Mollie Payment Processor API

This package contains wrapper- & helper methods for the Mollie API to process payments and refunds.

Configuration

Optional helper class to bind your API keys to the configuration. This one is not directly used in this package but can be passed in a request's AccessToken property.

In case of pasting your Mollie account's API key:

  • Add your test API-key to your appsettings.Development.json.
  • Add your live API-key to your appsettings.json.

If you have an organizational access token, paste that one in since that has more access than your API key.

{
  "MollieAuthConfig": {
    "AccessToken": "<to-fill>",
    "IsApiKey": true
  }
}

Program.cs

builder.Services
    .AddOptions<MollieAuthConfig>()
    .BindConfiguration(nameof(MollieAuthConfig));

Payment API

Configuration

{
  "MollieConfig": {
    "ApiUrl": "https://api.mollie.com/v2/",
    "IsTestMode": false,
    "PaymentsConfig": {
      "WebhookUrl": "<to-fill>"
    }
  }
}

The WebhookUrl should be set to the API endpoint you expose to handle the Mollie webhook's payment status notifications.
