CustomerOS GraphQL API is one of 4 APIs that [CustomerOS](https://apis.io/providers/customeros/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include GraphQL. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Single GraphQL endpoint served by the open-source customer-os-api (Go, gqlgen) covering organizations, contacts, opportunities, contracts, invoices, interactions and timeline events. The repository moved with the rename: github.com/openline-ai/openline-customer-os now 301s to github.com/customeros/customeros, where 69 .graphqls schema files are published. Introspection could not be run — the published endpoint host does not resolve.
