Disclaimer

This is the unofficial Crystal shard for Mollie. It is directly ported from the Ruby version (mollie-ruby-api) but not an exact copy. Usage might vary from the Ruby version due to language differences and to make the most of Crystal's type system.

• Get yourself a free Mollie account. No sign up costs.
• Create a new Website profile to generate API keys (live and test mode) and setup your webhook.
