Koppla API is published by [Koppla](https://apis.io/providers/koppla/) on the [APIs.io](https://apis.io/) network. Tagged areas include Scheduling, Construction, and Project. The published artifact set on APIs.io includes API documentation.

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.
