STACKIT Domain Services API

Last updated on

Welcome to our API developer portal! Our RESTful API provides a powerful interface for the programmatic management of your entire domain and DNS infrastructure. From automated domain registration to highly available DNS management with enterprise-locking features – our API is designed to accelerate and secure your workflows.

Start with the OTE System (Testing Environment)

Section titled “Start with the OTE System (Testing Environment)”

We place great value on stability. Therefore, we offer a dedicated testing system (OTE). The OTE system is an identical copy of our production environment, but does not run real, fee-based domain orders.

  • Risk-free testing: Develop and test your scripts without affecting real DNS zones.
  • Process validation: Simulate the entire order workflow from availability checks to contact management.
  • Cost control: No registration fees are incurred in the OTE.

Access to the OTE system is not active by default. To receive your test credentials, please send us a short email:

  • Contact: domainservices@stackit.cloud
  • Subject: Request API access for OTE system
  • Required Info: Email addresses of the people to be invited

Here you will find the base URLs for your integration. Please ensure that you exclusively use the OTE endpoints during development.

  1. Request your OTE access via our support.
  2. Follow our authentication guide to generate your first JWT token.
  3. Use the Organization API to retrieve your available IDs.

On the following pages, you will find a complete technical reference for each area of our API. We have structured the documentation so that you can get from the first idea to the finished integration as quickly as possible.

In addition to this documentation, we provide the complete API definition in YAML format (OpenAPI 3.0.1). This is the most efficient method for developers to quickly start with the integration.
