This library was built by the community and is not maintained by the PostHog core team.

This library provides an Elixir HTTP client for PostHog. See the repository for more information.

Installation

The package can be installed by adding posthog to your list of dependencies in mix.exs:

def deps do

Posthog.capture("login", distinct_id: user.id)

Capturing multiple events:

Posthog.batch([{"login", [distinct_id: user.id], nil}])

Thanks
