Introducing API v4: Streamlined data management is here

We've upgraded our API to help you future-proof your real estate portfolio. We're excited to announce the launch of Hello Energy API v4. This new version makes it easier to access data directly from Hello Energy and integrate it into your applications or create customised reports

‍
What's new?

• User-friendly design
  The Hello Energy API is built for simplicity. It follows REST principles and uses the HTTP protocol, making communication straightforward and easy to troubleshoot. Expect predictable, resource-oriented URLs and clear HTTP response codes for any errors.
• Comprehensive documentation
  Our documentation page allows you to explore the API easily. You can try out requests, view examples in various programming languages, and learn how to use the API effectively.
• Robust authentication with OAuth2
  Security is a priority, which is why we’ve implemented OAuth2 client credential flow for authentication. To get started, contact support@hello-energy.com for your access credentials.
• Easy transition from API v3
  Hello Energy API v4 will eventually replace the older version (API v3). While API v3 will still be available for now, we recommend migrating to v4 for better security and ongoing support. This version will receive regular updates and new features, without breaking the existing interface.
