Welcome to the Momentum Fastighet API Docs
Momentum Fastighet offers a suite of open APIs designed to support
seamless integration across your digital ecosystem.
Our APIs empower property owners, managers, and developers to
streamline operations, improve tenant services, and connect with
modern applications.
Why use our APIs?
With Momentum's APIs, you can unlock real estate data in a secure
and structured way. Whether you're building internal tools or
integrating external platforms, our APIs enable access to essential
information such as lease agreements, tenants, and errand
management.
This means faster service, less manual work, and a better
experience for both staff and tenants.

Built for Property Management
These APIs are developed specifically for real estate operations.
They support common workflows such as lease lifecycle handling,
customer self-service, and digital errand management. With clear
business logic and smart filtering per authenticated tenant,
integrations are both secure and context-aware.
APIs are updated continuously to reflect changes in your source
systems, using an "eventual consistency" model. This ensures
accurate data without requiring direct, real-time system
connections.
