You can use open source tools, such as the [OpenAPI Generator](https://openapi-generator.tech), with the provided [API Reference](https://developer.mastercard.com/commercial-event-notifications/documentation/parameters/index.md), to generate an API client. When used with the provided [client authentication libraries](https://developer.mastercard.com/platform/documentation/security-and-authentication/using-oauth-1a-to-access-mastercard-apis/), and if applicable, [client encryption libraries](https://developer.mastercard.com/platform/documentation/security-and-authentication/securing-sensitive-data-using-payload-encryption/#client-libraries), this is an agile and powerful way to get started with real code to access the service.
