api/)

## Usage
Add this gem to your Gemfile:
```rb
gem 'pirsch_api'
```
Then you need to initialize a Client with your `client_id` and the `client_secret`.
```rb
c = PirschApi::Client.new(client_id: '<client_id>', client_secret: '<client_secret>') 

# Test if the credentials are valid
c.valid?
=> true

# Get /domains
c.domains
=> [#<PirschApi::Domain id="0D3a...", user_id="0D3a...", hostname="pirsch.io", subdomain="pirsch", ... >]
c.domains.first.hostname
=> "pirsch.io"

# You will need one domain for all the following requests
d = c.domains.first

# All the following methods require a `domain` and can receive a `filters` hash

# Get /statistics/visitor
c.visitors(domain: d)
=> [#<PirschApi::Visitor day="2021-08-30T00:00:00Z", visitors=87, views=200, sessions=125, bounces=53, bounce_rate=0.6091954022988506>, #<PirschApi::Visitor day="2021-08-31T00:00:00Z", visitors=77, views=159, sessions=113, bounces=49, bounce_rate=0.6363636363636364>, #<PirschApi::Visitor day="2021-09-01T00:00:00Z", visitors=76, views=161, sessions=110, bounces=48, bounce_rate=0.631578947368421>, #<PirschApi::Visitor day="2021-09-02T00:00:00Z", visitors=79, views=152, sessions=130, bounces=52, bounce_rate=0.6582278481012658>, #<PirschApi::Visitor day="2021-09-03T00:00:00Z", visitors=53, views=109, sessions=68, bounces=26, bounce_rate=0.49056603773584906>, #<PirschApi::Visitor day="2021-09-04T00:00:00Z", visitors=54, views=126, sessions=71, bounces=31, bounce_rate=0.5740740740740741>, #<PirschApi::Visitor day="2021-09-05T00:00:00Z", visitors=116, views=202, sessions=131, bounces=84, bounce_rate=0.7241379310344828>, #<PirschApi::Visitor day="2021-09-06T00:00:00Z", visitors=1, views=1, sessions=1, bounces=1, bounce_rate=1>]
