  # just by starting a chat with https://t.me/mailanes_bot

# If this is set to TRUE an email right after being added
# to this list will be de-activated in all other lists
exclusive: true
# If this is TRUE, all new recipients that get into the list via the
# /subscribe link, will be marked as non-yet-confirmed. They will have
# to click the link, which is available in your Markdown template
# as {{confirm}} (similar to the {{unsubsribe}} you have there).
# The default is FALSE.

API

You can retrieve the data from the system via the API. First, you have to get the authorization code from the API page. Then, add it to each HTTP request you make, as auth URI parameter. For example, to see the total count of all active subscribers of your list:

/api/lists/123/active_count.json?auth=74fa8672...

All URIs:

• /api/lists/:id/active_count.json: total active subscibers in the list
• /api/lists/:id/per_day.json: new subscribers per day (last 10 days stat, change with days)
• /api/campaigns/:id/deliveries_count.json: deliveries per day (last day, change with days)
• more coming...

How to contribute

Read these guidelines. Make sure you build is green before you contribute your pull request. You will need to have Ruby 2.3+, Java 8+, Maven 3.2+, PostgreSQL 10+, and Bundler installed. Then:

$ bundle update
$ bundle exec rake

If it's clean and you don't see any error messages, submit your pull request.

To run a single unit test you should first do this:

$ bundle exec rake pgsql liquibase run

And then, in another terminal (for example):

$ bundle exec ruby test/test_campaign.rb -n test_iterates_lists

Should work.
