Open to everyone
Any software can work with Heimster.
A good product needs no walls. Data comes in through open standards and goes out the same way – for agents, networks and every software that wants to work with us.
Standards
In and out – through open channels.
REST API with OAuth
Read and write contacts, objects, listings, prospects, viewings, leads and shared properties – with API keys or OAuth, documented as OpenAPI.
Webhooks
New applications, leads, booked viewings, deals and network registrations reach your system in real time.
IDX 3.01
The portal standard: Heimster delivers to the portals and receives deliveries from your existing agency software – by upload or API, FTP on request.
SwissRETS
The open Swiss exchange format: as an export per object, as a feed and as a delivery to Heimster (upload, API or feed URL).
CSV, vCard and full export
Import and export contacts, prospects as CSV, and all your agency's data as one package at any time – no questions asked.
MCP for AI assistants
ChatGPT, Claude and Copilot work with your Heimster data – with your permissions, actions only after your confirmation.
Networks
Collaboration across software.
Agencies share properties and register clients with each other – even when not everyone works with Heimster.
Agencies without Heimster take part as guests: they keep their software, deliver by IDX or SwissRETS and decide on registrations by e-mail link.
Everything partners share with you is available as a SwissRETS feed for your own CRM.
Shared properties, registrations and decisions through the API and webhooks – so any software can connect without asking us.
