The v5 API is deprecated

The v5 API is deprecated and will be sunset on June 30, 2027. Please follow the migration guide to move to the latest stable Omnisend API version.

Introducing API v5:

We're excited to announce a simplified version of the Omnisend API (v5) - designed for easier integration, clearer capabilities, and improved functionality.

Benefits of v5:

  • Simplified API: v5 streamlines the API structure compared to v3, making it easier to understand and integrate into your workflows.
  • Enhanced Capabilities: v5 offers new features and functionalities to better support your needs.
    Focus on Events: The future lies in events, and v5 is built around this concept, providing a centralized hub for event-driven actions.
  • Guides: with v5, we introduce guides that help you achieve your desired use case by demonstrating actual steps required.

Next Steps:

For detailed information on using v5, please refer to our comprehensive guides or the events documentation. Don't hesitate to reach out to our support team if you have any questions.
