Koppla

koppla GmbH is a Potsdam, Germany based construction technology company building Bauterminplan (construction scheduling) software for general contractors, general planners, project developers and architects. The cloud platform combines lean-construction scheduling, day-to-day project control and collaboration, standardized company-wide templates, reporting and analytics, a jobsite mobile app, AI-assisted import of existing schedules from MS Project, Asta Powerproject and Primavera, and a BIM integration that adds the time dimension (4D) to the model. koppla states that more than 100 construction companies and 600+ live projects run on the platform, covering over EUR 15 billion of managed construction volume. An open interface (API) plus a Power BI integration are offered as part of the Enterprise plan; koppla does not publish a public developer portal, API reference or machine-readable specification, so the API is available under contract rather than via self-service onboarding.

Koppla publishes 1 API on the APIs.io network. Tagged areas include Company, Construction, Construction Technology, Project Management, and Scheduling.

Koppla’s developer surface includes signup flow, support, engineering blog, pricing, YouTube channel, authentication, and 29 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/koppla: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →

  description: koppla advertises an "Offene Schnittstelle / API" (open interface / API) as an included capability of its Enterprise
    plan, alongside a Power BI integration that pushes koppla schedule data into customer reporting, and a BIM integration
    that carries schedule data into the 3D model. The live surface is a GraphQL API at https://api.koppla.de/api/graphql/v1
    - 384 types, 73 queries and 81 mutations covering projects, orders (scheduled activities), tickets, milestones, trade
    sequences, memberships, photos and exports. It uses Relay cursor connections throughout, bearer-token auth backed by WorkOS
    SSO, and role-based multi-tenant access. Schema introspection is answered without credentials (which is how this profile
    captured the schema) while data access is correctly gated behind UNAUTHENTICATED. There is no idempotency mechanism. 45
    fields are deprecated with stated replacements, six of them pointing at an in-progress REST API (api-v2.koppla.de). koppla
    publishes no developer portal, API reference, SDK or sandbox; access is provisioned per Enterprise contract.
